    PREAMBLE / TECHNICAL FIELD
    [0001] The present invention generally relates to documents or security elements that comprise a substrate and at least a first dynamic effect feature provided on the substrate that includes a dynamic effect component that is responsive to the lighting stimulus of a length of selected excitation wave or wavelength band (particularly, but not limited to, ultraviolet radiation) to produce an optical spectral response, such an optical spectral response changes dynamically over an observable period of time between appearances of multiple colors after and while being subjected to the enlightenment stimulus. BACKGROUND OF THE INVENTION
    [0002] Dynamic effect components (or pigments), hereinafter referred to as “DEPs” (Dynamic Effect Pigments), belong to a class of components that respond to incident excitation light exhibiting more than one optical color appearance under uniform illumination and continuous with electromagnetic energy. In other words, the optical spectral response of such components is not constant over time, but changes from one color appearance to at least a second appearance of a different color, typically over an observable period of time of a few seconds. Such DEPs are particularly discussed and disclosed in International Application No. WO 2007/005354 A2 and Patent Publication No. US 2006/0237541 A1, the content of which is incorporated herein by reference in its entirety for reference.
    [0003] A particular subclass of DEPs are self-modulating self-modulating fluorescent pigments (self-modulating) or SMF pigments (AMF), that is, pigment components that produce fluorescence upon exposure to incident excitation light and whose fluorescent response is modulated over the time while being subjected to incident excitation light. SMF pigments can, in particular, be based on an appropriate combination and arrangement of fluorescent dyes and photochromic dyes, in which the photochromic dyes gradually modulate the fluorescence produced by the fluorescent dyes as the photochromic dyes are being activated by the incident excitation light.
    [0004] DEPs can also be based on suitable combinations of fluorescent and / or photochromic dyes with different optical spectral responses and / or response times. Similarly, an optical spectral response of dynamic change under continuous steady state exposure to incident electromagnetic radiation can be created by suitable combinations of different photochromic dyes that exhibit different properties, particularly, different response times.
    [0005] DEPs can be printed, transferred, applied or otherwise supplied on or within a substrate. Suitable printing processes (particularly relief printing, offset printing and screen printing, such printing processes are typically used in the security printing industry), application / transfer processes (such as hot stamping techniques or printing) cold) and incorporation processes (such as used in the context of the manufacture of cotton paper substrates) are known for themselves in the art and can be used to apply DEPs.
    [0006] In the context of the present invention, the term "security element" designates particularly any element that can be produced in a manner suitable for the subsequent provision on or within the security document substrates, including transfer elements for transfer to substrates, such as transferable metal sheets or plasters (similar to so-called Optically Variable Devices or OVDs, as used for application in security documents such as bank notes) and embeddable elements for incorporation into substrates during their manufacture, such as wires , embeddable fibers or platelets (as commonly used for the production of security documents such as bank notes).
    [0007] The term “security document” means any document that has a security value including, but not limited to, bank notes, stamps, passports and similar identification documents, driver's licenses, visas, stock certificates, security labels. brand protection, service seals, etc.
    [0008] The present invention is directed to various applications or paradigms of use, exploring in an innovative way the properties of DEPs as a security feature for security elements or documents, particularly for the purpose of authenticating such elements or security documents. SUMMARY OF THE INVENTION
    [0009] A general objective of the invention is to provide a security element or security document comprising a substrate and a dynamic effect feature provided on the substrate that includes at least one dynamic effect component as discussed above, which at least one component of Dynamic effect is exploited, in combination with one or more additional components, to produce a feature or pattern whose appearance changes dynamically over time in response to incident electromagnetic radiation in a way that is readily recognizable by lambda users.
    [0010] More specifically, an objective of the invention is to provide such a security element or security document that can be easily identified and authenticated without needing complex authentication tools in addition to a reasonably simple lighting source, that is, a security feature usable as a so-called “level two security feature”.
    [0011] These objectives are achieved thanks to documents or security elements as defined in the attached claims.
    [0012] Consequently, a document or security element is provided that comprises a substrate and at least a first dynamic effect feature provided on the substrate that includes a dynamic effect component that is responsive to the lighting stimulus of a selected excitation wavelength. or wavelength band to produce an optical spectral response, such an optical spectral response changes dynamically over an observable period of time between appearances of multiple colors after and while it is subjected to the lighting stimulus, in which the first effect feature dynamic is provided in a region of the substrate that is close to or adjacent to at least one proximity feature provided on the substrate, that at least one proximity feature has a color appearance that is selected to accentuate and / or complement at least one of the appearances colors of the first dynamic effect feature.
