TW200922808A - Provision of frames or borders around pigment flakes for covert security applications - Google Patents

Abstract

Opaque flakes, such as pigment or bright flakes used in paints and inks, have a selected shape and/or other indicia to provide a covert security feature to an object. Shaped opaque covert flakes are not readily detectable by causal observation, but in some embodiments are easily seen at 50X magnification. In manufacturing the flakes a sheet of embossed frames are provided having embossed symbols or indicia within. Upon removing a coating from the embossed sheet the coating material tends to break along frame lines or grooves and the resulting flakes are substantially uniform in size. In order to have the flakes break along frame lines or grooves more readily than along the embossing or grooves defining indicia within a frame, the frames are provided with a deeper groove than indicia grooves. As well a groove having a different shaped profile conducive to breakage can be used for the frame grooves whereas a groove having a profile less conducive to breakage can be used to form the indicia grooves. We have found that the flakes can be further protected from breakage by coating them in a protective coating. This coating may have other features which makes the logo more visible.

200922808 IX. INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates generally to thin-faces and, more particularly, to providing boundaries around marked towns and slabs used in coating compositions. Or the border and the border area of the sheet are provided by the 丨/, 田 or a plurality of grooves in the field; and more specifically, the present invention is in the form of a grooved sign In contrast, the standard grooved frame is less stable and more [Prior Art] Specially used pigments have been developed for use in anti-counterfeiting patterns such as printed on Saki, high-value items, and container seals. And its 5 acres are used for commercial items. For example, the U.S. twenty-dollar Federal Reserve Note §., s oie) witnessed the use of photo-changeable inks. The color printed on the lower right corner of the front of the banknote changes with the change of the persuasion. This is the appearance of the outside of the Pakistani 1 reading corner q | brothers Wanma pattern. The color change is overwritten by a conventional color photocopier and receives a paper security feature to determine the authenticity of the tape. Whether it has a change:: High-value documents and targets use similar measures. For example, iridescent pigments or diffractive Yankees are used in paints such as stocks, passports, original products, or in paints used in seals (which are used in articles). Due to the technology of the counterfeiter, the second security feature. ^ The anti-counterfeiting method that is difficult to forge is based on the multi-layered change. ★Hai et al. And the temple pays for hunting by a local variation such as the reflectivity of the sheep, which is formed on at least one of the layers of the 126980.doc 200922808 dichromatic pigment flake. The multilayer color-changing pigment flakes generally include a Fabry Perot-type structure, and the ns a r- has a layer. The absorption layer separated by the reflective layer. The reflective layer pass f is a metal layer, and the pigment flakes are substantially opaque. If most of these types of pigmented flakes and other pigments are mixed, the resulting color can be significantly different from the pigment.

When these sheets are mixed with other pigments, they are difficult to find. I Another technique uses a poly-peptidic diacetate, which is formed by epoxy resin encapsulation, and a) sheet. A reflective layer is deposited on a roll of ρΕτ and the PET is cut into small pieces. The sheets are coated or encapsulated with a ring-turn resin to improve the durability of the reflective layer. Such flakes may be obtained in various shapes such as square, (four)...triangle and ', single quotation marks (apQstr〇phe), and optionally: #银锡釓合金, gold and copper reflective metallic color. However, the ring (10) lipid layer and the relatively thick PET substrate (which is used in the vacuum deposition process, typically having a thickness of about 13 microns (0.5 mils)) produces relatively thick flakes that pass through U microns. Unfortunately, if the thickness is much larger than the matrix pigment, then such a thick sheet applies a sigma to the concealment. Similarly, when the thick sheet = the flow in the ink is not good and the knot is thick in the paint: a thick sheet of the surface is usually applied: a thick transparent outer coating. Need to be able to overcome the above-mentioned swearing-recognition & mark target. The invention relates to a concealed anti-counterfeiting pattern. The present invention relates to a sheet which has a mark or concealed symbol which is mechanically embossed or pressed by a mechanical means: or by laser, /, these hidden symbols are visible under the microscope. In order to preserve the completion of these symbols, when all or part of the hidden symbols are provided around the individual support of the deposited support structure, most of the provided border lines are broken, instead of In the absence of control (in which the fault line is additionally broken with a larger break (5), *, 4 money, etc.), try to ensure that the production edge is cracked, and the border groove can be wired or The groove is broken, and the groove of the hidden symbol of the concealed symbol has a different profile, which causes the groove of the frame to be fined or broken. In a case/covering, the groove is more susceptible to breakage =::: Ben! In the preferred embodiment, the thin or the eve is four or more or less than the one or more symbols. On the side of the eyebrows, there is a grooved border with a border to make the sheet = uniform square or rectangular break. Of course, it can also be borrowed in this way: in addition to the three sides before the sheet By adding a border symbol, the m (four) piece provides a conventional release layer to remove the substrate or support layer, and causes the sheets to break when removed. Using a laser, a residual or The film is imprinted on the substrate, and the bezel can be made in a similar manner to the symbol; in a preferred embodiment, the bezel is provided in the same manner along with the formation of the symbol. The term "flower sheet" as used hereinafter is described by Applying pressure to the sheet by an embossing tool or applying a force to the sheet in the form of a substrate on the thin flower substrate by being applied to the embossed substrate. Accordingly, it is an object of the present invention to provide a sheet having symbols thereon, and wherein the symbols have or have been embossed, embossed or laser-to-sheet or a frame of a sheet molded from an embossed temporary support.

