Descriptive Report of the Invention Patent for BRONZE COLORED COATED ARTICLE AND BRONZE INSULATING GLASS WINDOW UNIT. [001] Some examples of embodiments of the present invention relate to a coated article, including a glass substrate supporting a low E coating, wherein the low E coating includes at least one absorption layer for the purpose of control the color and / or reflectivity of the coated article. The coated article can be used in an insulating glass (IG) window unit in certain exemplary modalities. BACKGROUND OF THE INVENTION [002] Coated articles are known in the art for use in window applications such as insulating glass (IG) window units, vehicle windows, and / or the like. It is known that in certain cases, it may be desirable for heat treatment (for example, thermal tempering, heat bending and / or heat strengthening) such coated articles for the purpose of tempering, bending, or the like. [003] Insulating glass (IG) windows are known in the art. Conventional IG window units include at least one first and second glass substrate (one of which may have a solar control coating on an interior surface of the same) which are coupled to each other via at least one seal (s ) or a spacer (s). The resulting space or gap between the glass substrates may or may not be filled with gas and / or evacuated to low pressure in different cases. Some units of the IG window are tempered. The thermal quenching of the glass substrates for such IG units typically requires heating the glass substrates to a temperature (s) of at least about 580 degrees C, for a sufficient period of time to allow thermal quenching. Petition 870190037510, of 04/18/2019, p. 6/25 2/55 mica. Monolithic architectural windows for use in houses or buildings are also known in the art, and may include a coating supported by a glass substrate. Fixing windows in houses can be made of glass sheets. Such monolithic windows can also optionally be thermally tempered for safety purposes. Heat treatment (e.g., heat quenching) of coated articles typically requires the use of temperature (s) of at least 580 ° C, more preferably at least about 600 degrees C and even more preferably at least 620 ° C . [004] In certain situations, designers of coated articles often strive for a combination of desirable visible transmission, desirable color, low reflectance, low emissivity (or emissivity), and low surface resistance (R s ). The characteristics of the low resistance and low emissivity sheet (Low E) allow these coated articles to block a significant amount of IR radiation, in such a way that it reduces, for example, undesirable heating inside the vehicle or building. Coated article designers also seek to have particular color appearances (for example, when viewed from the outside of a building or vehicle on which the coated article is mounted) and / or low visible reflectance. Typically, layers reflecting low IR (for example, silver based layers), while enabling IR blocking, cause visible reflectance to increase. Thus, in the past, it has been difficult to achieve a combination of good IR blockage and at the same time has reduced or relatively lowered visible reflectance. [005] In view of the above, it will be evident to those who are versed in the technique that there is a need in 3/55 technical with respect to an article coated with one or more of the desirable visible transmission, the desirable color, the low reflectance, the low emissivity (or emissivity), and / or the low surface resistance (Rs). In certain exemplary embodiments, it will be apparent that there is a need in the art with regard to a coated article (for example, for use in a GI window unit), which can achieve a desirable color combination (for example, desired values a * and / or b *), very low values of visible reflectance, low emissivity and / or surface resistance, and desired visible transmission. BRIEF SUMMARY OF THE INVENTION [006] A coated article, including a low E coating supported by means of a substrate (for example, the glass substrate) is provided in certain exemplary embodiments of the present invention. In certain exemplary embodiments, the coated article has one or more of the desirable visible transmission, the desirable color, the low reflectance, the low emissivity (or emittance), and / or the low surface resistance (R s ). In certain exemplary embodiments, the coated article (for example, for use in an IG window unit) can achieve a desirable color combination (for example, desired reflector values a * and / or * b), very low visible reflectance, Low emissivity and / or surface resistance, and desired visible transmission. As used in the present invention, the term a coated article can be or include a monolithic coated article and / or an IG unit. [007] In certain exemplary embodiments of the present invention, a layer of color absorption and / or adjustment of reflectivity of the low E coating is included in order to allow the coloring and / or reflectivity of the coating (and