    [0013] According to an advantageous embodiment of the invention, the first dynamic effect feature has a first appearance of color under ambient visible light, a second appearance of color after initial submission to the lighting stimulus and at least a third appearance of color after submitting continuous steady state to the lighting stimulus. In this context, it is of particular interest to use a self-modulating fluorescent component (SMF) as the dynamic effect component, preferably such a component that returns inversely from its modulated color appearance to its contrast color appearance after a certain time. recovery following the cessation of the lighting stimulus.
    [0014] The lighting stimulus preferably consists of electromagnetic radiation incident on the ultraviolet (UV) or infrared (IR) spectrum.
    [0015] According to an embodiment of the invention, the at least one proximity feature has a static color appearance that does not change in response to the lighting stimulus, such a static color appearance is selected to be similar or to accurately correspond to hair. least one of the multiple color appearances of the first dynamic effect feature. Different variants of this modality are revealed.
    [0016] According to another embodiment of the invention, the at least one proximity feature is selected to have a color appearance that is similar to or accurately matches at least one of the multiple color appearances of the first dynamic effect feature. In this context, one, two, three (or even more) proximity features could be provided, each having a color appearance that is similar or accurately corresponds to a different one among the multiple color appearances of the first dynamic effect feature. . Different variants of this modality are revealed, including variants in which the first dynamic effect feature is of the type that has a first appearance of color under ambient visible light, a second appearance of color after initial submission to the lighting stimulus and at least one third color appearance after submitting continuous steady state to the lighting stimulus.
    [0017] According to an additional embodiment of the invention, the first dynamic effect feature has a transient fluorescent color appearance after initial submission to the lighting stimulus and the at least one proximity feature is a static fluorescent feature that includes a component static fluorescent, such a static fluorescent component has an appearance of static fluorescent color after initial submission and continuous steady state to the lighting stimulus. The static fluorescent color appearance of the static fluorescent feature can be particularly selected to be similar to or accurately match the transient fluorescent color appearance of the first dynamic effect feature. Variants of this other modality are revealed including variants that allow the concealment of a predetermined pattern under visible ambient light, such a predetermined pattern only becomes visible after submission to the lighting stimulus.
    [0018] According to yet another embodiment of the invention, the at least one proximity feature is a second dynamic effect feature that includes a dynamic effect component that is also responsive to the lighting stimulus to produce an optical spectral response of dynamic change with the appearance of multiple colors and the optical spectral responses of dynamic change of the first and second features of dynamic effect differ in their color appearances and / or response times. Variants of this additional modality particularly allow the generation of more complex features and patterns that dynamically change in appearance under exposure to the lighting stimulus.
    [0019] In addition, a method is provided to verify the authenticity of the security elements or documents above, comprising the following steps:
    [0020] - submit the document or security element to the lighting stimulus, and
    [0021] - observe the optical spectral response of the document or security element in response to the lighting stimulus.
    [0022] The advantageous modalities of the security elements or documents above form the subject of the dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE MODALITIES OF THE INVENTION
    [0039] The various deployments discussed below are mainly based on the use of at least one dynamic effect feature in combination with one or more proximity features to produce a pattern whose appearance changes dynamically over time in response to incident electromagnetic radiation. a mode that is readily recognizable to lambda users, that is, without requiring complex authentication tools other than a reasonably simple lighting source. In other words, the various modalities discussed hereinafter can be appropriately used as so-called “level two security features” for security documents.
    [0040] A "dynamic effect feature" should be understood as referring to a feature provided on a substrate and including at least one dynamic effect component, such as at least one DEP or SMF pigment, which is responsive to the lighting stimulus of a selected excitation wavelength or wavelength band to produce an optical spectral response, such an optical spectral response changes dynamically over an observable period of time between appearances of multiple colors after and while subjected to the light stimulus .
    [0041] A "proximity feature" should be understood as referring to a feature provided on the substrate and having at least one color appearance and that is located close to or adjacent to the dynamic effect feature. In the context of the present invention, such proximity feature or features have a color appearance that is selected to accentuate and / or complement at least one of the multi-color appearances of the dynamic effect features. Several modalities will be discussed in the following description.
