Description

Technical Field

[0001] This invention relates to the field of anti-counterfeiting technology, and more specifically, to an anti-counterfeiting element, a method for manufacturing an anti-counterfeiting element, and an anti-counterfeiting product. Background Technology

[0002] In the anti-counterfeiting market, existing polymer substrates mainly come in three forms: paper-plastic paper, plastic-paper-plastic, and pure polymer. Existing composite substrates all involve bonding different layers of substrates together to form a multi-layered structure. The first two forms, however, suffer from poor bonding between layers, leading to potential separation. Pure polymer applications, on the other hand, are costly. This invention creates a composite effect within a single-layer substrate structure, both tactilely and visually. The process is simple, with the polymer body and paper fibers seamlessly integrated, blurring the paper-plastic boundary. This anti-counterfeiting element has strong adhesion to paper, making it difficult to detach. Security items such as banknotes and securities made from this type of anti-counterfeiting paper exhibit strong anti-counterfeiting capabilities, effectively preventing counterfeiters from copying and imitating them. Security paper containing this paper-plastic composite anti-counterfeiting element can also simultaneously contain watermarks, security threads, and other anti-counterfeiting fibers, or combinations thereof, further enhancing its anti-counterfeiting performance. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] In view of this, a first aspect of the present invention is to provide an anti-counterfeiting element.

[0005] A second aspect of the present invention is to provide a method for manufacturing an anti-counterfeiting element.

[0006] A third aspect of the present invention is to provide an anti-counterfeiting product.

[0007] In view of the above, according to a first aspect of the present invention, an anti-counterfeiting element is provided, comprising: a substrate, the substrate comprising paper fibers; a polymer body formed on the substrate; the polymer body comprising an organic material embedded in the paper fibers; the polymer body further comprising an anti-counterfeiting material located within the organic material, wherein the anti-counterfeiting material is used to form an anti-counterfeiting pattern with composite anti-counterfeiting function; the transmittance of the substrate in the visible light band is a first transmittance; the transmittance of the polymer body in the visible light band is a second transmittance; the ratio of the second transmittance to the first transmittance is greater than or equal to 1.5.

[0008] The anti-counterfeiting element provided in this application includes a substrate and a polymer body. The substrate includes paper fibers, that is, the substrate is a paper substrate, which can be paper. The polymer body is formed on the substrate, that is, the polymer body is formed at any part of the substrate. The polymer body is a paper fiber-based composite material made of high-molecular polymer materials. The polymer body includes organic materials, which are infiltrated into the paper fibers to form a single-layer substrate structure, achieving the effect of a composite substrate. This allows the polymer body and paper fibers to be perfectly connected, blurring the paper-plastic boundary. By embedding the organic materials in the paper fibers, the organic materials have a strong bond with the paper substrate and are not easily detached from the paper substrate. The polymer body also includes anti-counterfeiting materials, which are located within the organic materials. These anti-counterfeiting materials form an anti-counterfeiting pattern with composite anti-counterfeiting functions. Specifically, the polymer body may contain anti-counterfeiting materials. The organic materials and anti-counterfeiting materials are mixed to generate a photoreactive solution. The photoreactive solution is then applied or dripped onto the target area of ​​the substrate, allowing the photoreactive solution to penetrate into the interior of the target area, that is, the gaps between the paper fibers. Then, the target area is exposed to a light source of a certain wavelength using a preset pattern, causing the photoreaction solution to undergo a cross-linking reaction to form a polymer body. The pattern polymer is then developed using a wet or dry process to form an anti-counterfeiting pattern with composite anti-counterfeiting function on the polymer body.

[0009] Furthermore, the transmittance of the substrate in the visible light band is defined as the first transmittance, and the transmittance of the polymer body in the visible light band is defined as the second transmittance. The ratio of the second transmittance to the first transmittance is greater than or equal to 1.5. That is, the polymer body has a certain transmittance in the visible light band, and its transmittance is at least 1.5 times that of the surrounding substrate area. Therefore, under conditions of sufficient transmittance, observing the polymer body on the substrate allows one to see the pattern and / or anti-counterfeiting pattern of the polymer body, thereby increasing recognizability and improving anti-counterfeiting capabilities.