coated article) will be selectively controlled. The coated article may have a 4/55 color bronze, green, neutral, shade of blue, or other colors in different exemplary modalities. The visible reflectance of the glass side (or exterior) of the coated article can advantageously be reduced. In certain exemplary embodiments, the absorption / breaker layer is included for the purpose of forming a coated article with color and / or reflectivity properties that are more easily controllable / tunable, and which may have reduced reflectance of the glass side (Yg and / or Rout). Advantageously, the inclusion of the color absorbent layer and / or reflectivity adjustment between the dielectric layers, together with the manipulation of thicknesses of other layer (s) present in the low E coating, was found with the purpose of reduce the reflectance of the glass side and produce desirable tunable matrices such as bronze, green, neutral, and blue, while at the same time allowing a relatively thick layer that reflects IR to be used, if desired. In other words, the inclusion of a color absorbent layer and / or reflectivity adjustment was found with the purpose of providing articles coated with tunable bronze, green, neutral, and / or blue colors that indicate that the desired color can be obtained, and / or that allows an acceptably low combination of visible reflectance and Low emissivity and / or surface resistance. [008] The side (or exterior) color of glass (for example, the values a * g and / or b * g ) can be optimized based on the thickness and materials / composition of the individual layers of the low E coating, in certain exemplary modalities, which is advantageous from aesthetic and architectural perspectives. In addition, good solar properties (for example, low surface resistance and acceptable visible transmission) are also possible in certain exemplary embodiments of the coatings described in the present invention. Note that the a * g and b * g color values of the present invention 5/55 tion refer to the coloring of the reflective side glass, as seen from the side of a monolithic coated glass article or from the side of an IG window unit adapted to the exterior face of the building or structure.

[0014] Figure 2 is a sectional view of the unit of an insulating glass (IG), which can include the coated article of any one of Figures 1 or 3 to 5. [0015] Figures 3 (a) and 3 (b) are seen in section of coated articles in accordance with other exemplary embodiments of the present invention. [0016] Figures 4 (a), 4 (b), and 4 (c) are seen in section of coated articles according to the additional exemplary embodiments of the present invention. [0017] Figures 5 (a), 5 (b), and 5 (c) are seen in section of coated articles according to additional exemplary embodiments of the present invention. DETAILED DESCRIPTION OF THE INVENTION [0018] Articles coated in accordance with the exemplary embodiments of the present invention can be used in applications such as IG window units, vehicle windows, monolithic architectural windows, residential windows and / or any other suitable application, including substrates single or multiple glass. The same reference numbers in the different figures refer to similar parts / layers of the present invention. [0019] The surface resistance (R s ) is indicative of emissivity or emission. Low surface resistance is achieved in certain exemplary embodiments of the present invention, in combination with the desired color and reflectance values, due to the presence of the absorbent layer (s). In certain exemplary embodiments of the present invention, a coated article comprises a surface resistance (Rs) of not more than about 10.0 ohms / square, more preferably not more than about 9.0 ohms / square, even more preferably not more than about 5.0 8/55 ohms / square, even more preferably not more than about 4.0 ohms / square, and, eventually, or more preferably less than or equal to about 3.5 ohms / square. These surface resistance values, applicable to any embodiment of the present invention, can be before and / or after the optional heat treatment, such as the thermal quenching of the coated article. In certain exemplary embodiments, a surface resistance of no more than 3.0 ohms / square may be possible. Low surface resistance values are indicative of low emissivity. [0020] In certain exemplary embodiments of the present invention, a low E coating comprises a single IR reflecting layer comprising silver and / or gold, although the present invention is not so limited in all cases. While other numbers of IR-reflecting layers can sometimes be provided, the use of one is preferable, in certain cases, where low emission can be achieved and more of such layers are not needed, making coatings easier and easier. profitable for manufacturing and less likely to produce problems. [0021] In certain exemplary embodiments of the present invention (for example, see figures 1 to 5), the coated articles may or may not be