[Implementation] I. Introduction Used to conceal safety applications _; μ Application (4) Sheet 4 is often not visible by general observation. Some types of inspection techniques such as examination under the microscope or analytical techniques such as elemental analysis are used. In one embodiment, the opaque sheet containing the label, such as a particular shape, is substantially matched to the visual characteristics of the bulk pigment or other material to which it is blended. In a particular embodiment, a single layer of inorganic opaque sheet having a selected shape is mixed with an iridescent mica based sheet or other matrix pigment. For the purposes of this discussion, a "single layer" of inorganic material includes multiple layers of the same inorganic material superposed on each other. In particular, inorganic concealed sheets are required for applications in which heat, solvents, sunlight, or other factors can degrade organic sheets. Inorganic concealed sheets for use in explosives are detectable and resistant to environmental exposure even after exposure to elevated temperatures and/or pressures. Sheets in accordance with embodiments of the present invention are also substantially thinner than conventionally formed sheets, Typically less than about 1 micron, such that it can be used in inks and it produces a smooth surface finish in the paint without the need to use a clear outer coating. Thin, inorganic flakes according to embodiments of the invention also have Closer to the density of matrix pigment flake density made using similar techniques. Thick flakes incorporated into organic substrates typically have a different density than thin tantalum matrix pigment flakes and can be split before or during application when the carrier is a fluid. Separation can lead to concealment and the ratio of matrix flakes in the composition is inconsistent, so the flake system is undesired, and if the split causes improper The concealed sheet of concentration 126980.doc •12-200922808 can then degrade the concealing properties of the concealed sheet. II. Exemplary opaque sheet Figure 1 is a portion of a document having a security feature i 2 in accordance with an embodiment of the present invention. Plan view. At least a portion 14 of the security feature 12 is printed with an ink or paint comprising an opaque sheet having a logo (hereinafter referred to as "concealed sheet"), which are mixed with a bulk pigment such as a bulk pigment sheet. In an embodiment, the concealed sheets have a specific shape, such as

The shape is square, rectangular, trapezoidal, "diamond" or circular. In another embodiment, the concealed sheets comprise a grid pattern with or without a selected shape. The selected shape is preferably by embossing, Etching or using a laser to create a bezel or border, the lamella will break along the rim or boundary as it is removed from its temporary support substrate. In a particular embodiment, the grating pattern has a non-spectral visible range Optically active grid spacing. That is, such grid patterns do not form visible diffraction gratings. Although not all marking sheets are necessarily concealed sheets, sometimes concealed sheets are also referred to as marking sheets. 'The bulk pigment particles comprising the bulk pigment flakes have an irregular shape. In an embodiment the concealed flakes may be distinguished from the bulk pigment flakes by their shape. Alternatively, the bulk pigment flakes have a first selected shape and the concealed flakes have a second The shape is selected. The fabrication of the shaped pigment flakes is accomplished by various techniques, such as using a patterned substrate to: deposit the sheet material on the substrate, and then The substrate is separated from the sheet to obtain a pattern such as a border or a border; or the patterned sheet is cut from the thin sheet material using laser or other means. The selected shape of the concealed sheet can be, for example, manufactured; Or other aspects of (4) or (4) document 126980.doc 13 200922808 Ink associated. A waste coater is a type of device that can be used to make a concealed sheet that is selectively shaped or randomly shaped in accordance with embodiments of the present invention. The tantalum layer (also referred to as "web") of the polymeric substrate material is applied through one or more deposition zones and through one or one of the phase layers. The roll of the polymer substrate can be passed back and forth through the 〆 固 固 尤 尤 尤The (equal) film layer is then separated from the polymer substrate and processed into a sheet. Other devices and techniques can also be used.

