LAYER SOLAR CONTROL COATINGS OF DISCONTINUOUS METAL Reference to Related Order [001] The present application claims the priority of United States Provisional Patent Application No. 61 / 318,471, filed on March 29, 2010, which is incorporated in this context by reference in its entirety. Field of the Invention [002] The present invention is generally referred to as solar control coatings and, in a particular embodiment, to a solar control coating that is provided with increased asymmetric absorbance and reflectance. Technical Considerations [003] Solar control coatings are known in the fields of architectural and automotive transparencies. These solar control coatings block or filter selected bands of radiation and l and t romagnetic t i c a, such as in the range of solar infrared and solar ultraviolet radiation, to reduce the amount of solar energy entering the vehicle or building. This reduction in the transmission of solar energy helps to reduce the load on the cooling units of the vehicle or building. In automotive applications, transparency (such as a windshield) is typically required to have a relatively high visible light transmission, such as greater than 70 percent, in order to allow passengers to see outside the vehicle. vehicle. For architectural applications, visible light transmission may be lower. In some architectural applications, it can be designed Petition 870190035436, of 12/12/2019, p. 6/81 2/68 it is feasible to have a reflective outer surface in order to decrease visibility into the building in order to retain the greatest possible privacy, while allowing visible light to enter the building and also allowing people working inside of the building look out. In addition, these transparencies are typically tempered or heat treated for increased security. [004] In a known architectural transparency, a hot-reinforced glass substrate is coated with a solar control coating that is provided with an absorbent material, such as a nickel-chromium alloy material (eg Inconer), to absorb visible light to darken the window. This transparency also includes a continuous, relatively thick, infrared reflecting metal layer to reflect sunlight, such as solar infrared energy. However, a problem with this known transparency lies in the fact that the glass substrate must be cut to a desired shape and tempered before the coating is applied. If the coating is applied before the glass substrate is tempered, the resulting coating becomes cloudy during the high temperature processing required for the tempering process. This dry mist is aesthetically undesirable. [005] It would be desirable to be able to apply a solar control coating on non-tempered glass sheets and transport the glass sheets to a manufacturer who could then cut the sheets to a desired size for a particular job and then have Petition 870190035436, of 12/12/2019, p. 7/81 3/68 pear or heat treated the cut pieces without adversely affecting the aesthetic or solar control properties of the resulting transparency.

Description of Preferred Embodiments [0017] As used in this context, spatial terms such as left, right, internal, external, above, below, and the like, Petition 870190035436, of 12/12/2019, p. 13/81 9/68 refer to the invention as it is shown in the figures of the drawings. However, it must be understood that the invention can support several alternative orientations and, therefore, these terms should not be considered as limiting. In addition, all numbers expressing dimensions, physical characteristics, processing parameters, quantities of ingredients, reaction conditions, and so on, used in the report and claims must be understood to be modified in all cases by the term “approximately . Consequently, unless otherwise indicated, the numerical values set out in the following report and claims may vary depending on the desired properties considered to be capable of being obtained by the present invention. At least, and not in an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be considered in the light of the number of significant digits reported and by the application of rounding techniques. In addition, all bands exposed in this context should be considered as covering any and all subordinate sub-bands within them. For example, an established range of “1 to 10” should be considered to include any and all sub-ranges between (and including) the minimum value of 1 or more and ending with a maximum value of 10 or less, for example, 1 to 3.3, 4.7 to 7.5, 5.5 to 10 and the like. Likewise, as used in this context, the terms "formed on", "deposited on", or "providing on" mean formed, deposited, or provided on, but not Petition 870190035436, of 12/12/2019, p. 14/81 10/68 necessarily in contact with the surface. For example, a coating layer “formed on a substrate does not prevent the presence of one or more other coating layers or films of the same or different composition located between the formed coating layer and the substrate. As used in this context, the terms "polymer or" polymeric include oligomers, homopolymers, copolymers, and terpolymers, for example, polymers formed from two or more types of monomers or polymers. The terms "visible region or" visible light refer to electromagnetic radiation that has a wavelength in the range of 380 nm to 800 nm. The terms "infrared region or" infrared radiation refer to electromagnetic radiation that has a wavelength in the range that is greater than 800 nm to 100,000 nm. The terms "ultraviolet region or" ultraviolet radiation mean electromagnetic energy that has a wavelength in the range of 300 nm to less than 380 nm. In addition, all documents, such as, but not limited to, issued patents and patent applications, referred to in this context should be considered as “being incorporated by reference in their entirety. As used in this context, the term "film refers to a coating region of a desired or selected coating composition. A "layer may comprise one or more" films, and a "coating or" coating stack may comprise one or more "layers. The