heat treated (for example, thermally tempered). In certain exemplary embodiments (for example, see figures 1 to 5), coated articles may have an emissivity (normal and / or hemispherical) of no more than about 0.12, 0.11, and / or 0 , 10, more preferably not more than about 0.06, even more preferably, not more than about 0.05, and more preferably not more than about 0.04 (e.g., 0.037). In certain exemplary modalities, after heat treatment and, as measured in monolithic form, articles Coated 9/55 (for example, see figures 1 to 5), before and / or after HT are able to carry out a visible transmission (Ill. C, 2 degrees) of up to about 60%, more preferably up to about 50%, and more preferably not more than 45% or 40%. In certain exemplary embodiments, the coated article has a visible transmission of about 20 to 50%, more preferably about 30 to 48%, in a monolithic and / or IG unit. [0022] The Solar factor (SF, or g-value), calculated according to the standard EN 410, refers to a relationship between the total energy that enters an environment or similar through a glass pane and the incident solar energy. Thus, it should be noted that the lower SF values are indicative of good sun protection against undesirable heating of environments or similar protected through windows / glazing. For example, a low SF value is indicative of a coated article (for example, IG unit such as double or triple glazing) that is able to maintain a relatively cool environment in the summer months, during hot ambient conditions. [0023] When low SF values are typically desirable for coated articles, such as IG window units, achieving lower SF values usually comes at the expense of visible transmission and / or coloring. It is often desirable, but difficult, to obtain a combination of an acceptable visible transmission, the coloration of the desirable side glass, and a low SF value for a coated article, such as an IG window unit or the like. In this regard, the relationship between visible transmission (T vis ) and SF is sometimes referred to as selectivity. In other words, the term selectivity of a coated article is defined by T vis / SF. High selectivity values are often desirable because they combine high or desirable visible transmission with a low SF value that is indicative of IR block. 10/55 [0024] In certain exemplary embodiments of the present invention, a coated article is provided with a stack of layers that can allow the coated article to achieve one or more of a good selectivity (T vis / SF), an acceptable solar factor (FS ), and / or Low emissivity. One, two, three or all of these characteristics can be achieved from different modalities of the present invention (for example, see figures 1 to 5). When a good selectivity (T vis / SF) is obtained, a higher visible transmission ratio (Tvis) of the solar factor (SF) is provided, which will be appreciated by those who are versed in the technique. [0025] In certain exemplary embodiments of the present invention (for example, see figures 1 to 5), a coated article such as an IG window unit comprises a selectivity value (T vis / SF) of at least about 1 , 12 or 1.20, more preferably at least about 1.30, even more preferably at least about 1.35, and, in certain cases, at least about 1.40 or 1.43. In certain exemplary embodiments of the present invention, good selectivity is achieved without sacrificing SF values. In other words, good selectivity values are obtained in combination with very low SF values. In certain exemplary embodiments of the present invention, the coated articles may comprise a good selectivity value, in combination with an SF of no more than 31, and more preferably, an SF of no more than about 30, even more preferably , an SF of no more than about 29, and even more preferably, an SF of no more than about 28. This allows the coated articles and / or IG window units, for example, to perform the desirable visible transmission, while at the same time, blocking significant unwanted radiation (eg, IR) from reaching the construction of the interior or the like. 11/55 [0026] In certain exemplary embodiments of the present invention, articles coated with a single IR reflecting layer are capable of having a reduced lateral glass reflectance. In certain exemplary embodiments, before and / or after HT, the coated articles, such as the IG window units according to the particular exemplary embodiments of the present invention, have a reflectance of the side of the glass (Y) of no more than about 16%, more preferably about 15% or less, even more preferably about 14% or less, while maintaining a desirable color. [0027] The term heat treatment, as used in the present invention means heating the article to a sufficient temperature in order to achieve thermal quenching, heat bending, and / or thermal reinforcement of the inclusive glass article. This definition includes, for example, heating a coated article in an oven or furnace to a temperature of at least about 580 degrees C, more preferably