♦ The hoisting is required to limit the total thickness of the thin M layer deposited (and thus removed) from a roll of polymeric film substrate to less than about a meter. PET is a type of polymer film substrate for a roll coater, and the PET film substrate is usually at least about = m thick. Thinner PET films tend to be thermally deformed during the vacuum deposition process. When the polymer substrate passes through the deposition zone, the heat of the deposition zone and the heat of condensation of the deposited one or more film layers both increase the temperature of the polymer substrate. So, from the yang membrane cutting and merging? The minimum thickness of the sheet of _ is (four) microns. In addition, the sheet having the selected shape is preferably embossed to the base cage by the frame "to achieve" 4 sheets and the like will be separated and broken along the frame, and the hidden slab is preferably inside the frame and bordered by the frame. The boundary includes one or more symbols, other forms of marks, and/or a grid pattern. .u killing the grid to the roll for deposition before depositing or otherwise forming a film layer that is processed into a tile On another substrate, in a different embodiment, when the cage layer is peeled off from the deposition substrate and processed into a sheet, the selected amount (the surface area of the substrate is embossed in a grid pattern or a pattern of shapes) To obtain the concealer of the selected 盥A 皙 μ μ 目. 4. This technique provides a blunt smear of (4 film composition and thickness). For example, the lattice is adjusted to η, ; ^ Pattern and / or shape pattern embossing] 0% of 126980.doc -14· 200922808: product = area will produce a pigment mixture with about · concealed sheets, not showing the shape / symbol of the sheet and unformed / flat thin Blends of different optical designs. Different types of shots can be taken in the same vacuum process. Design, "This is not preferred. Preferably, the substrate is produced with a different surface area than the dust surface, and the substrate is deposited to obtain a mixture of different (four)' or different patterns to obtain different shapes and / Or a grid pattern. It is a simplified diagram of a deposition substrate η having a I flower portion 13 and an unmated portion 15. The _ portion has a frame, which is exaggerated for illustrative purposes and additionally or optionally (for example) a grid or symbol, and the unembossed portion is substantially smooth. Alternatively, the untwisted portion has a different border, grid or symbol. A flower portion 13 and a surface area without the flower portion 2 The ratio produces a selected amount of marking sheet (produced from the embossed portion) having the same film structure as the substrate sheet (produced from the unaltered portion)" although the deposition substrate U is shown in the roll deposition machine (4)) : Ding into 3 4 19 ' But alternative embodiments use different types of substrates and deposition systems. Fig. 2B is a simplified view of a portion of the deposition substrate 11 having the embossed portion 13 and the unembossed portion ". Even if the pigmented sheet with the identifiable mark is easy to observe, it also provides the Angkor's special, while the pigmented sheet with the identifiable mark on the right is difficult to observe, and the counterfeiter does not even notice the existence of the hidden sheet. One embodiment of the present invention uses a concealed relief sheet having optical characteristics with the matrix pigment (4). Concealed pigment flakes are not visible from unassisted human vision, but are visible at approximately 5〇X to 1〇〇〇X. A concealed pigment having substantially the same visual characteristics 126980.doc -15- 200922808 The flakes can be mixed with the matrix pigment in a wide range of proportions without significantly affecting the color of the composition. In some embodiments, the concealed pigment flakes are readily identifiable in a composition having 5 to 1% by weight of the concealed pigment flakes and having 95 to 90% by weight of a matrix pigment flake having a similar appearance (eg, color and/or color). Often 'formed opaque concealed sheets are readily identifiable in the field of view using hand-held microscopes (e.g., "shirt-pocket" microscopes) and require less magnification for identifying sheets of similar size with symbols. f