[0010] The anti-counterfeiting element of this invention embeds organic materials into paper fibers, with the anti-counterfeiting material located within the organic materials. This process utilizes the anti-counterfeiting material to form an anti-counterfeiting pattern, thereby improving the bonding force between the polymer body and the substrate. This makes it less likely to detach from the substrate. Security items such as banknotes and securities made from security paper with this type of anti-counterfeiting element have strong anti-counterfeiting capabilities and can effectively prevent counterfeiters from copying and imitating them, thus further improving anti-counterfeiting performance.

[0011] In addition, the anti-counterfeiting element provided in this application may also have the following additional technical features:

[0012] In some technical solutions, the anti-counterfeiting materials may optionally include at least one or a combination of dyes, energy storage luminescent materials, fluorescent materials, ultraviolet luminescent materials, infrared luminescent materials, photochromic materials, electrical signal materials, Raman materials, trace materials, acid-sensitive materials, and thermochromic materials.

[0013] In this technical solution, the anti-counterfeiting material can be at least one or a combination of dyes, energy storage luminescent materials, fluorescent materials, ultraviolet luminescent materials, infrared luminescent materials, photochromic materials, electrical signal materials, Raman materials, trace materials, acid-sensitive materials, and thermochromic materials, wherein trace materials include DNA materials.

[0014] In some technical solutions, the organic material is optionally composed of a photoinitiator, a heat-removable and / or water-washable photocurable material, and / or a UV absorber; wherein the photoinitiator accounts for no more than 8% of the mass fraction of the photocurable material.

[0015] In this technical solution, after the organic material is exposed to an exposure light source, it undergoes a corresponding photochemical reaction. After the reaction, due to molecular polymerization or cross-linking, a solid material that cannot be heated and volatilized is formed. By removing the uncured organic material through appropriate temperature and / or water washing, the edge shape of the generated anti-counterfeiting paper pattern can be controlled by the pattern design of the mask. At the same time, due to the plasticity, fiber-forming, and film-forming properties of the organic material after the reaction, the edge shape of the generated patterned anti-counterfeiting window can be controlled by the pattern design of the mask, making the edges clearer and sharper, and the pattern more refined, thus having a higher degree of recognition and enabling the anti-counterfeiting paper pattern to achieve an effective anti-counterfeiting effect.

[0016] Further, the organic material includes a photoinitiator, a heat-removable and / or water-washable photocurable material, and / or a UV absorber. The photoinitiator can be a pyrolytic photoinitiator, a hydrogen-abstracting photoinitiator, or a cationic photoinitiator. Pyrolytic photoinitiators can include benzoin-based photoinitiators, benzoyl-based photoinitiators, acetophenone-based photoinitiators, α-hydroxyketone-based photoinitiators, α-aminoketone-based photoinitiators, benzoylcarbamate-based photoinitiators, and acylphosphine oxide-based photoinitiators; hydrogen-abstracting photoinitiators can include benzophenone-based photoinitiators, thioxanthone-based photoinitiators, and anthraquinone-based photoinitiators; cationic photoinitiators can be thioonium salt-based photoinitiators and iodonium salt-based photoinitiators. Further, pyrolytic photoinitiators are preferred, and acylphosphine oxide-based photoinitiators are more preferred. The above-mentioned photoinitiators should be organic compounds and the amount added should not exceed 8%, more preferably not exceeding 5%. Because small amounts of specific photoinitiators can form azeotropes with easily volatile (evaporating), water- and other solvent-soluble photocurable materials, they are easy to remove. However, if unsuitable photoinitiators, such as ferrocene photoinitiators, are used, removal is difficult. Furthermore, excessive amounts of photoinitiators also hinder removal. Therefore, it is necessary to control the type and amount of photoinitiator used.

[0017] In some technical solutions, the photocurable material component may optionally be selected from at least one of compounds in acrylate systems, methacrylate systems, acrylamide systems, N-vinyl systems, thiol-olefin systems, thiol-acetylene systems, vinyl ether systems, oxetane systems, and epoxy systems.