at least about 600 degrees C, for a period sufficient to allow quenching, bending and / or thermal reinforcement. In certain cases, HT can be at least about 4 or 5 minutes. The coated article and / or the IG unit may or may not be heat treated by different modalities of the present invention. [0028] Figure 1 is a cross-sectional side view of an article coated according to an exemplary non-limiting embodiment of the present invention. The coated article includes a substrate (for example, transparent, green, bronze or blue-green glass substrate about 1.0 to 10.0 mm thick, and the low E coating (or layer system) 30 provided on the substrate in a direct or indirect way The coating (or layer system) 30 includes, for example: the lower dielectric layer 3 which can be silicon nitride (for example, SixNy and / or Si3N4), oxide oxinitride silicon and / 12/55 or silicon, in different modalities of the present invention, absorbent / color switch and / or adjustable metallic or substantially metallic reflectivity 4 (for example, from or including one or more of Ni, Cr, NiCr, Nb, Zr, NbZr, Si, Ti, Zn, Sn, Cu, Al, V, Mn, Mo, Pd, Ta, W, In, InSn, and / or stainless steel, and / or a mixture (alloy) of the same , the foregoing materials may be partially and / or fully oxidized and / or nitride), dielectric layer 5 which may be totally or partially in silicon nitride (eg Si x N y and / or Si 3 N 4 ), oxide silicon and / or silicon oxinitride, in different embodiments of the present invention (and which may be of a substantially similar material or the same and / or composition, such as layer 3 in certain embodiments), the lower contact layer 6 (which contacts the lower layer that reflects IR 7), the conductor and preferably the layer that reflects the metallic or substantially metallic infrared (IR) 7, upper contact layer 8, dielectric layer 9, the color absorbent and / or reflectivity adjustment layer 10 (for example, from or including one or more of Ni, Cr, NiCr, Nb, Zr, NbZr, Si, Ti, Zn, Sn, Cu, Al, V, Mn, Mo, Pd, Ta, W, In, InSn, and / or stainless steel, and / or a mixture (alloy) thereof; the above materials can be partial and / or fully oxidized and / or nitride), dielectric layer 11, and a coating layer 12 like layers 3 and 5, layers 9 and 11 can be of the same material and / or the composition in certain exemplary embodiments, so that the dielectric layers are divided by means of the intervening absorbent layer. Note that all previous layers may or may not be included in the low E 30 coating of certain exemplary modalities. In particular, only one of the color-absorbing layers and / or the reflectivity adjustment 4, 10 may be present in some modalities (for example, see Figures 3 (a) and 3 (b)), or both may be present (for example, see Figure 1, Figure 4 (c), and 13/55 in Figure 5 (c)). The contact layers 6 and 8 of each contact of the layer that reflects IR 7 (for example, the base layer in Ag). The aforementioned layers 3 to 12 comprise Low E (i.e., Low emissivity) of coating 30 which is provided on the glass or plastic substrate 1. Additional layers can also be provided. [0029] In monolithic examples, the coated article includes only a glass substrate 1, as illustrated in figure 1. However, the monolithic coated articles in this document can be used in devices such as vehicle windshields, units IG laminated window frames, and the like. [0030] Figure 2 is a cross-sectional view of an IG window unit, showing that the coating 30 can be provided on the inner side of the glass substrate 1. However, the present invention is not limited in this way, and it is noted that the coating 30 can be provided on both glass substrates, preferably on the side of the substrate closest to the opening 17. [0031] As Figure 2 shows, an IG window unit can include two spaced glass substrates 1 and 50. An example of the IG window unit is illustrated and described, for example, in US Patent Document No. 2004/0005467 , the description of which is incorporated by reference into the present invention. An example of the IG window unit may include, for example, the coated glass substrate 40 shown in figure 1 (or any of Figures 3 to 5.) Coupled to another glass substrate 50 via spacer (s), the seal (s) or similar (15), with an opening 17 being defined between them. This opening 17 between substrates with IG unit modalities can in certain cases be filled with a gas such as argon (Ar). An example of the IG unit can comprise a pair of clear glass substrates spaced apart each from about 3 to 4 14/55 mm thick, one of which is coated with a low coating E 30 in the present invention in certain cases, for example, where the space between the substrates can be from about 5 to 30 mm, more preferably from about 10 to 20 mm, and more preferably about 16 mm. In certain embodiments, the coating 30 is provided inside the outermost glass substrate (for example, closer to the outside side) 1, as shown in figure 2. However, in other embodiments, the coating 30 