term “asymmetric reflectivity means that the visible light reflectance of the coating Petition 870190035436, of 12/12/2019, p. 15/81 11/68 from one side is different from that of the coating from the opposite side. The term "critical thickness means a thickness above which a coating material forms a continuous, uninterrupted layer, and below which the coating material forms discontinuous or islet regions of the coating material instead of a continuous layer. The term "subcritical thickness means a thickness below the critical thickness in such a way that the coating material forms isolated, unconnected regions of the coating material. The term islet means that the coating material is not made up of a continuous layer, but rather that the material is deposited to form isolated or islet regions. [0018] For the purposes of the following exhibition, the invention will be discussed with reference to its use with architectural transparency, such as, but not limited to, an insulating glass unit (IGU). As used in this context, the term architectural transparency refers to any transparency located in a building, such as, but not limited to, windows and skylights. However, it must be understood that the invention is not limited to use with such architectural transparencies, but can be put into practice with transparencies in any desired field, such as, being not limited to, residential and / or commercial windows. laminated or non-laminated, insulating glass units, and / or transparencies for land, air, space vehicles, above water and below water (submarines). For that reason, Petition 870190035436, of 12/12/2019, p. 16/81 12/68 be understood that the exemplary embodiments specifically exposed are presented simply to expose the general concepts of the invention, and that the invention is not limited to these specific exemplary embodiments. In addition, although a typical transparency may be endowed with light transmission sufficiently visible so that materials can be visualized through transparency, in the practice of the invention, transparency does not need to be transparent to visible light, but it can be translucent or opaque. [0019] A non-limiting transparency 10 that incorporates aspects of the invention is illustrated in Figure 1. Transparency 10 can be provided with any transmission and / or reflection of desired visible light, infrared radiation, or ultraviolet radiation. For example, transparency 10 can be provided with a light transmission of any desired quantity, for example, greater than 0% to 100%. [0020] The exemplary transparency 10 of Figure 1 is in the form of a conventional insulating glass unit and includes a first layer 12 with a first main surface 14 (surface No. 1) and a second opposite main surface 16 ( surface No. 2). In the illustrated non-limiting embodiment, the first main surface 14 faces towards the outside of the building, that is, it is comprised of an external main surface, and the second main surface 16 faces towards the interior of the building. Transparency 10 also includes a second layer 18 which is provided with a (first) main surface ex Petition 870190035436, of 12/12/2019, p. 17/81 13/68 tender 20 (surface No. 3) and an internal (second) main surface 22 (surface No. 4) and spaced in relation to the first layer 12. This numbering of the surfaces of the layers is in accordance with conventional practice in fenestration technique. The first and second layers 12, 18 can be connected together in any suitable manner, such as by means of adhesive bonding to a conventional spacing frame 24. A gap or chamber 26 is formed between the two layers 12, 18. The chamber 26 can be filled with a selected atmosphere, such as air, or a non-reactive gas, such as argon or krypton gas. A solar control coating 30 (or any of the other coatings described below) is formed on at least a part of one of the layers 12, 18, such as, but not limited to, on them least part of the surface 16 N °. 2 or at least a part of the surface 20 N °. 3. Although, if desired, the coating can also be the No. surface. 1 or the surface No. 4. Examples of insulating glass units are found, for example, in U.S. Patent Nos. 4,193,236; 4,464,874; 5,088,258; and 5,106,663. [0021] In the broad practice of the invention, layers 12, 18 of transparency 10 can be of the same or different materials. The layers 12, 18 can include any desired material that is provided with any of the desired characteristics. For example, one or more of the layers 12, 18 can be transparent or translucent to the visible Liz. Transparent means that it has a visible light transmission of more than 0% to 100%. AlPetição 870190035436, from 12/12/2019, p. 18/81 14/68 ternatively, one or more of the layers 12, 18 can be translucent. Translucent is meant to allow electromagnetic energy (for example, visible light) to pass through, but by spreading this energy in such a way that objects on the opposite side of the observer are not clearly visible. Examples of materials that are suitable include, but are not limited to, plastic substrates (such as acrylic polymers, such as polyacrylates; polyalkyl methacrylates, such as polymethyl methacrylates, polyethyl methacrylates, polypropyl methacrylates, and the like ; polyurethanes; polycarbonates; polyalkyl terephthalates, such as polyethylene terephthalate (PET), polypropylene terephthalates, polybutylene terephthalates, and the like; polymers containing polysiloxane; or copolymers of any monomers or compounds for the preparation of stems r mixtures thereof); ceramic substrates; glass substrates; or mixtures or combinations of any of the above. For example, one or more of the layers 12, 18 can include conventional soda-lime-silicate glass, borosilicate glass, or leaded glass. The glass can be clear glass. Transparent glass means unpainted or uncolored glass. Alternatively, the glass can be painted or otherwise colored. The glass can be annealed or heat treated glass. As used in this context, the term "heat treated" means tempered or at least partially tempered. The