    [0042] Since DEPs are quite innovative, there is still no formalized color theory for how to fully describe their use and effects. For static or traditional pigments, however, (i) the Munsell color system, first published in 1905, provides a model for objectively measuring color. In this model, color is described in three dimensions, hue, value (clarity) and saturation (color purity). Other color systems that provide various means for describing color are known, such as (ii) the CIE triple stimulus color and space model, created by the International Lighting Commission in 1931, which provides three length-dependent color specifications. wave, (iii) the RGB color system, which is based on the additive primary colors red, green and blue and (iv) the HSV and HSL models described by Alvy Ray Smith in 1978, which define colors in terms of (hue, saturation, value) and (hue, saturation, clarity), respectively. All of these systems and others similar to these, however, define color with a set of time-invariant parameters. Pigments, dyes, dyes, pigment and color dispersions, dye solutions and other colored systems and objects are, by association, specified in terms of their static color in some color models.
    [0043] In extreme contrast to traditional pigments and dyes, DEPs have multiple sets of hue, value and saturation that can be used to describe the various appearances of color that they can obtain. These sets of parameters vary over time, usually over a short enough period of time, that an observer can readily detect a change in color parameters. As a precipitate example, a pigment that starts red in ambient white light, then changes to green under some stimulus and then additionally changes to brown under the same stimulus a few seconds later would, by definition, be a DEP. If that pigment changes back to red when the stimulus is suppressed, it can be considered a reversible or recoverable DEP. If the pigment remains in one of these transacted colors when the stimulus is removed, then it can be considered an irreversible or permanent DEP. In the context of the present invention, although reversible DEPs are preferred, irreversible DEPs can also be used and are consequently within the scope of this invention.
    [0044] The following description reveals several implantation modalities and usage paradigms that help to accentuate the appearance of the effect in applications such as when printed on paper with the use of paints and coatings as binders. It must be appreciated again, however, that the following implementations could also be carried out by means of application processes other than printing, for example, incorporation into or over elements that are then applied over or incorporated within a substrate.
    [0045] A preferred modality of a DEP which is contemplated in the context of the present invention and which has already been briefly discussed above is a so-called SMF pigment (Auto-Modulated Fluorescent). An SMF pigment has multiple color appearances as a function of time when viewed in invisible (white) light and subsequently excited with a constant level and intensity of electromagnetic radiation, particularly UV lighting. Such pigments have a first contrast color (C), which can be visualized in ambient light, followed by a second fluorescent color (F), also visible in white light (but triggered by excitation lighting), followed by a third color modulation (M), which is visible in the same white light, the range of colors from which the pigment undergoes a transition within a few seconds, thereby providing a readily observable dynamic appearance. In terms of color specification, this can be presented as SMF [C, F, M], where C, F and M can all have different and independent values of saturation, value and hue as defined by any color model or system by heart.
    [0046] Additionally, these parameters occur or develop in relation to each other as a function of time, with variable time constants associated with the transitions from one appearance to another and can subsequently recover their original color (C) (in the case of pigments Reversible SMF). A Fluorescent Self-modulation pigment with an initial contrast color C, upon illumination with the appropriate electromagnetic stimulus (for example, UV light), will produce fluorescence initially for its fluorescent color F, then move on to the third modulation color M with a time constant T1. The modulation color M will be stable in appearance as long as the electromagnetic stimulus is present at the same level of intensity. When the stimulus is removed, the pigment gradually restores itself back to its original color C with a time constant T2. Thus, an SMF pigment of this nature, considered as a homogeneous material, has at least five parameters associated with it, that is, SMF [C, F, M, T1, T2].
    [0047] In addition to these variables, there is also the initial instantaneous fluorescence brightness and the degree to which the modulation reduces the same, as this reduction does not have to be the absolute zero fluorescence. Figure 1 of this document identifies a “Figure of Merit” (FOM) to describe the relative difference between the fluorescence of an SMF pigment at initial activation (Fi), in relation to the fluorescence in steady state modulation for a lower lever (Fm) ). This relative difference can be called the relative “modulation depth” (MD) of the effect. The relative modulation depth can be specified mathematically using any standard modulation depth equation: MD = (Fi - Fm) / (Fmax - Fmin) [1]
    [0048] where Fmax is the maximum fluorescence that can be obtained by the particle without any modulation and Fmin is the minimum fluorescence that can be obtained by the particle without any modulation. The MD modulation depth could, however, be defined in any suitable way.
    [0049] In other words, an SMF pigment can be represented by at least the following parameters, namely, SMF [C, F, M, T1, T2, MD]. Figure 1 illustrates how an SMF pigment can have different degrees of modulation MD1, MD2, MD3, etc., depending on the formulation of the pigment.