[0018] In this technical solution, the photocurable material component is selected from at least one compound chosen from acrylate systems, methacrylate systems, acrylamide systems, N-vinyl systems, thiol-olefin systems, thiol-acetylene systems, vinyl ether systems, oxetane systems, and epoxy systems, with acrylate systems, methacrylate systems, acrylamide systems, and N-vinyl systems being preferred. Furthermore, the molecular weight of any component of the photocurable material should not exceed 328 g / mol. Therefore, the components of photocurable materials can be tetrahydrofurfuryl methacrylate (THFMA), cyclotrimethylolpropane methyl acetal methacrylate (CTFMA), isobornyl methacrylate (IBOMA), benzyl methacrylate (BMA), 2-phenoxyethyl methacrylate (PHEMA), 1,6-hexanediol dimethacrylate (HDDMA), 1,4-butanediol dimethacrylate (BDDMA), dipropylene glycol dimethacrylate (DPGDMA), tripropylene glycol dimethacrylate (TPGDMA), neopentyl glycol dimethacrylate (NPGPO2DMA), neopentyl glycol dimethacrylate (NPGDMA), etc., and can also be tetrahydrofurfuryl acrylate (THFA), cyclotrimethylolpropane methyl acetal acrylate (CTFA), isobornyl acrylate (... Examples of acrylamides include IBOA, benzyl acrylate (BA), 2-phenoxyethyl acrylate (PHEA), 1,6-hexanediol diacrylate (HDDA), 1,4-butanediol diacrylate (BDDA), dipropylene glycol diacrylate (DPGDA), tripropylene glycol diacrylate (TPGDA), 2-propenyloxyneopentyl glycol diacrylate (NPGPO2DA), and neopentyl glycol diacrylate (NPGDA). Other acrylamides include 4-acryloylmorpholine (ACMO), dimethylacrylamide (DMAA), diethylacrylamide (DEAA), isopropylacrylamide (NIPAM), dimethylaminopropylacrylamide (DMAPAA), hydroxyethylacrylamide (HEAA), and diacetone acrylamide (DAAM). N-vinylcarbazole, N-vinylpyrrolidone, and N-vinyl-2-caprolactam are also available. Preferably, combinations of monofunctional and difunctional monomers or difunctional monomers are preferred to achieve better physicochemical resistance.

[0019] In some technical solutions, optionally, the polymer body is formed at any part and in any shape on the substrate. The shape of the polymer body includes at least one or a combination of Chinese characters, numbers, letters, polygons, circles, lines, QR codes, moiré patterns, moiré stripes, coded patterns, and grayscale patterns.

[0020] In this technical solution, the polymer body is formed in any shape on any part of the substrate. The shape formed by the polymer body can be Chinese characters, numbers, letters, rectangles, squares, circles, bars, pentagons, thin lines, patterns, numbers, QR codes, moiré patterns, moiré stripes, or other coded patterns with varying shades of gray. By forming the polymer body in any shape on any part of the substrate, different anti-counterfeiting patterns can be created on the substrate, applicable to different anti-counterfeiting products, thus broadening the application range. Furthermore, the complexity of the pattern further enhances the anti-counterfeiting performance.

[0021] In some technical solutions, the anti-counterfeiting pattern may optionally include at least one or a combination of Chinese characters, numbers, letters, polygons, circles, lines, QR codes, moiré patterns, moiré stripes, coded patterns, and grayscale patterns.

[0022] In this technical solution, the anti-counterfeiting pattern is formed on the substrate in any shape, such as Chinese characters, numbers, letters, rectangles, squares or circles, bars, pentagons, thin lines, patterns, numbers, QR codes, moiré patterns, moiré stripes or other forms of coded patterns, patterns with a certain level of grayscale, etc. Because the anti-counterfeiting pattern is formed on the substrate in any shape, different anti-counterfeiting patterns can be formed on the substrate and applied to different anti-counterfeiting products, making the application range wider. Furthermore, the more complex the anti-counterfeiting pattern, the higher its anti-counterfeiting performance.

[0023] It is understandable that the shape of the polymer body on the substrate can be the same as or different from the anti-counterfeiting pattern.

[0024] In some technical solutions, the anti-counterfeiting pattern can optionally be in the shape of lines, with a width greater than or equal to 50μm and a line width precision in the range of 20μm to 120μm.