glass can be of any type, such as conventional float glass, and can be of any composition Petition 870190035436, of 12/12/2019, p. 19/81 15/68 that has any optical properties, for example, any visible transmission value, ultraviolet transmission, infrared transmission, and / or total solar energy transmission. By "float glass" is meant glass that is formed by means of a conventional float process in which molten glass is deposited in a molten metal bath and cooled in a controlled manner to form a float glass ribbon. Examples of float glass processes are set out in U.S. Patent Nos. 4,466,562 and 4,671,155. [0022] The first and second layers 12, 18 can each be, for example, transparent float glass or can be painted or colored glass or a layer 12, 18 can be transparent glass and the other layer 12, 18 glass colorful. While not limiting to the invention, examples of glass suitable for the first layer 12 and / or second layer 18 are described in U.S. Patent Nos. 4,746,347; 4,792,536; 5,030,593; 5,030,594; 5,240,886: 5,385,872; and 5,393,593. The first and second layers 12, 18 can be of any desired dimensions, for example, length, width, shape, or thickness. In an exemplary automotive transparency, the first and second layers can each be from 1 mm to 10 mm thick, such as from 1 mm to 8 mm thick, such as from 2 mm to 8 mm, such as from 3 mm to 7 mm, such as from 5 mm to 7 mm, such as 6 mm thick. Non-limiting examples of glass that can be used for the practice of the invention include clear glass, Starphire glass, Solar glass Petition 870190035436, of 12/12/2019, p. 20/81 16/68 green®, Solextra® glass, GL-20® glass, GL-35 T 'glass, Solarbronze® glass, Solargray® glass, Pacifica® glass, SolarBlue® glass, and Optiblue0 glass, all commercially available from PPG Industries Inc. of Pittsburgh, Pennsylvania. [0023] The solar control coating 30 of the invention is deposited on at least part of at least one main surface of one of the layers of glass 12, 18. In the example shown in Figure 1, the coating 30 is formed on at least part of the inner surface 16 of the outer glass layer 12. As used in this context, the term "solar control coating" refers to a coating comprised of one or more layers or films that affect solar properties of the coated article, such as, but not limited to, the amount of solar radiation, for example, visible, infrared, ultraviolet radiation, reflected from absorbed by, or passing through the coated article; shading coefficient; emissivity and the like. The solar control coating 30 can block, absorb, or filter selected parts of the solar spectrum, such as, but not limited to, the IR, UV, and / or visible spectra. [0024] The solar control coating 30 can be deposited using any conventional method, such as, but not limited to, conventional chemical vapor deposition (CVD) and / or physical vapor deposition methods (PVD). Examples of CVD processes include spray pyrolysis. Petition 870190035436, of 12/12/2019, p. 21/81 17/68 Examples of PVD processes include electron beam evaporation and vacuum cathodic sublimation (such as vapor deposition by magnetron cathodic sublimation (MSVD)). Other coating methods may also be used, such as, but not limited to, deposition by sol-ge. According to a non-limiting embodiment, the coating 30 can be deposited by means of MSVD. Examples of MSVD coating devices and methods will be readily understood by one of ordinary skill in the art and are described, for example, in U.S. Patent Nos. 4,379,040; 4,861,669; 4,898,789; 4,898,790; 4,900,633; 4,920,006; 4,938,857; 5,328,768; and 5,492,750. Illustrated Metal Layer [0025] An exemplary, non-limiting solar control coating 30 of the invention is illustrated in Figure 2. This exemplary coating 30 includes a base layer or first dielectric layer 40 deposited on at least part of the main surface of a substrate (for example, surface 16 No. 2 of first layer 12). The first dielectric layer 40 may be a single layer or may comprise more than one film of anti-reflective materials and / or dielectric materials, such as, but not limited to, metal oxides, metal alloy oxides, nitrides , oxynitrides, or mixtures thereof. The first dielectric layer 40 can be transparent to visible light. Examples of metal oxides that are suitable for the first dielectric layer 40 include oxides of titanium, hafnium, zirconium, niobium, zinc, bismuth, Chum Petition 870190035436, of 12/12/2019, p. 22/81 18/68 bo, indium, tin, as well as their mixtures. These metal oxides can be endowed with small amounts of other materials, such as manganese in bismuth oxide, tin in indium oxide, and the like. In addition, oxides of metal alloys or mixtures of metals may be used, such as oxides containing zinc and tin (for example, zinc stannate, which is defined below), oxides of tin and indium alloys, silicon nitrides , silicon and aluminum nitrides, or aluminum nitrides. In addition, induced metal oxides, such as antimony or indium-induced tin oxides or antimony or indium-induced silicon oxides, can be used. The first dielectric layer 40 may be a substantially single phase film, such as a metal alloy oxide film, for example, zinc stanate, or it may be a mixture of phases composed of zinc oxides or this may be be composed of a plurality of films. [0026] For example, the first dielectric layer 40 (be it a single film layer or several films) can be provided with a thickness in the range of 100  to 600 Â, such as 200  to 500 Â, such as 250  to 350 Â, such as 250  to 310 Â, such as 280  to 310 Â, such as 300  to 330 Â, such as 310  to 330 Â. [0027] The first dielectric layer 40 may comprise a structure of several films, which is provided with a first film 42, for example, a metal alloy oxide film, deposited on at least a part of a substrate (such as surface Petition 870190035436, of 12/12/2019, p. 23/81 19/68 inner main 16 of the first layer 12) and a second film 44, for example, a metal oxide film or mixture of oxides, deposited on the first metal alloy oxide film 42. According to a non-limiting embodiment , the