    [0050] SMF pigment systems are described in US Patent Publication No. 2006/0237541 A1 and in International Publication No. WO 2007/005354 A2.
    [0051] Figure 2 schematically illustrates a single particle of reversible SMF pigment under various successive lighting conditions a. a g. The same particle is shown in all occurrences a. a., in ambient (white) visible light (state a.), different successive states with increasing fluorescence modulation (states b. to f.) upon and under continuous and initial steady-state exposure to excitation light (for example , UV light). The state g. illustrates the particle in ambient white light after the particle has returned to its original state. In the states a. and g., the particle exhibits its contrast color C, for example, an ocher color. Upon initial exposure to excitation light (while also still being illuminated with ambient white light), the particle transforms into its initial fluorescent state (shown in state b.) And displays its fluorescent color F, for example, a color fluorescent green. The fluorescence then decreases gradually over time (typically within about two seconds) as schematically illustrated by states c. a e. until it reaches its final modulated state shown in state f. (ie, after the T1 response time) and displays its modulation color M, for example, a dark gray color. Following the removal of the excitation light, the SMF particle returns to its original state g. (that is, after the T2 recovery time).
    [0052] In the illustration of Figure 2, the appearance of the particle in state f. shows the pigment particle in a condition of complete removal, with very little fluorescence still emanating from the particle. In this case, the modulation depth of the activated / deactivated effect, as it passes state b. for state f., it is high. The depth of modulation can be given quantitatively in brightness units such as feet-lamberts or as a percentage of the final brightness of the fluorescent effect, under a constant excitation intensity, in relation to the initial brightness.
    [0053] This particle can recover its initial color appearance C, after the excitation has been removed. The time constant (T2) for this is typically on the order of a few seconds to several tens of seconds or even several years depending on the desired application of the SMF pigment.
    [0054] In the illustrative example above, the designation for the SMF pigment can be SMF [ocher, green, gray, 2, 20, 80], where ocher is the contrast color C, green is the fluorescent color F, gray is the modulation color M, 2 and 20 are the removal of modulation and recovery time constants T1, T2 in seconds and 80 is the percentage of the initial fluorescence that is eliminated by the modulation effect of the pigment.
    [0055] Figure 3 schematically illustrates the effect of an SMF pigment (similar to the SMF pigment discussed in reference to Figure 2) that has been integrated into a binder and applied to a substrate. The region in which the pigment / binder was applied to the substrate has the first appearance of the contrast color C (for example, ocher) when viewed in ambient white light (state a.). When excited with the appropriate stimulus (for example, UV light), the stimulated region instantly fluoresces green (state b.), Then removes the fluorescence (states c. A and.) By modulation and changes to gray (state f. .) in about two seconds. The stimulated region recovers the initial contrast color (g. State) in about twenty seconds when the stimulus is removed.
    [0056] Figure 4 shows a series of photographs of a raw SMF pigment in a plastic bag. The SMF pigment can be seen in its initial form (state a.), Through instant fluorescence initiated by a small UV lamp (state b.), Then, as the fluorescence is gradually removed by modulation under the same light intensity (states c. and d.). Modulation typically takes about two to three seconds to reach its steady state value. When UV excitation is suppressed, the gray modulation color typically remains for about twenty to thirty seconds, illustrating that the recovery time constant is not instantaneous.
    [0057] Figure 5 shows the same effect as described in Figure 4, but on a pigment that has been integrated into a binder and applied to a substrate. The printed effect of the pigment is substantially the same as that described in the form of raw pigment.
    [0058] DEPs, such as the SMF pigments described above, can be printed, applied or integrated on a variety of substrates including, but not limited to, paper or plastic substrates. Its effects can be readily visualized and observed under the necessary lighting conditions. Its effects can be accentuated through judicious usage paradigms and the creative selection of colors and resources in its proximity as it will be necessary from now on. Proximity colors and proximity features are those that are close enough to the dynamic effect component that the pigment effect can be seen in relation to them, allowing for a dynamic comparison to be made as the DEP feature passes through its phases and / or colors. In this regard, according to the invention, the region in which the selected dynamic effect component is applied can be located adjacent to the proximity colors / features (see Figures 6a to 6c, 8a to 8d, 9a, 9b, 10, 11) or in close proximity (see Figures 12 to 15).