can be provided on the inner surface of one or another substrate facing the opening. An IG unit can also include additional substrate (s), such as three types of glass substrates, in certain cases. [0032] Figures 3 to 5 show the modalities of other examples of the present invention, the coatings of which can be used in connection with figures 1 and / or 2. [0033] It has been found that, advantageously, by including a color absorbent and / or reflectivity adjustment layer (4 and / or 10) of variable thickness for the layer stack mentioned above (for example, see figures 1 to 5) in one or more places can result in desirable optical qualities. More specifically, certain exemplary modalities, by adjusting the thickness of the color absorbent layer (s) and / or the reflectivity adjustment 4 and / or 10, the coloring of the side glass of the coated article (the values from the side of the glass a * g and b * g ) can be tuned to look like a certain color when the window unit is seen from the outside. The absorbent or interruption layer (s) 4 and / or 10 can be conductive (s), in certain instances of examples. Unless otherwise indicated, the values a * g and b * g in the present invention refer to the coloring of the reflective side glass, as seen from the side of a monolith coated glass article 15/55 typical or from the side of an IG window unit adapted to the exterior face of the building or structure. Likewise, the visible reflectance of the side glass (Y) refers to the visible reflection of the side glass, as seen from the side of a monolithic coated glass article or from the side of an adapted IG window unit. the exterior face of the building or structure. [0034] More particularly, in certain exemplary embodiments, including the absorption layer 4, between two dielectric layers 3 and 5 can result in a coated article that has desirable optical qualities. In certain exemplary embodiments, the dielectric layers 3 and 5 comprise the same or substantially similar materials / composition. In fact, in certain exemplary embodiments, a silicone-based layer is divided into two layers, 3 and 5, and a color-absorbing and / or reflectivity adjustment layer is provided between the two dielectric layers. The layers 3 and 5, which can be of different thicknesses, are exemplary modalities. In other embodiments, layers 3 and 5 can be substantially the same thickness. The thickness of layers 3 and 5 can be changed to contribute to the realization of a desirable side color of the glass (for example, the desirable values a * g and * g ). The desirable color of the side of the glass may be different in certain cases. [0035] In certain exemplary embodiments, the color of the glass on the side of the coated article (a * and b * for the glass side) can be bronze, green, neutral, or blue. In this way, a coating 30 can be applied on a transparent glass substrate 1, and the coated article (monolithically, or, when measured as a GI unit), will appear to be colored while still having the desirable characteristics, such as like those of a traditional low E coating, such as a surface resistance (Rs) of no more than 16/55 about 10.0 ohms / square, 9.5 ohms / square, or 9.0 ohms / square, more preferably not more than about 5.0 ohms / square, and even more preferably not more than about 4 , 0 ohms / square, and more preferably less than or equal to about 3.5 ohms / square, before and / or after the optional heat treatment, such as tempering, an emissivity of less than about 0.12, 0 , 11, and / or 0.11, more preferably less than about 0.06, even more preferably less than about 0.05, and more preferably about 0.04 in (for example, 0.032). The resulting coated article may have a reduced glass side (or the outer construction) of reflectance (Y), of 16% or less, more preferably about 14% or less (for example, the IG unit), in certain embodiments specimens, depending, in part, on the desired color. [0036] In certain exemplary embodiments, depending, in part, on the material chosen for the absorbent layer (s) 4 and / or 10, and the thicknesses and materials of layers 3 to 12, of a coating made according to certain exemplary modalities can be supplied on a transparent glass substrate, giving the glass substrate a desired appearance (for example, bronze color) colored. For example, a coating 30 can produce a coated article which, when viewed from the side of the glass (or the exterior construction in Figure 2.), In certain exemplary embodiments, has a shade that is bronze, neutral, green, royal blue , and / or other colors made from a combination of them. [0037] The absorption layer (s) is / are advantageous because the glass side and / or reflectance of the outside side is reduced, and the desirable visible transmission, color and low SF can be achieved without sacrificing surface resistance. For example, and without limitation, it is often more aesthetically pleasing, when a structure such as a building has windows with low side reflectance 17/55 of the