first film 42 may be zinc and tin alloy oxide. By zinc and tin alloy oxide ”is meant both true alloys and also mixtures of oxides. The oxide of the zinc and tin alloy can be that obtained from vacuum deposition by cathodic sublimation of magnetrons from a zinc and tin cathode. A non-limiting cathode can comprise zinc and tin in proportions of 5%, by weight, up to 95%, by weight, of zinc and 95%, by weight, up to 5%, by weight, of tin, such as 10%, in weight up to 90% by weight of zinc and 90% by weight up to 10% by weight of tin. However, other proportions of zinc to tin can also be used. A suitable metal alloy oxide that may be present in the first film 42 is comprised of zinc stannate. By zinc stannate ”is meant a composition of ZnxSni-x02-x (Formula 1) in which x” ranges from more than 0 to less than 1. For example, x ”can be greater than 0 and can be any fraction or decimal located greater than 0 to less than 1. For example, where x = 2/3, Formula 1 is comprised of Zn2 / aSn1 / 304/3, which is most commonly described as being Zn2SnO4 ” . A film containing zinc stanate is provided with one or more of the forms of Formula 1 in an amount predominant in the film. [0028] The second film 44 can be a film Petition 870190035436, of 12/12/2019, p. 24/81 20/68 metal oxide cell, such as zinc oxide. The zinc oxide film can be deposited from a zinc cathode that includes other materials to improve the cathodic sublimation characteristics of the cathode. For example, the zinc cathode may include a small amount (for example, up to 10% by weight, such as up to 5% by weight) of tin to enhance cathodic sublimation. In this case, the resulting zinc oxide film will include a small percentage of tin oxide, for example, up to 10%, by weight of tin oxide, for example, up to 5%, by weight of tin oxide. A coating layer deposited from a zinc cathode that is provided with up to 10% by weight of tin (added to increase the conductivity of the cathode) is referred to in this context as “a zinc oxide film” even though it may a small amount of tin is present. A small amount of tin in the cathode (for example, less than or equal to 10% by weight, such as less than or equal to 5% by weight) is believed to form tin oxide in the second film 44 predominantly of zinc oxide. [0029] Per example, The first film 42 can to be constituted in stannate in zinc and the second pelícu- there 44 can be constituted in oxide zinc (for example plo , 90% by weight, of oxide in zinc and 10%, in weight of tin oxide). For example, the first film 42 may comprise zinc stanate which is provided with a thickness in the range of 50  to 600 Â, such as 50  to 500 Â, such as 75 A to 350 Â, such as 100  to 250  Â, such as 150  to 250 Â, such as 195 A to 250 Â, Petition 870190035436, of 12/12/2019, p. 25/81 21/68 such as 200  to 250 Â, such as 200  to 220 Â. [0030] The second film 44 may comprise zinc oxide which has a thickness in the range of 50  to 200 Â, such as 75 A to 200 Â, such as 100  to 150 Â, such as 100  to 110 THE. [0031] A first heat and / or radiation reflective metallic layer 46 can be deposited on the first dielectric layer 40. The first reflective layer 46 can include a reflective metal, such as, but not limited to, gold, copper, palladium, aluminum, metallic silver, or mixtures, alloys, or combinations thereof. According to one embodiment, the first reflective layer 46 comprises a layer of metallic silver which has a thickness in the range of 50  to 300 Â, for example, 50  to 250 Â, for example, 50  to 200  , such as 70  to 200 Â, such as 100  to 200 Â, such as 125 A to 200A, such as 150  to 185 Â. The first metallic layer 46 is comprised of a continuous layer. By "continuous layer" it is understood that the coating forms a continuous film of the material and not isolated regions of coating. [0032] A first layer of preparator 48 is located on the first reflective layer 46. The first layer of preparator 48 can be a single film layer or a layer of several films. The first layer of preparator 48 can include an oxygen capture material that can be sacrificial during the deposition process to prevent degradation or oxidation of the first reflective layer 46 during the cathodic sublimation process or subsequent heating processes. The first Petition 870190035436, of 12/12/2019, p. 26/81 22/68 layer of preparator 48 can also absorb at least a part of electromagnetic radiation, such as visible light, which passes through the coating 30. Examples of useful materials for the first layer of preparator 48 include titanium, silicon, silicon dioxide , silicon nitride, silicon oxinitride, nickel and chromium alloys (such as Inconel), zirconium, aluminum, silicon and aluminum alloys, alloys containing cobalt and chromium (eg Ste llite®), as well as their mi sturas. For example, the first layer of preparator 48 can be titanium and can have a thickness in the range of 5 A to 50 Â, for example, 10  to 40 Â, for example,  up to 40 Â, for example, 20  up to 35 A. [0033] A second dielectric layer 50 is located on the first reflective layer 46 (for example, on the first layer of preparator 48). The second dielectric layer 50 may comprise one or more films containing metal oxide or metal alloy oxide, such as those described above with respect to the first dielectric layer 40. For example, the second dielectric layer 50 may include a first oxide film of metal 52, for example, a film of zinc oxide, deposited on the first film of preparer 48 and a second film of metal oxide 54, for example, a film of zinc stanate (Zn2SnO4), deposited on the first zinc oxide film 52. A third metal oxide film 56, for example, another zinc oxide layer, can be deposited on the zinc stannate layer. [0034] The second dielectric layer 50 can be Petition 870190035436, of 12/12/2019, p. 27/81 23/68 with a total thickness (for example, the combined thicknesses of the layers) is in the range of 50  to 1000 Â, for example, 50  to 500 Â, for example, 100  to 370 Â, for example, 100  to 300 Â, for example, 100  to 200 Â, for example, 150  to 200 