    [0059] In addition to the use of proximity colors / resources, the research methodology can also be used to accentuate and explore certain attributes of DEPs. Such research methodology assumes that the area being subjected to the lighting stimulus at a given point in time is larger than the area where the dynamic effect component is applied and located (as, for example, illustrated in Figures 6a to 6c). In other words, the dynamic effect feature (region 100 in Figures 6a to 6c) is less in the surface area (area A in Figure 6a) than the area (area B in Figure 6a) being illuminated at a given point in time. In this case, the proximity color (s) / resource (s) is (are) formed by the regions (such as regions 101 and 102 in Figures 6a to 6c) located close to or adjacent to the region in which they are located. the dynamic effect component is applied.
    [0060] Such a research methodology could, in particular, make use of a large area light source adapted to illuminate the entire area of interest, such a large area light source is typically already in use in the art for investigating banknotes and documents similar security measures. A benefit of this research methodology is that it can be seen in its entire perimeter in relation to other colors of proximity and undergoes a uniform change even if the source of excitation is vibrated by a small amplitude. Such vibration from the source of effective excitation may result from light hand movements if either the illuminator or the substrate is portable.
    [0061] Another research methodology assumes that the area being subjected to the lighting stimulus at a given point in time is smaller than the area where the dynamic effect component is applied and located (as, for example, illustrated in Figures 7a to 7c). In other words, the dynamic effect feature (region 110 in Figures 7a to 7c) is greater in the surface area (area A in Figure 7a) than the area (area B in Figure 7a) being illuminated at a given point in time. In the latter case, the proximity color (s) / resource (s) is (are) formed by the adjacent regions in which the dynamic effect component is applied and which are not being excited.
    [0062] This other research methodology could, in particular, make use of small light sources, such as LED (Light Emitting Diode) devices as to the occurrence shown in Figures 4 and 5, which are only adapted to illuminate a localized area. In contrast to the previous research methodology, the small localized vibration or movement of the light source in relation to the feature to which the dynamic effect component is applied can be used to continuously induce fluorescence around the edges of the region where fluorescence has already occurred. it was modulated to the steady state removal condition and the color was changed to the modulation color M (as schematically illustrated in Figures 7b and 7c). As long as the light source is incident on any portion of the resource 110 for only a short period of time (t << T1), only the fluorescence will be removed from the resource through the stimulus, as the modulation will not have enough time to modulate the fluorescence down to the steady state level. Thus, the vibration of the excitation source can be effectively employed to create a dynamic proximity feature using the fluorescent color F, which is different or the contrast color C or the modulation color M, after the steady state modulation of the effect has occurred.
    [0063] Figures 6a to 6c and 7a to 7c illustrate the small and large dynamic effect features in relation to the light source and highlight how research methodologies can be used to further accentuate the dynamic effect of any particular DEP feature, such as as an SMF resource.
    [0064] Turning to Figures 8a to 8d, several modalities are shown that are all based on the provision of a dynamic effect feature on the substrate to which a dynamic effect component is applied, such a dynamic effect feature is close or adjacent (in this case immediately adjacent) to the first and second proximity features provided on the substrate, these proximity features have respective color appearances that are similar to or accurately match at least one of the multi-color appearances of the dynamic effect feature. More precisely, all the modalities shown in Figure 8a to 8d comprise the three features that form concentric circles, the central and outer regions that form the proximity features and that have static color appearances, while the middle circle region forms the feature. of dynamic effect and comprises at least one component of dynamic effect, in order to exhibit an optical spectral response of dynamic change in response to a lighting stimulus. In these preferred examples, the dynamic effect feature comprises at least one self-modulating fluorescent component that exhibits an appearance of contrast C color under ambient visible white light (state a. In Figures 8a to 8d), an appearance of fluorescent color F after submission initial to the lighting stimulus (state b. in Figures 8a to 8d) and a color-modulated appearance M after the submission of continuous steady state to the lighting stimulus (state c. in Figures 8a to 8d).
    [0065] As shown in Figures 8a to 8d, various effects can be created by manipulating the color appearances of the proximity features adjacent (or close as may be the case) to the dynamic effect feature.
    [0066] In the illustration in Figure 8a, the proximity color of the central region 120a is selected to be similar to or correspond to the contrast color C of the dynamic effect feature in region 120, while the proximity color of the outer region 120b is selected to be similar to or match the fluorescent color F of the dynamic effect feature in region 120.