glass. Architects may therefore prefer the glass (or exterior) side of visible reflectance to be lower, but may not want to sacrifice surface resistance, color and / or the visible transmission for this purpose. In certain exemplary embodiments, the thickness of the IR 7 reflecting layer (s), which may comprise silver or gold, can be increased. Increasing the thickness of layer 7 can increase the reflectance of the side of the glass, thus, if the reflectance of the side of the glass is reduced by the inclusion of absorbent layer (s) 4 and / or 10, but increased by through the thickening of layer 7, the net change in the glass reflectance side can be minimal or even zero or practically zero. Increasing the thickness of the IR 7 reflecting layer is desirable, as it improves the ability of the IG unit to block / reflect IR radiation, which would reduce the amount of IR radiation entering a building, structure , vehicles, etc., through the window. [0038] In certain exemplary embodiments, layers 3 to 12 are sprayed onto a glass substrate. This can be applied to any of Figures 1 to 5. The electrical discharge target (s) can be flat or cylindrical magnetic rotating targets (not shown) in the exemplary embodiments of the present invention. Metal and / or ceramic targets can be used. [0039] With reference to Figures 1 to 5, the dielectric layers 3 and 5 may comprise silicon nitride, and in other exemplary embodiments, may comprise silicon oxide and / or silicon oxinitride. Layers 3 and 5 can be totally or partially oxidized and / or nitrided. In certain exemplary embodiments, the dielectric layers 3 and 5 may comprise the same or substantially similar material and / or composition. In certain embodiments, the thickness of layers 3 and 5 can be the same or substantially 18/55 similar. In other embodiments, one of the layers 3 and 5 can be thicker than the other layer 3 or 5. The layers 3 and 5 can each be about 70 to 1200 A thick in certain exemplary embodiments. In certain exemplary embodiments, only one of layers 3 and 5 can be present, however, in other embodiments, both layers 3, 5 can be provided. [0040] Layer 4 can be a color absorbent layer and / or reflectivity adjustment in certain exemplary modalities. The absorption layer 4 can be of or include any of the following materials, or a mixture (alloy) of any of the materials: Ni, Cr, NiCr, Nb, Zr, NbZr, Si, Ti, Zn, Sn, Cu , Al, V, Mn, Mo, Pd, Ta, W, In, InSn, and / or stainless steel. The materials can optionally be partially or fully oxidized and / or nitrided. The absorbent layer 4 can preferably comprise or consist essentially of Ni, Cr, NiCr, Nb, Zr, NbZr, and / or oxides and / or nitrides thereof. Layer 4 can be about 10 to 150 µm thick in certain exemplary embodiments, more preferably about 20 to 70 µm thick. However, in other embodiments, layer 4 can be thicker, sometimes significantly, by 150 A. [0041] Still with reference to Figures 1 to 5, the contact layers 6 and 8 can comprise Ni, Cr, and / or NiCr, or oxides thereof, for example, in specific modalities. Other suitable materials can alternatively or can also be used. The contact layers 6 and 8 can be partially or totally oxidized and / or partially or totally nitrided in certain cases of examples. In certain exemplary embodiments, layers 6 and 8 can help protect the layer that reflects IR 7 from becoming oxidized during the deposition of other layers and / or du 19/55 during heat treatment. Other materials can, alternatively, be used in alternative modalities. The contact layers 6 and 8 can each be about 10 to 150 µm thick in certain exemplary embodiments, more preferably from about 10 to 60 µm thick. [0042] Continuing to refer to Figures 1 to 5, the dielectric layers 9 and 11 can comprise or consist essentially of silicon nitride, and in other exemplary embodiments, they can comprise or consist essentially of silicon oxide and / or silicon oxynitride . Layers 9 and 11 can be totally or partially oxidized and / or nitrided. In certain exemplary embodiments, the dielectric layers 9 and 11 may comprise the same or substantially similar material and / or composition. Note that all silicon nitride, silicon oxynitride, and / or silicon oxide layers of the present invention (for example, see 3, 5, 9 and / or 11) can optionally be doped with aluminum (for example example, 1 to 5%), stainless steel, or the like. In certain embodiments, the thickness of the dielectric layers 9 and 11 can be the same or substantially similar. Layers 9 and 11 can each be from about 70 Å to 1200 in certain exemplary embodiments. In certain exemplary embodiments, only one of layers 9 and 11 can be present, however, in other embodiments, both layers can be provided. [0043] The layer 10 can be of a color absorbent layer and / or of reflectivity adjustment in certain exemplary modalities (for example, see figures 1 to 5). With respect to absorption layers 4, 10, a stack of layers may comprise layers 4 and 10, only layer 4, or single