Â, for example, 180  to 190 Â. [0035] For example, for a layer of several films, the zinc oxide film 52 (and optional second zinc oxide film 56, if present) may have a thickness ranging from 10  to 200 Â, for example, 50  to 200 Â, for example, 60  to 150 Â, for example, 70  to 85 Â. The metal oxide layer (zinc stanate) 54 can be healthy. of a thickness located in range 50 THE up until 800 THE for example, 50  to 500 Â, per example, 100 THE up until 300 THE for example, 110  to 235 Â, for example 110 THE up until 120 THE [0036] A second metallic layer 58 in thick- subcritical (discontinuous) sura, it is located on the second dielectric layer 50 (for example, on the second zinc oxide film 56, if present, or on the zinc stanate film 54 if not). The metallic material, such as, but not limited to, gold, copper, palladium, aluminum, metallic silver, or mixtures, alloys, or combinations thereof, is applied under a subcritical thickness in such a way that isolated regions or islets of the material are formed in place of a continuous layer of the material. For silver it was determined that the critical thickness is less than 50 Å, such as less than 40 Å, such as less than 30 Å, such as less than 25 Å. For silver, the transition between Petition 870190035436, of 12/12/2019, p. 28/81 24/68 a continuous layer and a subcritical layer occur in the range of 25  to 50 Â. Copper, gold and palladium are expected to exhibit similar subcritical behavior in this range. The second metallic layer 58 may include any one or more of the materials described above with respect to the first reflective layer 46, but these materials are not present in the form of a continuous film. According to a non-limiting embodiment, the second layer 58 comprises silver island with the islets having an effective thickness located in the range 1 THE up until 70 THE per example 10 THE up until 40 THE per example, 10 THE up until 35 THE per example 10 THE up until 30 THE per example, 15 THE up until 30 THE per example, 20 THE up until 30 THE per example, 25 THE up until 30 THE THE metallic layer subcritical 58 absorbs electromagnetic radiation according to Plasmon Resonance Theory. This absorption depends at least partially on the boundary conditions at the interface of the metal islets. Subcritical metallic layer 58 is not an infrared reflective layer, like the first metallic layer 46. Subcritical silver layer 58 is not a continuous layer. It is estimated that for silver, islets or metal balls of silver metal deposited below the subcritical thickness may have a height of about 2 nm to 7 nm, such as 5 nm to 7 nm. It is estimated that if the subcritical silver layer can be spread evenly, it will have a thickness of about 1.1 nm. It is estimated that optically, the discontinuous metal layer behaves as an effective layer thickness of 2.6 nm. The deposition of the discontinuous metallic layer on zinc stanate instead of zinc oxide seems Petition 870190035436, of 12/12/2019, p. 29/81 25/68 increase the visible light absorbency of the coating, for example, the discontinuous metallic layer. [0037] A second layer of preparer 60 can be deposited on the second layer of metal 58. The second layer of preparer 60 can be as described above with reference to the first layer of preparer 48. According to an example, the second layer of preparator can be a nickel and chromium alloy (such as Inconel) which has a thickness in the range of 5  to 50 Â, for example, 10  to 25 Â, for example, 15  to 25 Â, for example, 15  to 22 Â. Since the absorbance of the subcritical material depends at least partially on the boundary conditions, different preparers (for example, which have different refractive indices) can provide the coating with different absorbance spectra and, therefore, with different colors. [0038] A third dielectric layer 62 can be deposited on the second metallic layer 58 (for example, on the second film primer 60). The third dielectric layer 62 may also include one or more layers of metal oxide or that contain metal alloy oxide, such as discussed above with respect to the first and second dielectric layers 40, 50. According to one example, the third dielectric layer 62 is comprised of a layer of several films similarly to the second dielectric layer 50. For example, the third dielectric layer 62 may include a first layer of metal oxide 64, for example, a layer of zinc oxide, a second layer containing alloy oxide Petition 870190035436, of 12/12/2019, p. 30/81 26/68 metal 66, for example, a layer of zinc stannate deposited on the layer of zinc oxide 64, and an optional third metal oxide layer 68, for example, another layer of zinc oxide, deposited on the layer of zinc stanate 66. According to an example, the two layers of zinc oxide 64, 68 are present and each has a thickness in the range of 50  to 200 Â, such as 75  to 150 Â, as 80  to 150 Â, it is like 95  to 120 Â. The metal oxide layer 66 can be provided with a thickness ranging from 100  to 800 Â, for example, 200  to 700 Â, for example, 300  to 600 Â, for example, 380  to 500 Â, for example, 380  to 450 Â. [0039] According to an example, the total thickness of the third dielectric layer 62 (for example, the combined thicknesses of the zinc oxide and zinc stanate layers) is in the range of 200  to 1000 THE for example, 400  up to 900 Â, per example, 500 THE up until 900 Â, for example, 650  up to 800 Â, for example, 690 THE up until 720 THE [0040] A third heat and / or radiation reflective metallic layer 70 is deposited on the third dielectric layer 62. The third reflective layer 70 can be of any of the materials discussed above with respect to the first reflective layer. According to a non-limiting example, the third layer reflects log 70 includes silver and is gifted of a thickness situated in the range of 25  up 300 Â, for example , 50  to 300 Â, per example 50  up 200 Â, such like 70  up 151 Â, such how 100  up 150 Â, such like 137  to 150 Â. THE third Petition 870190035436, of 12/12/2019, p. 31/81 27/68 The metallic layer is comprised of a