    [0067] In the illustration in Figure 8b, the proximity colors of both the central and outer regions 121a and 121b are selected to be similar to or correspond to the M modulation color of the dynamic effect feature in region 121.
    [0068] In the illustration in Figure 8c, the proximity color of the central region 122a is selected to be similar to or correspond to the fluorescent color F of the dynamic effect feature in the region 122, while the proximity color of the external region 122b is selected for be similar to or match the M modulation color of the dynamic effect feature in region 122.
    [0069] In the illustration in Figure 8d, the proximity color of the central region 123a is selected to be similar to or correspond to the contrast color C of the dynamic effect feature in region 123, while the proximity color of the external region 123b is selected. to be similar to or match the M modulation color of the dynamic effect feature in region 123.
    [0070] A variety of dynamic effects can thus be produced by manipulating the color appearances of the proximity features to match any of the color appearances of the dynamic effect feature.
    [0071] By manipulating the dynamic color tones of the dynamic effect feature and the proximity colors of the proximity features, it is also possible to substantially hide the dynamic effect feature under visible ambient light, prior to submission to the lighting stimulus (such as , for example, shown in Figure 8a or 8d). This may be desirable to do for some applications where the dynamic effect feature is intended to be obscured or hidden under normal lighting conditions for security and / or artistic purposes.
    [0072] Similarly, choosing a proximity color that corresponds, for example, to the dark tone color appearance of the dynamic effect feature in its removed state by modulation will lead to a reduced contrast between the dynamic effect feature and the (s ) proximity color (s) (as, for example, shown in Figures 8b, 8c and 8d), giving the impression of a relatively short flash of fluorescence after submitting the resource to the lighting stimulus.
    [0073] Other combinations are obviously possible, and it is particularly understood that, in the case of an SMF resource, the color appearance of the resource gradually changes from fluorescent color F to modulation color M, meaning that any of the proximity colors could be selected to match any of the transition states between fluorescent color F and modulation color M of the SMF feature.
    [0074] The dynamic effect feature, defined as the region in which the DEP pigment (for example, SMF) was printed or otherwise applied to the substrate, can take various forms regardless of whether the proximity features are light-colored, dark or medium. This feature may be small so that the light source completely covers it when the feature is illuminated (as already discussed in relation to Figures 6a to 6c of this document) or it may be larger than the area excited by the light source in a determined point in time so that the dynamic effect occurs somewhere within the dynamic effect feature (as already discussed in relation to Figures 7a to 7c of the present document). In both cases, the pigment transition can be accentuated in relation to one or more colors of proximity that do not change under stimulating conditions.
    [0075] A particularly effective use paradigm that involves proximity colors includes the respective proximity colors in which each corresponds to a corresponding one among the transition colors of the dynamic effect component. In the particular case of an SMF resource with the transition colors C, F, M as discussed above, such proximity colors could particularly include a proximity color that accurately matches the contrast color C of the SMF resource, a proximity color that corresponds accurately to the fluorescent color F of the SMF resource and / or a proximity color that accurately corresponds to the modulation color M of the SMF resource, any combination being possible.
    [0076] In such a case, the dynamic effect feature starts from one color and then appears to grow to match another color, momentarily, while the effect is in progress. This apparent growth of the feature to fill the combined dynamic effect / proximity feature union is very effective when the dynamic effect feature is smaller than the area that is stimulated by the light source, so that the entire dynamic effect feature assume at least one of the transition colors of the dynamic effect component.
    [0077] A possible example is shown in Figure 9a in which the dynamic effect feature (here comprising an SMF pigment) is applied to a region 130 (taking the shape of a disc in the illustration) adjacent to three proximity features 131, 132 , 133 (here taking the form of strips) each having a color of static proximity that corresponds to a respective one of the contrast color C, the fluorescent color F and the modulation color M of the SMF resource. Under ambient white light (state a. In Figure 9a), the color appearance of the SMF feature corresponds to that of lines 131 and, after submission to the lighting stimulus, changes initially to its fluorescent color appearance to match the color appearance of the lines 132 (state b. in Figure 9a) and then gradually changes as fluorescence is being modulated to match the color appearance of lines 133 (state c. in Figure 9a). This modality will produce an impression of similar movement, under exposure to the lighting stimulus, between the second and third proximity features 132, 133, as in the case illustrated in Figures 6a to 6c.