Another method is to use an opaque concealed sheet of a selected shape that is different in color from the substrate sheet. In one embodiment, the opaque concealed sheet is a bright metallic silver ("silver") sheet having a thin film of aluminum or other reflective material between layers of dielectric material such as MgF2. The bright flakes typically have a high range over a wide range of visible wavelengths. Reflective, and generally does not have a characteristic color. The ruthenium sheet made of gold or copper may exhibit, for example, a yellowish or reddish color. It has been found that it may be added in the chromogenic matrix pigment from about 〇25.5% by weight to about 5 wt% shaped (e.g., diamond shaped) party flakes do not cause noticeable color changes, but are still easily identifiable under about 50X illumination magnification (i.e., 5 fold magnification). The shape of the sheet is magnified by illumination. And high brightness distinguishes it from the matrix flakes. When less than about 0.25% of the formed brilliant flakes are used, the concealed flakes become difficult to measure: because the dilution of the matrix flakes results in less bright and thin light in the field of view. When the amount of flakes exceeds about 5% by weight, the color (eg, hue) of certain types of flakes (especially dark flakes) changes. In these examples, too many flakes are substantially "diluted" of the matrix pigment. $ Beggar's color. However, 'the use of shaped bright flakes in the composition with discoloration is a good idea, because you add a small amount of single 126980.doc -16 - 200922808 one type of shaped bright flakes to many Different types (color and/or color) of pigment flakes, and a relatively small number of formed flakes provide a hidden security feature. Similarly, compositions containing pigments and flakes are not used for replacement or otherwise contain 100% In applications where the composition of the pigment flakes differs, color dilution is not critical. Pigments are typically mixed in a carrier to form a paint or ink. Examples of carriers include polyethylene glycol, polyvinyl acetate, polyvinyl ketone , poly(ethoxyethylene), poly(methoxyethylene), poly(propylene) acid, poly(acrylamide), poly(ethylene oxide), poly(maleic anhydride), hydroxyethyl cellulose , cellulose acetate, poly (sugar) such as gum arabic and pectin, poly (acetal) such as polyvinyl butyral, poly (ethylene halide) such as polyvinyl chloride and polyethylene chloride, such as poly Poly(diene) of a diene, poly(olefin) such as polyethylene, poly(acrylate) such as polymethyl acrylate, poly(methacrylate) such as polymethyl methacrylate, such as poly(oxygen) a poly(carbonate) of a carbonyloxy group, a poly(ester) such as polyethylene terephthalate, a poly(urethane), a poly(oxane), a poly(sulfur) Poly(sulfone), poly(vinyl nitrile), poly(acrylonitrile), poly(styrene), poly(2,5-dihydroxy-indene, 4·phenylene vinyl) poly(phenylene) , poly(decylamine), natural rubber, furfural, and other polymers and polymers and mixtures of polymers and solvents. Figure 3A is a simplified plan view of a portion 14A of one of the security features 14 shown in Figure 1. Seeing the shape of the sheets, the portion 14 A of the security feature is observed at a magnification of typically about 2 〇χ 30 '. 'The cross is usually about 5 〇〇 micro plucking', more usually about 20 psi. 40 microns. This safety feature uses 126980.doc •17· 200922808 concealed pigment thin film j4 I 8 >, rk Μ ί 十溥 including matrix pigment particles 16 and having a selected shape (in this case a "diamond shape)) Ink printing of the sheet 18. The concealing pigment 庳::: is chosen such that the composition prepared from the matrix pigment particles is not disturbed: the matrix pigment particles 16 are illustrated as irregularly shaped sheets. Or the 'matrix pigment flakes have a selected (i.e., regular) shape. Similarly, the hidden: pigment flakes 18 can have a grid. Adding a grid further increases the difficulty of counterfeiting. = In the case of the actual case, the concealed pigment flakes 18 generally have the same optical characteristics as the matrix particles. Alternatively, the concealed pigment flakes (4) have optical characteristics different from those of the base gravitational particles, but are in an amount sufficiently small that they do not disturb the visual appearance of the compositions made with the matrix pigment particles. In a particular embodiment, the "diamond" concealed sheet cross-section Css) is a bright sheet of about 25 microns by 35 microns. The shaped sheets are embossed into a roll of PET deposited substrate material by a diamond pattern, and then a bright sheet is deposited (eg, between about 〇〇 约 各 约 约 约 约 约 约 约 约 约 约 约 约 约 约 约 约 约 约 约 约 约 约 约 约 约The standard film design of nmA1) is made. The total thickness of the bright flakes is about 9 〇〇 nm' which is about i microns. The embossed pattern is also referred to as "the border is opposite the grid, which is used to create a pattern in or on the sheet, and in some embodiments is positive and negative in other embodiments (negtive ). In addition to the diamond sheet itself providing some measure of concealment characteristics when it is in some predetermined ratio distribution with other irregularly shaped sheets, the diamond sheets may additionally conceal the symbol embossing ' thereby providing two levels of available Concealed features to protect the pattern. The combination of the metal layer and one or more dielectric layers facilitates removal of the wafer from the deposition substrate. Only thin film stacks with dielectric layers are fragile and typically have residual stresses from the deposition 126980.doc 200922808. These thin film stacks are more prone to follow =: flakes. All metal stacking or single layer is difficult to deposit according to the substrate:: Frame processing into patterned sheet 1 is relatively easy to extend metal.

In the example, the total thickness is between about 〇5 μm and about 3 μm. H = metal-dielectric flakes provide good ductility and fragile characteristics =: electricity: results in "good removal of the substrate when the substrate is removed and cured" In a special example, having a total thickness between the fragile dielectric layers of about one