[0025] In this technical solution, the anti-counterfeiting pattern can be presented as fine lines, with a line width, i.e., line fineness, ranging from less than 50μm to more than 1000μm. Furthermore, when the anti-counterfeiting pattern is a fine line, the line width fineness must be greater than 20μm and less than 120μm.

[0026] In some technical solutions, alternatively, there may be a corresponding relationship between anti-counterfeiting patterns, which can be superimposed to form a new anti-counterfeiting pattern.

[0027] In this technical solution, the anti-counterfeiting element can contain multiple anti-counterfeiting patterns, and there can be a certain correspondence between the multiple anti-counterfeiting patterns. They can be superimposed on each other to generate new anti-counterfeiting patterns, forming a self-inspection, which also makes it convenient for users to verify anti-counterfeiting.

[0028] In some technical solutions, the substrate may optionally be pure paper; or the middle of the substrate may be a transparent plastic substrate, and the two sides of the substrate may be paper; or one side of the substrate may be paper, and the other side of the substrate may be a plastic substrate.

[0029] In this technical solution, the substrate can be pure paper, or it can be a "sandwich" paper composed of a transparent plastic substrate in the middle and paper on both sides, or it can be paper with paper on one side and a plastic substrate on the other side.

[0030] The second aspect of the present invention provides a method for manufacturing an anti-counterfeiting element, comprising: mixing organic materials and anti-counterfeiting materials to obtain a photoreactive solution; penetrating the photoreactive solution into a target area on a substrate; exposing the target area to obtain a polymer body in the target area; and developing the polymer body to form an anti-counterfeiting pattern on the polymer body.

[0031] The anti-counterfeiting element manufacturing method provided by this invention first involves mixing organic materials and anti-counterfeiting materials to generate a photoreactive solution. Then, the photoreactive solution is applied or dripped onto a target area on a substrate, allowing it to penetrate into the interior of the target area, specifically the gaps between paper fibers. Next, the target area is exposed to a predetermined pattern using a light source of a specific wavelength, causing the photoreactive solution to undergo a cross-linking reaction to form a polymer body. Finally, the pattern polymer is developed using a wet or dry process to form an anti-counterfeiting pattern on the polymer body.

[0032] Specifically, a photoreactive material is placed on the target area of ​​a paper substrate and allowed to penetrate into the substrate; the substrate is exposed with a preset pattern to cause the photoreactive material to undergo a cross-linking reaction to form a polymer body; finally, the pattern polymer is developed using a wet or dry process to form an anti-counterfeiting element with a polymer body.

[0033] The polymer body of the anti-counterfeiting element of the present invention has a strong bond with the substrate and is not easy to fall off the substrate. The banknotes, securities and other security items made of security paper with this anti-counterfeiting element have strong anti-counterfeiting capabilities and can effectively prevent counterfeiters from copying and imitating them. The security paper containing this paper-plastic composite structure anti-counterfeiting element can also contain one of watermarks, security threads and other anti-counterfeiting fibers as well as combinations thereof, to further improve the anti-counterfeiting performance.

[0034] In some technical solutions, the developing process may optionally include: wet developing process and / or dry developing process.

[0035] In this technical solution, the development process can be wet development, which involves developing the polymer substrate through methods such as water washing or solvent washing. Alternatively, it can be dry development, which involves developing the polymer substrate through methods such as evaporation, infrared drying, or high-temperature drying. By developing the polymer substrate, an anti-counterfeiting pattern is formed on it.

[0036] In some technical solutions, optionally, the wavelength range of the exposure process is greater than or equal to 195nm and less than or equal to 1650nm.

[0037] In this technical solution, the wavelength range of the exposure light source is greater than or equal to 195nm and less than or equal to 1650nm, that is, the wavelength range is 195nm to 1650nm. The exposure light source is either infrared or ultraviolet light.

[0038] Furthermore, the polymer bulk is detected using detection equipment; the detection equipment includes at least one or a combination of a sensor, an excitation source, an imaging device, and a transmission spectrometer.

[0039] Specifically, the testing equipment is used to inspect the polymer itself and determine whether the anti-counterfeiting elements are qualified. The anti-counterfeiting elements can exhibit obvious anti-counterfeiting feature signals under the corresponding testing equipment, thereby improving the anti-counterfeiting effect and the concealment effect.