    [0078] In a special case, the M modulation color of the SMF feature can be chosen to match or be similar to the contrast color C. In such a mode, the dynamic effect feature will change from the contrast color C to the fluorescent color F , then back to the contrast color again as the fluorescence is modulated. When the modulation color accurately matches the contrast color, the feature will appear to pass through a momentary fluorescent pulse under continuous stimulus with incident electromagnetic excitation.
    [0079] This special case is illustrated in Figure 9b, in which the dynamic effect feature is applied to a region 135 (again taking the shape of a disc) adjacent to the proximity features 136, 137 (again taking the shape of strips) each having a color of static proximity that corresponds to a respective one between the contrast color C and the fluorescent color F.
    [0080] Another modality includes integrating a dynamic effect component, having a transient fluorescent response, next to a proximity feature that produces fluorescence under the same lighting stimulus that induces the dynamic effect in the dynamic effect feature, however, with a response static fluorescent. Here, the fluorescent color of the proximity feature can be the same as the transient fluorescent color of the dynamic effect feature (but not necessarily). SMF components are again of particular interest in this context. Thanks to such a combination, the portion of the resource that is provided with the non-modulating fluorescent component will glow for the duration of the lighting stimulus, at a constant emission level. In contrast, the SMF feature will shine initially, but then be removed by modulation, providing a distinction between the static fluorescent region and the self-modulating fluorescent region. When the excitation source is suppressed, the static fluorescent region will stop glowing, but the modulated region will retain part of its color modulated for the T2 recovery time constant.
    [0081] Figure 10 illustrates this effect with a feature that forms a predetermined pattern P1, namely an "X". In this example, a portion of the “X” (designated as region 141 in Figure 10) exhibits a static color appearance that is preferably selected to match the M modulation color of the SMF feature, another complementary portion of the “X” (designated as region 140 in Figure 10) that comprises the SMF component. In this example, the contrast color C of the SMF feature is advantageously selected to be white or very light tint, in order to substantially hide the SMF feature under visible ambient light. For the sake of illustration, the SMF component could have the following parameters: SMF [white, green, gray, T1, T2, 90]. In addition, an additional region 142 is formed close to regions 140, 141, such additional region 142 comprises a static fluorescent component that exhibits an F * fluorescent color after being subjected to the lighting stimulus. In the illustration of Figure 10, this additional region 142 advantageously forms a contour around at least part of the regions 140, 141.
    [0082] As shown in Figure 10, the resulting pattern will first appear as a single line or bar formed by the proximity color of region 141 (state a. In Figure 10) will then change to a pattern (state b. In Figure 10) in that regions 140 and 142 become fluorescent with their respective fluorescent colors F and F * (which may correspond to each other) and will gradually change to a pattern (state c. in Figure 10) in which region 140 is being removed by modulation while 142 regions remain fluorescent. Upon suppression of excitation (state d. In Figure 10), region 142 stops producing fluorescence, while region 140 initially retains its residual modulation color M. As time goes by, region 140 reversibly returns to its original state so that only region 141 remains visible (state e. in Figure 10).
    [0083] In addition to being properly integrated with proximity features and static colors, DEPs can be applied with multiple proximity colors over a wide range of resources. In particular, resources can be produced in the form of line segments with alternating regions that comprise a dynamic effect component and regions that comprise only static color components, so that the portions of the line segments exhibit an optical spectral response of dynamic change , in contrast to the static response of the remaining portions of the line segments.
    [0084] This principle is put to use in the modality illustrated in Figure 11. This Figure shows a feature formed with the use of alternating line segments 15, 16, in which some line segments 15 are made up of regions 150 that comprise at least a dynamic effect component that has a transient fluorescent response interspersed with regions 151 that have only a static color component and in which some line segments 16 include regions 160 that comprise a static fluorescent component that has a static fluorescent component.
    [0085] In this particular example, the line segments 15, 16 are interspersed and the respective resources 150, 160 are arranged in such a way as to form a predetermined pattern P2 (in this case, the number "20"). In addition, the dynamic effect component is selected in this example to be an SMF component whose contrast color C is chosen to accurately match the color of proximity of the static inactive portions 151 of the line segments 15, thus hiding the dynamic active regions 150 under light. white environment. static fluorescent component is selected to be substantially white or very light in its inactive state, such as to substantially hide active regions 160 under ambient white light. In such a case, the overall appearance of the feature under visible ambient light (state a. In Figure 11) does not immediately reveal the presence of any particular pattern in the design itself.