The formed bright flakes of the genus layer are produced from the embossed deposition substrate. The film layers are peeled off from the deposition substrate and processed into a sheet using conventional techniques. The embossed diamond pattern provides a line along which the film layer is broken into sheets having a selected diamond shape. In another implementation, the diamond flakes are about 12 microns by 16 microns' and include grids on the major surfaces of the sheets. The grid is nominally 2 lines per mm and # does not produce significant diffraction in the composition when used as a marker. The shape of the 12x16 micron sheet is easy to see at 100X magnification; however, the grid is not visible at this magnification. The grid is easily visible at 400X magnification. In other embodiments, the thumb is relatively rough and is readily visible under the same magnification (e.g., 50 < to 100><>) for distinguishing the shape of the thin moon. Therefore, the grid used to provide security features to the marking sheets need not be optically active in the visible portion of the spectrum. " In a particular embodiment, the matrix pigment particles are mica flakes coated with a layer of TiO 2 or other μ electrical material. The coating material typically has a relatively high refractive index. Mica is relatively inexpensive and easy to process into a natural product of a thin substrate. 126980.doc -19- 200922808 〇When each mother substrate is coated with a coating, it is 彳 播 柘Μ # # The yttrium refractive index material is replaced by W". The mica thin-film substrate can be replaced by a variety of processes, and various processes are used to dry the foundation." It is called "mica is the original, so it is necessary to use ... L photocopying It appears that the pigment flakes based on the current safety special iron mica provide a wide range of special features. However, it is not practical to provide symbols on the mica sheet substrate. According to the present invention, the base sheet is mixed with the mica-based pigment to make the case concealed.., ^ The mouth is so that the child can hide the security feature. 7. The mica-based pigment sheet is printed. In the image. If the thickness of the concealed pigment flake is about five times that of the one-eighth wavelength optical thickness ("QW0T") at the two-light wavelength, the dot-shaped extension 4 such as = inorganic dielectric material is used. The formed pigment flakes of the early layer (4) I have a pigment similar to that of the pigment of 2. Typically, the thickness of a single layer of concealed sheets used to match the mica-based (four) view is from about 6 〇 to about _:. Sheets processed from deposited substrates having a diamond-like pattern tend to have lower yields than corresponding metal dielectric sheets. Fig. 3B is a simplified cross-sectional view of the sheet 2() of the actual & The reflective layer 22 is interposed between the two dielectric film layers 24,%. The dielectric film layers 24, 26 provide hardness to the bright pigment flakes 2's and promote removal of the face(s) from the roll coater substrate. The thickness of the bright pigment flakes is maintained to be less than 1 micron to provide a composition that dries or cures to a smooth surface. In a particular embodiment, the thickness of the sheet is between about "destroyed rice and about 3 microns. The thinner sheet is too small to be more difficult to process and handle" and the thicker sheet is stronger and therefore more difficult. The circular shape is broken along the border. 126980.doc •20· 200922808 The reflective layer 22 is typically a highly reflective metal such as aluminum, platinum, gold, silver or copper or a thin reflective layer of moderately reflective metal such as iron or chromium. Thick to be opaque (reflective) in the visible portion of the spectrum, but not so thick as to interfere with the separation of the film layer from the substrate and subsequent processing into a sheet. In other words, the overly thick metal reflective layer will be between the relatively fragile dielectric layers 24, 26. A ductile layer is provided therebetween and it tends to interfere with the processing of the deposited layers into flakes. Suitable materials for the dielectric layer include, inter alia, ZnS, MgF2, SiO 2 , A 120 3 , TiO 2 , Nb 2 〇 5 and Ta 2 〇 5. In some embodiments The dielectric film layers 24, 26 also provide environmental protection for the reflective layer 22. The bright flakes 20 have a selected shape and optionally have other indicia such as a surface (grid) pattern or elemental fingerprint. The bright flakes 20 are added to the chromogenic pigments and chromogenic compositions (e.g., inks and paints). The formed glitter flakes can be added as a hidden security feature to the substrate (i.e., randomly formed or otherwise formed) bright flakes. It is a simplified cross-section of a bright sheet 2〇 with an elemental indicator layer 28. The bright sheet 20' has a reflective layer 22, 22'' between the dielectric layers 24, 26, and the layer 28 provides an elemental indicator. The element indicator layer 28 is a layer of material not found in the matrix pigment that will be used in conjunction with the bright flakes and using, for example, secondary ion mass spectrometry ("SIMS") analysis, energy dispersive X-ray (EDX) analysis. And the elemental analysis technique of Auger analysis is easy to detect. In addition, the element indicator is present in the concealed sheet but not in the matrix sheet, and micro SIM, micro EDX or micro-ag analysis can easily detect this The difference is that the addition of the finger # element (for example, adding a small amount of a compound containing the indicator element to the carrier) cannot overcome this safety feature 126980.doc -21- 200922808.

The element indicator layer 28 is not optically active because it is interposed between the two opaque reflective layers 22, 22, . The reflective layers 22, 22 are selected to be the same material used for the substrate sheet, such as aluminum. Suitable materials for the element indicator include, inter alia, platinum, rhodium, iron, vanadium, cobalt and tungsten. Those skilled in the art will appreciate that the materials that are often used will depend on the matrix pigments they will be used with. In an alternative embodiment, the reflective layer of bright pigment is the elemental indicator material (see figure, reference numeral 22). For example, a concealed bright or chromogenic pigment flake using platinum as a reflective layer is mixed with a substrate bright & chromogenic pigment flake using aluminum as the reflective layer. In another embodiment, the amount of flakes of the elemental indicator having a blend or blend of pigments is selected to provide a selected elemental ratio (e.g., aluminum and platinum) in the pigment mixture. In an alternative or alternative embodiment, the material of the dielectric thin layer 24, 26 (Fig. 3A, reference numeral 24, selected to provide an elemental indicator. Fig. 3D is a color change according to another embodiment of the present invention). A simplified cross-section of the pigment flakes. The color-changing (four) sheet 30 is commonly referred to as a symmetric 5-layer Fabry-Perot interference sheet. The film stack 32 includes a reflective metal layer 34, two separation layers 36, 3, and two absorption layers 38. , 38 Β "and the layer is usually a transparent transparent chrome, carbon or other material layer. The reflective layer, the separation layer and the absorbing layer are all optically active '', that is, their optical performance for the color-changing pigment flakes; Each side provides a similar Fabry-Perot interference structure to the incident light, and thus the sheet is optically symmetric. Alternatively, the color changing pigment sheet is a full dielectric pigment sheet or a 3-layer sheet, such as an absorber layer/dielectric layer/ Absorbing layer. As is well known in the art of light pigmenting, the color and color of the pigmented flakes are 126980.doc • 22-200922808 by the optical design of the bracts, ie the materials of the layers in the film stack 32 Thickness to determine. Color change pigment thin The optical design of the sheet is typically selected to match the optical properties of the matrix pigment flakes to which it is blended. The color changing pigment sheet 30 is formed (see Figure 3A, reference numeral 18), and optionally includes, for example, a surface grid pattern And/or other indications of the element indicator.