layer 10. Layer 10 can be of or include any of the following materials, or of a mixture (alloy) of any of these materials: Ni, Cr, NiCr, Nb, 20/55 Zr, NbZr, Si, Ti, Zn, Sn, Cu, Al, V, Mn, Mo, Pd, Ta, W, In, InSn, and / or stainless steel. The materials can be partially or totally oxidized and / or nitrided. Layer 10 may preferably comprise or consist essentially of Ni, Cr, NiCr, Nb, Zr, NbZr, and / or oxides and / or nitrides thereof. The absorbent layer 10 can be about 10 to 150 µm thick in certain exemplary embodiments. However, in other embodiments, the absorbent layer 10 may be thicker than 150 µm. Layer 10 cannot be included in certain embodiments, or it can be included instead of layer 4, or both layers can be present. [0044] Layer 12 is an optional overcoat. Layer 12 can be provided on top of the layer reflecting IR 7 and more than the dielectric layer (s) 9, 11. Layer 12 may comprise a nitride oxide, and / or zirconium oxinitride and / or aluminum (for example, ZrOx, ZrOxNy and / or AlOxNy) in certain exemplary embodiments of the present invention. [0045] The coated article manufactured according to the above mentioned modalities (for example, see figures 1 to 5) can be used in an IG unit (for example, see figure 2.). The IG unit may or may not be a vacuum IG unit. In other exemplary embodiments, the coated article can be used as a monolithic window unit. [0046] A coated article and / or IG unit made according to the above modalities is advantageous in that it can reduce the reflectance of the glass side due to the absorption properties of the color absorbent layer and / or the reflectivity adjustment (s). In certain exemplary modalities, it may be possible to obtain a better selectivity in a given reflectance of the side of the glass, increasing the thickness that reflects IR (for example, silver-based) of layer 7. A coated article and / or the IG unit made of acor 21/55 with certain exemplary embodiments of the present invention can also improve thermal, mechanical and chemical durability, compared to silver reflective coatings. [0047] Articles coated with neutral, green, blue, gold, bronze, glass, etc. side reflectance colors are possible to be achieved. It has been found that coated articles and / or insulating glass units made in accordance with certain exemplary embodiments of the present invention may have the lower side of the glass (or exterior) reflecting a split silver (or double silver) coating with color of a variety of coated article containing a single layer that reflects IR. [0048] In certain exemplary embodiments, the desired reflectance of the glass side and the transmission color can be combined to a desirable side reflectance color of the film, including a low side reflectance film. The inclusion of layers 4 and / or 10 in a stack of layers Low E allows the color, reflectivity and solar performance of the coated article to be balanced and refined. [0049] Coated articles produced in accordance with the modalities of the present invention are advantageous in that the transparent glass 1 can be provided with a coating 30 that gives the appearance of a stained glass body, but the glass substrate 1 can , in fact, be transparent or substantially transparent in color, by itself. By reducing the glass side / reflectance of the outside side with a color absorbent and / or reflectivity adjustment layer (4 and / or 10), a thick layer that reflects IR 7 is possible. Normally, a thicker layer that reflects IR increases the reflectance of the side of the glass, but the absorbent layer (s) allows for the thicker layer that reflects IR 7, without a significant increase in the reflectance of the glass. side of the glass. 22/55 [0050] The exemplary modalities, with bronze color (for example, reflective color of the side of the glass) are described above - see figures 1 to 5. This section is, in addition to the above in relation to the colored bronze modalities. A bronze tinted coated article can have a visible transmission of about 10 to 55%, more preferably about 20 to 50%, and most preferably, about 30 to 48%.

When the desired shade of a coated article and / or the IG unit is bronze, layers 4 and / or 10 may comprise or consist essentially of Ni and / or Cr. However, a chromium nickel nitride and / or oxynitride can be used for layers 4 and / or 10 as well. Nb, Zr, and / or NbZr can also be used in certain exemplary embodiments for absorption layer 4 and / or 10. An oxide and / or oxynitride of Nb, Zr, and / or NbZr can also be used.

The thickness of layer 7 can be about 100 to 170 A, more preferably about 110 to 160 µm, and more preferably 115 to 155 A. [0051] Layers 9, 10 and / or 11 are optional, in certain modalities. In certain exemplary embodiments, they can be only one of layers 9 and 11, and layer 10 cannot be included. Other embodiments may have all three layers 9, 10, and 11. In different embodiments, layers 9, 10 and / or 11 may be present, and layers 3, 4 and / or 5 may not be present.