continuous layer. [0041] The third layer of preparator 72 is located on the third reflective layer 70. The third layer of preparator 72 can be as described above with respect to the first or second layers of preparer. According to a non-limiting example, the third layer of preparer is comprised of titanium and has a thickness in the range of 5  to 50 Â, for example, 10  to 33 Â, for example, 20  to 30  . [0042] A fourth dielectric layer 74 is located on the third reflective layer (for example, on the third layer of preparator 72). The fourth dielectric layer 74 can be comprised of one or more layers of metal oxide or that contains metal alloy oxide, such as those discussed above with respect to the first, second, or third dielectric layers 40, 50, 62. According to a non-limiting example, the fourth dielectric layer 74 is comprised of a layer of several films which is provided with a first layer of metal oxide 76, for example, a layer of zinc oxide, deposited on the third film of preparator 72, and a second layer of metal alloy oxide 78, for example, the layer of zinc stannate, deposited on the layer of zinc oxide 76. According to a non-limiting embodiment, the layer of zinc oxide 76 can be provided with a thickness in the range of 25  to 200 Â, such as 50  to 150 Â, such as 60  to 100 Â, such as 80  to 90 Â. The layer of zinc stanate 78 can be provided with a thickness ranging from 25 A to 500 Â, for example, 50  to 500 Â, for example Petition 870190035436, of 12/12/2019, p. 32/81 28/68 plo, 100  to 400 Â, for example, 150  to 300 Â, for example, 150  to 200 Â, for example, 170  to 190 Â. [0043] According to a non-limiting example, the total thickness of the fourth dielectric layer 74 (for example, the combined thicknesses of the zinc oxide and zinc stanate layers) is in the range of 100  to 800 Â, for example for example, 200  to 600 Â, for example, 250  to 400 Â, for example, 250  to 270 Â. [0044] A cover 80 can be located on the fourth dielectric layer 74. Cover 80 can help protect the underlying coating layers from mechanical or chemical attack. The cover 80 can be, for example, a layer of metal oxide or metal nitride. For example, cover 80 may consist of titania which has a thickness ranging from 10  to 100 Â, such as 20  to 80 Â, such as 30  to 50 Â, such as 30  to 45  . Other materials useful for the coating include other oxides, such as silica, alumina, or a mixture of silica and alumina. [0045] According to a non-limiting embodiment, the transparency 10 of the invention is endowed with a percentage reflectance (% R) of visible light that varies from surface No. 1 in the range of 5% to 50%, such as 20% to 40%, such as 25% to 30%. Transparency 10 is provided with a visible light transmission which is greater than 20%, such as greater than 30%, as well as greater than 40%. The transparency has a solar heat gain coefficient (SHGC) of less than 0.3, such as less than 0.27, such as less than 0.25. Petition 870190035436, of 12/12/2019, p. 33/81 29/68 [0046] Unlike the previous articles, the layer coated with coating 30 can be tempered or heat treated without adversely affecting the performance characteristics of the article or producing fog. Also, the article of the invention is provided with a neutral or moderate reflected color, such as blue or greenish blue, both in the reflection and in the transmission. [0047] It is believed that the absence of fog during heating is due to the islanded structure of the discontinuous intermediate metallic layer. Figure 3 shows a side view of the subcritical metallic layer 90, which is provided with regions of discontinuous coating 91 formed in the dielectric layer 92 and covered by a layer of preparer 94. The thickness of the subcritical metal makes the material of metal forms discontinuous regions or islets of metal or metal oxide in the dielectric layer 92. When the preparer layer is applied over the subcritical metal layer, the material of the preparer layer covers the islets and can also extend in the intervals between islets adjacent to the subcritical metal and contact the underlying layer 92. [0048] Coating 30 of the invention provides several advantages over known coatings. For example, the subcritical metallic layer increases the visible light absorbency of the coating, making the coated article darker. The combination of the subcritical metallic layer with selected thicknesses of the dielectric layers can provide the coated article with an asymmetric reflectance. The color of the article can be tuned to the transmission by changing the preparation (s) Petition 870190035436, of 12/12/2019, p. 34/81 30/68 pain (s) used in the coating. Also, the coating of the invention is capable of being heat treated without introducing mist. [0049] It should be understood that the coating 30 described above is not limiting the invention. For example, it is not necessary for the subcritical metallic layer to be the second metallic (intermediate) layer in the stack. The subcritical metallic layer can be placed anywhere in the coating stack. Likewise, for piles of linings that are provided with a plurality of layers of linings, more than one of the metallic layers may be a subcritical metallic layer. [0050] Although the above example includes two continuous metal layers and one discontinuous metal layer, it should be understood that this is only a non-limiting example. In the broad practice of the invention, the coating of the invention may include multiple continuous metallic layers and multiple discontinuous metallic layers. For example, the coated article may include a single subcritical metallic layer located between two dielectric layers. Or, the coating may include 3 or more metallic layers, such as 4 or more metallic layers, such as 5 or more metallic layers, such as 6 or more metallic layers, with at least one of the metallic layers being the subcritical metallic layer. Titanium Preparer [0051] Another exemplary coating 130 of the invention is illustrated in Figure 4. This exemplary coating 130 includes