For example, the reflective layer includes an elemental indicator that is a reflective metal different from the matrix pigment flakes or that includes one or more additional element indicator layers that may or may not be optically active (see Figure 3C, reference numerals) 28). Alternatively or additionally, the separator layers 36A, 36B and/or the absorbent layers 38A, 38B comprise an element indicator. For example, if the matrix pigment flakes use MgF2, Si〇2 or Ah〇3 as the separator material, the concealed pigment flakes 3 〇 use different separator materials such as Dings 2 or ZnS. Separating and/or absorbing indicator materials include elements that are readily detectable using elemental analysis. In some implementations, the use of different separators and/or reflective materials produces a concealed pigment flake 30 having optical properties different from those of the substrate flakes. That is, even if the concealed and matrix sheets are similar at normal incidence; the color path can be different. In general, low refractive index spacer materials (such as he and 〇2) provide a higher specific refractive index separation material (such as ZnS and TiO2): color range ("fast change" pigment). However, the concealed flakes can be added to the matrix pigment flakes in a phase-integration 'even if the color distance does not exactly match the brace of the matrix flakes, one of the present inventions," the observer cannot detect the difference.

Experimental Results Manufacture and measure the test standard using 100% violet and red 'green light-recessed ("〇νι) pigment flakes. Both bright and photo-labeled samples have a grid pattern f' of 2' lines per mm which makes the marking sheets more easily distinguishable from the matrix pigment sheets (thinking of the jaws) and more difficult to counterfeit. The grid pattern was clearly visible under Jochen X and did not induce visible light diffraction properties in the images printed with the test compositions. It is believed that the lower portion of the marking sheet is not well oriented to the observer to avoid diffraction. In an alternative embodiment, the finer grid pattern is included on the shaped marking sheet. These shapes are identifiable at the first magnification of the microscope 'but the grid pattern is not easily visible at this first magnification. The grid pattern is visible at higher magnifications. It is believed that including a marking sheet having a selected shape or symbol to include the grating pattern further enhances the concealing nature of the marking sheet because the counterfeiter may see the shape or symbol under the microscopic examination but may not see the grating pattern and thus in the counterfeit article Does not include the grille pattern. The first test sample ("sample r") contains 9% (by weight) of the mixture of 1% by weight (by weight) of the magenta to green (10) pigment flakes ("marked flakes") having a grid (see) Matrix red to green pigment flakes. These marking flakes are easily detected by conventional microscopy using 126980.doc •25-200922808, and the test is the same as the test standard, because 樟$ " ^ ^ matches.

Illustrative Method FIG. 6 is a diagram of a method 600 for fabricating a pigment flake according to an embodiment of the present invention. A roll of substrate having a selected deposition table 126980.doc -26-200922808 of the roll substrate is provided. Area ratio of unscented flowers (" a smooth ") portion and an embossed portion (step 602). In one embodiment, the pressure/mesh female π knives are embossed with a frame for a sheet having a serpentine shape. In an alternative embodiment The middle part is patterned by a thumb pattern or a symbol factory. It is patterned using a ruthenium other than embossing, such as laser cutting. At least one film layer is deposited on the roll substrate (step 604), ' The deposited one or more film layers are processed into a sheet (step 606) to produce a sheet of the label having a % Η AU ^ selection: the sheet yield is determined by, for example, the type of film layer being processed, Depending on the nature of the border, the pattern of the grid or the symbols and the parameters of the processing parameters. For example, referring to Figures 2A and 2B, if 1% of the surface of the roll substrate is embossed by a grid or symbol ', then a yield of about 1% of the marked sheet having a grid pattern or symbol is expected. If the scratched surface of the roll substrate is a diamond-shaped frame, a yield of about 9% is expected for a dielectric-metal-dielectric sheet because there is a yield of 1% when processing the patterned portion of the film stack into a formed sheet. loss. Similarly, about 5% yield is expected for forming full-scale singulation; 1 electro-thin film is expected because of the loss of yield when processing the patterned portion of the film stack into shaped sheets. Although the invention has been described above with respect to various specific embodiments, it will now be described that one aspect of the invention that provides a significant advantage. For example, the present invention, which provides a significant advantage, is an embodiment in which a frame or border of a symbol or a border with such a border is used on a substrate material for forming a coating thereon. . Turning now to Figure 7, a photograph of a thin layer of a plurality of euro symbols is shown, wherein each of the symbols on the thin layer has an embossed border surrounding it. This usually borrows 126980.doc •27- 200922808