Examples and Comparative Examples: Examples 1 to 5: Bronze [00122] A simulation of a dyed bronze article of cladding was carried out. The cathodic deposition of a low E 30 coating, as described in certain exemplary embodiments of the present invention on a 6 mm clear glass substrate was simulated. The simulation pile for a coated tinted bronze article had layers with approximate thicknesses, as listed below: Table 17: Example 1 Layer Thicknesses Layer Glass (1-10 mm thick) Si 3 N 4 (Layer 3) NiCrN x (Layer 4) Si 3 N 4 (Layer 5) NiCrN x (Layer 6) Ag (Layer 7) NiCrN x (Layer 8) Si 3 N 4 (Layer 9) Example 1 (Â) mm clear glass 140  THE 320  THE 130  THE 480  [00123] The following table presents a comparison of the properties (simulated) of the bronze tinted coated article of Example 1 with the absorbent layer, without an absorbent layer as a comparative example.

Example 11 - Neutral [00134] A coated item tinted with neutral was produced. The next layer was sprayed onto a 6 mm class substrate of clear glass. The tinted neutral coated article included layers with approximate thicknesses, as listed below: Table 25: Example 11 Layer Thicknesses Layer Example 11 (A) Glass (1 to 10 mm thick) 6 mm clear glass SÍNN4 (Layer 3) 240 A NiCrN x (Layer 4) 10 A Si3N4 (Layer 5) 190 A NiCrNx (Layer 6) 25 A Ag (Layer 7) 150 A NiCrNx (Layer 8) 25 A Si 3 N 4 (Layer 9) 580 A [00135] Examples of batteries 12 and 13 were made based on layer 11 and other modalities described in the present invention.

The main function 53/55 pal of the included NiCr layer is to reduce transmission and reflectance. Placing this layer between two sinx layers reduces changes in the top layer of the heat treatment. [00139] In Example 15, a NiCr based layer was also placed between two sinx layers to reduce the visible transmission of the side glass and / reflectance on the outside. Making the NiCr layer thicker (for example, 3.4 nm instead of 1.0 nm, or 34 A instead of 10) improves the reflected color of a positive a * (red) and slightly negative b * ( light blue) for a negative a * (green) and a noticeable negative b * (blue). However, the thickness of the NiCr layers based around the silver layer must be reduced in the present modality. [00140] In Example 16, the base NiCr layer is reduced from Example 15, and the thickness of the second silicon nitride layer has been increased. Although the g value can be increased, this battery has good visible transmission and reflectance values on the sides of the glass. Example 17 - Neutral [00141] Another example of a tinted neutral coating is the following pile, with thicknesses in nanometers: ___________ZrO x 4.5 nm____________ ____________Si 3 N x 46.1 nm____________ ____________NiCr 2.0 nm____________ ___________Ag 18 nm___________ ____________NiCr 2.0 nm____________ ____________Si 3 N x 5.0 nm____________ __________NbZrN x 3.4 nm__________ ____________Si 3 N x 9.9 nm______________ of glass__________ [00142] NbZrNx has a refractive index of approximately 2.81 at 550 nm, and k is about 2.12. The g (Solar Factor) value of this cell is approximately 3% higher than that without an absorbent layer, and this cell allows the same visible transmission. Of that 54/55 way, selectivity is greater. Tvis is between 41.5 and 44.5 for surface coated monolithic glass. The reflectance of the glass side is between 19 and 22%, and a * g is between -0.5 and 1.0, and b * g is between -4.0 and -1.0. The U value of this stack is between 1.1 and 1.2. An optimal value of g (Solar Factor) for this battery is 0.28. Example 18 - Blue [00143] A bluish coated article was produced. The next stack was sprayed onto a 6 mm clear grade substrate. The bluish coated article had layers with an approximate thickness of 10 as listed below: Table 29: Example 18 Layer Thicknesses Layer Example 18 (A) Glass (1 to 10 mm thick) 6 mm clear glass Si 3 N4 (Layer 3) 270 A NiCrNx (Layer 4) 12 A Si 3 N4 (Layer 5) 700 A NiCrNx (Layer 6) 25 A Ag (Layer 7) 130 A NiCrNx (Layer 8) 25 A Si3N4 (Layer 9) 430 A [00144] The samples were coated with a zirconium oxide coating to increase mechanical durability. [00145] The bluish cell including the absorbent layer was simulated 15 before the test, and compared to a layer stack that does not contain an absorbent layer.