a base layer or Petition 870190035436, of 12/12/2019, p. 35/81 31/68 first dielectric layer 140 deposited on at least a part of the main surface of a substrate (for example, surface 16 No. 2 of the first layer 12). The first dielectric layer 140 may be similar to the first dielectric layer 40 described above. For example, the first dielectric layer 140 may be a single layer or may comprise more than one film of anti-reflective materials and / or dielectric materials, such as, but not limited to, metal oxides, oxides of metal alloys, nitrides, oxynitrides, or mixtures thereof. The first dielectric layer 140 can be transparent to visible light. Examples of metal oxides that are suitable for the first dielectric layer 140 include oxides of titanium, hafnium, zirconium, niobium, zinc, bismuth, lead, indium, tin, as well as mixtures thereof. These metal oxides can be endowed with small amounts of other materials, such as manganese in bismuth oxide, tin in indium oxide, and the like. In addition, oxides of metal alloys or mixtures of metals can be used, such as oxides containing zinc and tin (for example, zinc stanate, defined below), oxides of tin and indium alloys, silicon nitrides, silicon nitrides and aluminum, or aluminum nitrides. In addition, inducible metal oxides, such as antimony or indium-induced tin oxides or nickel or boron-induced silicon oxides, can be used. The first dielectric layer 140 may be a substantially single phase film, such as a metal alloy oxide film, for example, zinc stanate, or it may be a Petition 870190035436, of 12/12/2019, p. 36/81 32/68 mixture of phases composed of zinc and tin oxides or can be composed of a plurality of films. [0052] For example, the first dielectric layer 140 (be it a single film layer or several films) can be provided with a thickness ranging from 100  to 600 Â, such as 100  to 500 Â, such as such as 100  to 350 Â, such as 150  to 300 Â, such as 200  to 250 Â, such as 210  to 220 Â. [0053] The first dielectric layer 140 may comprise a structure of several films which is provided with a first film 142, for example, a metal alloy oxide film, deposited on at least part of a substrate (such as the main surface inner layer 16 of the first layer 12) and a second film 144, for example, a metal oxide film or mixture of oxides, deposited on the first metal oxide film 142. According to a non-limiting embodiment, the first film 142 can be zinc stanate. [0054] For example, the first film 142 may be zinc stannate and the second film 144 may be zinc oxide (e.g. 90% by weight zinc oxide and 10% by weight tin oxide) . For example, the first film 142 may comprise zinc stanate which is provided with a thickness in the range of 50  to 600 Â, such as 50  to 500 Â, such as 75 A to 350 Â, such as 100  to 250  Â, such as 100  to 200 Â, as 100A to 150 Â, such as 140  to 150 Â. [0055] The second film 144 may comprise Petition 870190035436, of 12/12/2019, p. 37/81 33/68 zinc oxide which has a thickness in the range of 50  to 200 Â, such as 50  to 150 Â, such as 70  to 100 Â. [0056] A first heat and / or radiation reflective metallic layer 146 can be deposited on the first dielectric layer 140. The first reflective layer 146 can include a reflective metal, such as, but not limited to, gold, copper, palladium, silver metallic or mixtures, alloys, or combinations thereof. According to one embodiment, the first reflective layer 46 comprises a layer of metallic silver which has a thickness ranging from 25 A to 300 Â, for example, 50  to 300 Â, for example, 50  to 250  , for example, 50  to 200 Â, such as 70  to 200 Â, such as 100  to 200 Â, such as 120  to 180 Â. [0057] A first layer of preparator 148 is located on the first reflective layer 146. The first layer of preparator 148 can be a single film layer or several films. The first layer of preparator 148 can include an oxygen capture material that can be sacrificed during the deposition process to prevent degradation or oxidation of the first reflective layer 146 during the cathodic sublimation process or subsequent heating processes. The first layer of preparer 148 can also absorb at least part of the electromagnetic radiation, such as visible light, which passes through the coating 130. Examples of useful materials for the first layer of preparer 148 include titanium, Inconel, Stellite®, as well like their mixtures. For example, the first layer of Petition 870190035436, of 12/12/2019, p. 38/81 34/68 Preparer 148 can be provided with thicknesses ranging from 5 A to 50 Â, for example, 10  to 40 Â, for example, 20  to 40 Â, for example, 20  to 30 Â. According to an example, the first preparer 148 is comprised of titanium. [0058] A second dielectric layer 150 is located on the first reflective layer 146 (for example, on the first layer of preparator 48). The second dielectric layer 150 may comprise one or more metal oxide films or that contains metal oxide alloy, such as those described above with respect to the first dielectric layer 140. For example, the second dielectric layer 150 may include a first film of metal oxide 152, for example, a film of zinc oxide, deposited on the first film of preparer 148 and a second film of metal alloy oxide 154, for example, a film of zinc stanate (Zn2SnO4), deposited on the first zinc oxide film 152. A third optional metal oxide film 156, for example, another zinc oxide layer, can be deposited on the zinc stannate layer. [0059] The second dielectric layer 150 can be provided with a total thickness (for example, the combined thicknesses of the layers if more than one layer is present) is in the range of 50  to 1000 Â, for example, 50  up to 500 Â, for example, 100  to 400 Â, for example, 200  to 400 Â, for example, 300  to 400 Â, for example, 350  to 400 Â, for example, 350  to 370 Â. [0060] For example, for a layer of several Petition 870190035436, of 12/12/2019, p. 39/81 35/68 films, zinc oxide film 152 (and optional second zinc oxide film 156, if present) may have a thickness in the range of 10  to 200 Â, for example, 50  to 200 Â, for example, 50  to 150 Â, for example, 50  to 85 Â.