This is accomplished by embossing an organic substrate such as a pet substrate with a border symbol, and then coating the substrate with a removable coating. Figure 8 is a photograph of the sheets separated from their base or substrate. This photo clearly shows that most symbols are integers, where few cracks appear to enter or pass through the symbols. By making = the invention, a very small portion of the sheet is broken in such a way that the symbol of the symbol is blurred. However, it is shown that the border does not exist along all sides of the sheet after the sheet has broken from the substrate on which it is deposited. - Some sheets have no boundaries and other sheets may have one and up to four boundaries. However, this is understandable. Since the border border separates the sheet from its nearest sheet, the boundary typically remains attached to a sheet and its adjacent sheet on the other side of the border of the border, when the sheet is separated. However, the presence of this border boundary causes most of the sheets to break at one side or the other side of the border line, providing a relatively uniform sheet with relatively straight edges. Typically, each of the signed 1-sheets will have at least a boundary or frame portion attached thereto after being separated from the web or substrate on which it is deposited. Preferably, the frame is easier to cut than other portions of the sheet. Figure 9 is a photograph of a plurality of Mg_Gn flakes carrying μ symbols in which stress cracks due to lack of a bezel and results in a distinct random break line, so that the flakes randomly break some symbols and destroy other symbols. Figure 9 illustrates the stress cracks throughout the sheet: due to the effect of such cracks, which cause thinning & the crack continues to appear in the sheet thereby blurring the sign. According to the present invention, the provision of the bezel does not completely prevent stress cracking, however, it is provided that the cracks can be controlled to a greater extent to be broken along the bezel line 4 or preferentially along the bezel line. In contrast to Fig. 9, an embodiment of the invention, shown in conjunction with Fig. 7 and showing, can be separated in a manner along the pre-126980.doc -28-200922808 boundary, thereby retaining a higher degree on the sheet. The shape and integrity of the symbols and generally do not obscure the hidden symbols in the sheet. Cracks that appear in unframed symbols appear and expand in more fragile, glass-like dielectric materials, but along Figure 7 The border line provided in the thin layer showing the symbol of the border is stopped and the path is changed to continue its expansion. The bezel is provided to cause the sheet to preferentially rupture along the border line. Most of the cracks observed in the sheet of Fig. 8 do not completely pass through. The total thickness of the sheet, which stops at the more elastic metal core (Al/Ni/Al) level of the sheet, creates a masking effect that is detrimental to the clarity of the original embossed symbol. The sheets in Figures 8 and 9 are approximately 1300 nm or ι·3 μm thick and has the following layer structure: 10 nm Cr/480 nm MgF2/80 nm AI/50 nm Ni/80 nm A1 480 nm MgFVlO nm Cr. There is a magnetic layer that provides the appearance characteristics. Turning now to Figure 10, it is missing a lot A photograph of a plurality of bordered symbols in a hidden symbol or a frame of a border, wherein the ratio of the symbol of the bordered frame to the other sheets is 1:1. There are two interesting aspects of this embodiment. At the detection level, it is equipped with 1 〇〇><Handheld Microscope can detect the presence of a hidden sheet with a Euro symbol, and in addition, it can quickly estimate the ratio of hidden and non-concealed symbols to approximately: In addition, it compares the ratio of square symbols to randomly shaped sheets to provide some measure of the identification. Thus, the shape, distribution, and identification of the symbols within the shape of the border can be used to determine the coating within a certain range of confidence. Whether the layer is believable. Although the sheet with the symbol enclosed by the border or border is usually broken into the desired shape along the border line or groove, as indicated by the euro with the border in Figure 1 , ', 126980.doc •29- 200922808 c There is a case where the sheet is undesirably broken along the embossed line forming the symbol. See > See Figure 11 a 'Showing the cut surface of the substrate u 仅 which is only a part of the array' More specifically, one can be seen a substrate of the entire sheet and a portion thereof adjacent thereto (other sheets are formed in the crucible). In this exemplary embodiment, 'because the character needs to be carried, JDSU', and the border or border frame of the attached label along the border U1 The breakage is such that the shape of the sheet is square, so the depth of the groove 形成 forming the boundary or the frame 1 1 1 is substantially deeper than the groove forming the mark 丨i 2 or the text 113. Preferably, the ratio of the depth of the bezel to the depth of the logo or text is at least 10:8 and preferably greater to ensure that the web is broken and severed along the border of the bezel, i.e., within the bezel of the bezel. Figure 11b is a cross-sectional analysis indicating the relative depth of embossing on the substrate. The groove of the frame is U-shaped and wider than the V-shaped and narrow groove defining the mark and the letter. Preferably, the coating material which coats the substrate and forms the sheet fills the grooves of the characters and logos more than the grooves of the filling frame. This increases the rupture of the bezel and reduces the rupturability of the grooves along the defined text or logo. Figure 11c corresponds to Figures Ua and Ub and is a normal view of the substrate. In contrast to Figure 11a, Figure 11d is a substrate having a mirrored relief wherein the bezel is defined by a wall and wherein the text and logo protrude from the bottom of the substrate. The figure shows the relative height of the walls and Figure Uf is the normal view of the substrate. The logo and bezel are still defined by the wall when the thin layer of the sheet is removed from the substrate. Figure 12a is a cross-sectional view of a prior art framed sheet wherein the grooves defining the indicia in the form of letters or logos have the same depth as the grooves defining the frame. Although the full double-walled u-shaped frame is shown to illustrate the difference between Figure i2a and Figure 1沘126980.doc -30- 200922808, but in the slice from the 1-wall u-frame, this is because:: "From the back 'usually will not Four sheets with double-twisted mouth horses should be indicated along the edge when the sheet is separated from the substrate = the dotted line is shown because of the groove in Figure 12a: the position at which the sheet will be severed. However, it is very likely that you will be thin and sloppy, and you can see the 'definite symbol _ as observed in the uniform phase 12b ^ ^ The width or depth of the groove is about the height or depth of the groove defining the frame. . m half, that is, the border is darker than the symbol.