    [0086] After the initial submission to the incident electromagnetic radiation (state b. In Figure 11), the predetermined pattern P2 is instantly revealed by regions 150 and 160 that begin to produce fluorescence in their respective fluorescent colors F and F * (which could be the same or different). Under continued steady state exposure to the light stimulus (state c. In Figure 11), the regions 150 that form the predetermined pattern P2 are removed by modulation to become their M modulation color, while regions 160 continue to glow, producing an easily recognizable general change in the appearance of the P2 standard. Upon removal of the excitation (state d. In Figure 11), regions 160 stop producing fluorescence, leaving only a partial residual representation of the predetermined pattern P2 formed by regions 150 that initially maintains its M modulation color before returning to the contrast color initial C after the relevant recovery time T2.
    [0087] Figure 12 illustrates another modality of a safety feature in accordance with the invention in which the first and the second dynamic effect features 171, 172 are applied in corresponding (or adjacent) corresponding regions and in which the optical spectral responses of dynamic change of the first and second dynamic effect features differ so that the resulting appearance of the pattern formed by the dynamic effect features produces the impression of a color shift under exposure to the lighting stimulus. In this particular example, the dynamic effect features 171, 172 together form a predetermined pattern P3, taking the shape of a flower in this illustration, where the first dynamic effect feature 171 changes from its C1 contrast color under visible ambient light to a modulated color M1 after exposure to the light stimulus, where the modulated color M1 is selected to be similar or accurately to the contrast color C2 of the second dynamic effect feature 172. Similarly, the second dynamic effect feature 172 changes its contrast color C2 under ambient visible light to a modulated color M2 after exposure to the light stimulus, where the modulated color M2 is selected to be similar or accurately to the contrast color C1 of the first dynamic effect feature 171.
    [0088] SMF pigments could be used in the context of this modality, therefore, it is understood that one can also use DEPs that do not have a momentary fluorescent appearance after initial submission to the lighting stimulus.
    [0089] Figure 13 illustrates an additional modality of a safety feature in accordance with the invention in which three features of dynamic effect 181, 182, 183 that have different response times are applied in corresponding close or adjacent regions of the substrate so that the appearance resulting from the pattern formed by the dynamic effect features produces the impression of a gradual change under exposure to the lighting stimulus. The P4 pattern formed by the dynamic effect features 181, 182, 183 here consists of single bar elements that accentuate the dynamic shifting effects of the various dynamic effect components.
    [0090] Other patterns are obviously possible, as, for example, illustrated in Figure 14 in which a P5 pattern that takes the shape of a flower consisting of the first and second dynamic effect features 191, 192 with different response times ( and possibly color appearances) is shown.
    [0091] Figure 15 illustrates yet another modality of a security feature in accordance with the invention in which the first and second dynamic effect features 200, 205 are applied in corresponding regions close to the first and second proximity features201, 206 in which each has a static color appearance, in which the appearance resulting from the P6 pattern formed by the dynamic effect features200, 205 and the proximity features201, 206 produces the impression of a change in spatial frequency under exposure to the lighting stimulus.
    [0092] For this purpose, the first dynamic effect feature 200 is selected to have a C1 contrast color (for example, a red color) and an M1 modulation color (for example, a blue color) that accurately matches the appearance static color (for example, red) of the second proximity feature 206 and the static color appearance (for example, blue) of the first proximity feature 201, respectively. Conversely, the second dynamic effect feature 205 is selected to have a C2 contrast color (for example, a blue color) and an M2 modulation color (for example, a red color) that accurately matches the appearance of a static color the first proximity feature 201 and the static color appearance of the second proximity feature 206, respectively.
    [0093] In the first state (state a. In Figure 15), that is, under ambient visible light, the P6 pattern exhibits alternating red and blue bars with a certain spatial frequency. In the second state (state b. In Figure 15), after exposure to the lighting stimulus, the first and second dynamic effect features 200 and 205 become their respective modulation colors M1, M2, thus changing, in appearance, the spatial frequency of the bars that form the P6 pattern.
    [0094] Various modifications and / or improvements can be made to the modalities described above without departing from the scope of the invention as defined by the attached claims. For example, although reference has been made to SMF pigment components, other types of DEPs can be put in place to achieve similar effects.
    [0095] Additionally, combinations of the modalities described above are possible. For example, in the modalities of Figures 8a to 8d, it is possible to contemplate the application of a static fluorescent component in any of the proximity features that surround the dynamic effect feature, in which the static fluorescent component could exhibit a fluorescent color appearance. similar or accurately corresponding to the fluorescent color appearance of the dynamic effect feature.