When the target is subjected to cathodic sublimation, for example, in an oxygen-containing atmosphere, the first material oxidizes and forms a dielectric matrix phase and the second material becomes contained within the phase, such as in the form of metal nano-particles. The composite nano layer 382 can be adjusted by appropriate selection of the reaction gas, cathodic sublimation voltage, and the like, to form a composite nano layer of a desired thickness. This nano composite layer 382 which is provided with metal particles 386 embedded within the first material 384 can better withstand the high temperatures associated with heat treatment or tempering than coatings with continuous metal films. Small Band Interval Semiconductor Materials As Absorbent Layer [00105] In some applications, it may be desirable to modify a particular transmitted color without affecting the solar control performance of the coating. One way to achieve this will be through the use of the integration of a semiconductor material within a solar control coating that has a band gap limit in the visible region of the electromagnetic spectrum. As will be appreciated by one skilled in the art, at the limit of a semiconductor band interval, radiation of shorter wavelength is absorbed through the semiconductor material while energy of longer wavelength is transmitted through the material. That is, the material is transparent to radiation above the bandwidth limit. Through the selection of a material that is Petition 870190035436, of 12/12/2019, p. 60/81 56/68 with a bandwidth limit in the visible region, it is possible to select the wavelength of electromagnetic radiation that is absorbed or that passes through the semiconductor material. Through the use of semiconductor materials with small band intervals, such as, but not limited to, germanium or germanium based alloys, the absorption limit can be placed close to the long wavelength side of the visible spectrum . In this way, the optical transmission can be reduced without absorption near or far from infrared radiation, reducing unnecessary heating of the glass during absorption to a minimum. This semiconductor material can be placed within a conventional solar control coating, such as between two layers of silver, above a layer of silver, below a layer of silver, or anywhere within the stack. [00106] The following Examples illustrate various embodiments of the invention. However, it should be understood that the invention is not limited to these specific embodiments. EXAMPLES [00107] In the examples set out below, Rf refers to the lateral reflectance of the film, Rg refers to the lateral reflectance of the glass, T refers to the transmittance through the article, Rg60 refers to the lateral reflectance of the glass under at an angle of 60 degrees, Rx refers to the exterior reflectance of a standard IGU from surface No. 1, Rint refers to the reflectance of the IGU from the inner surface (No. 4), VLT refers to the transmission of visible light, and SHGC refers to Petition 870190035436, of 12/12/2019, p. 61/81 57/68 to the solar heat gain coefficient. A standard IGU ”is provided with an outer layer of glass 6 mm thick, an inner layer of glass 6 mm, a gap of 1.27 cm (0.5 inch) filled with air, with the coating on the surface N °. 2. S.C. means of subcritical thickness (i.e., the layer was not a continuous layer, but was deposited to form discontinuous coating regions). [00108] In the following examples, hot treated ”means that the coated substrate was heated in a box oven to a temperature of 640 ° C (1,185 ° F) to simulate quenching and then air-cooled to room temperature before optical characteristics to be measured. [00109] The color coordinates a *, b *, and L * are those of the conventional CIE (1931) and CIELAB systems that will be understood by those normally versed in the technique. [00110] In order to model the response of the subcritical layer structure to electromagnetic radiation so that the optical properties of the entire stack can be optimized and controlled, the subcritical layer can be modeled in the form of two idealized layers. These idealized layers are endowed with uniform optical properties (that is, refractive index (n) and extinction coefficient (k)) through their thickness, just like the other layers in the pile. Thus, the thicknesses referred to in the examples are the thicknesses of these idealized layers and are significant in the context of calculating the optical response of a given coating pile that Petition 870190035436, of 12/12/2019, p. 62/81 58/68 contains these layers. [00111] Likewise, the thickness values associated with the subcritical layers in the examples and layouts below are effective thicknesses "calculated based on a reference coating speed that is slower than the current coating speed of the commercial coating machine . For example, a layer of silver is applied to a substrate at the same coating rate as a commercial coating, but at a reduced line speed (reference coating speed) compared to the commercial coating. The thickness of the coating deposited under the reference coating speed is measured and then the effective thickness ”for a coating deposited under the same coating speed, but under the faster line speed of the commercial coating is extrapolated. For example, if a particular coating rate provides a silver coating of 250 Ã… under the reference coating speed which is one tenth of the line speed of the commercial coating, then the effective thickness ”of the silver layer under the same coating rate. coating, but under the line speed of the commercial coating (ie ten times faster than the reference coating run) is extrapolated to be 25  (that is, one tenth of the thickness). However, as will be appreciated, the silver layer under this effective thickness (below the subcritical thickness) will not be a continuous layer, but instead it will be a discontinuous layer that is provided with discontinuous regions of silver material.