For an extremely inclined trajectory, the opening of the groove in the deeper groove will have a coating that is thinner than the bottom. This is desirable in the case where the sheet is broken along the groove. The higher the ratio, the greater the difference between the features at the bottom, top and sidewalls. This phenomenon is well known in the fabrication of semiconductor devices having high aspect ratio features. Flake fracture can occur via different mechanisms. Doc 31 - 200922808 The damage is produced by applying a shearing force to the surface of the sheet by the application of shearing force to the sheet: the second: the fracture of the raw. The cut is produced by applying a vertical force to the surface of the sheet: The impact is due to a combination of these mechanisms. This ... h (four) pass hang w can be returned to the health. For example, material grinding can be ... ink: Α ... necessary liquid phase mixing operation occurs. Mechanically induced wear and tear By the time of application, at this time; the cut is usually printed on the letterpress m, passing through the division. An example of this is to force the Ml ΰ application in the squeegee during flexo printing or concave. Rotating screen application pattern: == When the sieve is used, the sheet and the web in the ink are called “knife grinding method”: interaction. This interaction is similar to the method used by “knife=.” The grinding effect is obtained by the rotation assembly of the particles. The impact grinding can be performed by interacting with other sheets or with the rear equipment: high-speed mechanical interaction. Sex will be concentrated on the non-homogeneous load distribution The load distribution of the load is shown in Figure 14a. There is a local difference depending on the position of the two "rupture points (regions) applied and 4 5 'right is considered to be grinding; fg; l appears at the bottom = two fractures' Then the cut on the bottom of the deep feature indicated by area 1... The micro-cosm of the bottom of the shadow feature shown in area 2 of Figure 14b, in addition, as explained above, the 'expected deep feature' - the break, the alpha-conformity shadow The microstructure of the features is more fragile. Although the present invention provides a means for causing the sheet to break along the border line rather than along the line or 126980.doc -32.200922808, the embodiments described below protect the sheet from separation after separation of the sheet from the substrate to prevent It is not necessary to break further. Figure ^5 shows a sheet that has been encapsulated in a protective coating. In this example, a thin sheet can be passed through a high dielectric index material (such as ZnS,

The coated or dielectric/metal multilayer sheets of Ti02, SiOx, Al2〇3, etc. can be coated with a semi-transparent material (such as a sol-gel (si〇x)) that enhances the symbolic observation. If the sheet is made of a low refractive index material of η <1.65, then encapsulating the sheet with a high refractive index material (i.e., η greater than or equal to U5) can produce a microstructured sheet having dichroism. A stack of alternating/low/咼 all dielectric layers of a shaped/signed wafer having a concealing function and similar to the visual optical effect of the light pigment is formed. Advantageously, the packaging process will not only improve the durability of the sheet, but also provide additional functionality to the microstructured sheet. It is well known to be compatible with vacuum vapor deposition (PVD or CVD) and is non-surface compatible by sol-gel or other wet chemical methods. By way of example, this is used in ophthalmic optical coatings to mask scratches or other surface imperfections during the molding process. In a wet chemical process, a non-four-day six & phase-grain coating will tend to fill the voids such as grooves present in the embossed sheet, reducing the non-uniform load that is already on the fragile area of the sheet. Thereby improving the fracture properties. In some cases, the compatible coating will have a coating of substantially the same thickness at various locations different from the substrate microstructure deposited by the (etc.) layer. An incompatible coating (such as a wet chemical coating) will have a tendency to fill the gaps in the microstructure and thus "flatten the sheet". This is extremely advantageous 'because it provides embossing of the flakes for visible visual effects The benefit of 'and where the flakes are then planarized in a manner that preserves or enhances the effect of the 126980.doc -33 - 200922808 effect.

ItC ^ does not enter the "edible flakes" of the pharmaceutical industry's specific applicability. Many FDA approved materials for consumption "edible flakes" include dielectric materials such as &

TiOx, A10x, Fe0 However, such materials are more brittle than metals or polymeric materials and have been found to be made according to the teachings of the present invention, as is more generally known to produce ''meal'" or " edible Sheets, where the borders are more susceptible to breakage than marks in the sheets, and coating such more fragile sheets with a sol-gel or other protective coating is highly advantageous in preventing some otherwise breakage that may occur during post processing. Improvements in fracture properties are also seen in sheets coated with a translucent ductile material by a packaging method. In this case, the sheet is coated by depositing a thin layer of soft translucent polymeric material under vacuum. An appropriate deposition method is the electricity table polymerization described. This method is well known for coating, butan, % or COxHy, which is a variation of plasma enhanced chemical vapor deposition (CVD) of Si〇2, Ti〇2 and diamond-like carbon. In addition, some polymers may be vaporized by physical vapor deposition or even sputtered to create a function of microstructured concealed indicia or to improve their durability.