[0040] The detection equipment includes: a sensor, which includes at least two of ultraviolet sensors, infrared sensors, magnetic sensors, and capacitive sensors, used to acquire anti-counterfeiting feature signals in the anti-counterfeiting element; an excitation source and an imaging device, used to acquire the anti-counterfeiting feature network pattern in the anti-counterfeiting element and / or to acquire the optical contrast between the anti-counterfeiting medium layer and the transparent material layer in the anti-counterfeiting element, wherein the excitation source includes a transmission light source and / or a reflection light source, and the imaging device includes a high-resolution imaging device; and a transmission spectrometer, used to observe the anti-counterfeiting element.

[0041] Understandably, under a certain wavelength of light, the polymer itself can change color or emit light in order to detect obvious anti-counterfeiting feature signals.

[0042] The third aspect of the present invention provides an anti-counterfeiting product, comprising: an anti-counterfeiting element as described in any of the technical solutions of the first aspect above.

[0043] The anti-counterfeiting product provided by the technical solution of the present invention includes anti-counterfeiting elements as described in any of the technical solutions of the first aspect of the present invention, and therefore has all the beneficial effects of anti-counterfeiting elements as described in any of the technical solutions of the first aspect of the present invention, which will not be repeated here.

[0044] In some technical solutions, optionally, the number of anti-counterfeiting elements is multiple, and multiple anti-counterfeiting elements are stacked.

[0045] In this technical solution, when there are multiple anti-counterfeiting elements, multiple anti-counterfeiting elements can be stacked, that is, overprinted together to produce a new anti-counterfeiting element effect, forming a self-check.

[0046] In some technical solutions, the anti-counterfeiting product may optionally include a watermark on the substrate; and / or a security thread on the substrate; a transparent window on the substrate; and / or anti-counterfeiting fibers on the substrate; and / or anti-counterfeiting ink on the substrate; and / or an anti-counterfeiting chip on the substrate.

[0047] In this technical solution, anti-counterfeiting products containing anti-counterfeiting elements can also contain one or a combination of watermarks, security threads, transparent windows, anti-counterfeiting inks, anti-counterfeiting chips, and other anti-counterfeiting fibers to further improve anti-counterfeiting performance.

[0059] 10 Anti-counterfeiting components, 110 Substrate, 120 Polymer body, 1202 Anti-counterfeiting pattern. Detailed Implementation

[0060] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0061] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0062] The following reference Figures 1 to 9 Anti-counterfeiting elements, manufacturing methods of anti-counterfeiting elements, and anti-counterfeiting products are provided according to some embodiments of the present invention.

[0063] This application provides an anti-counterfeiting element 10, comprising: a substrate 110, the substrate 110 comprising paper fibers; a polymer body 120 formed on the substrate 110; the polymer body 120 comprising organic materials embedded in the paper fibers; the polymer body 120 further comprising anti-counterfeiting materials, the anti-counterfeiting materials being located within the organic materials, and the anti-counterfeiting materials forming an anti-counterfeiting pattern 1202 with composite anti-counterfeiting function; the transmittance of the substrate 110 in the visible light band is a first transmittance; the transmittance of the polymer body 120 in the visible light band is a second transmittance; the ratio of the second transmittance to the first transmittance is greater than or equal to 1.5.

[0064] The anti-counterfeiting element 10 provided by this invention includes a substrate 110 and a polymer body 120. The substrate 110 comprises paper fibers, i.e., the substrate 110 is a paper substrate 110, which can be paper. The polymer body 120 is formed on the substrate 110, i.e., the polymer body 120 is formed at any location on the substrate 110. The polymer body 120 is a paper fiber-based composite material made of a high-molecular polymer material. The polymer body 120 includes organic materials that permeate into the paper fibers, thereby forming a single-layer substrate 110 structure, achieving the effect of a composite substrate 110. This ensures a perfect connection between the polymer body 120 and the paper fibers, with a good paper-plastic boundary. By embedding the organic materials within the paper fibers, the organic materials have a strong bond with the paper substrate 110 and are not easily detached from it. The polymer body 120 also includes anti-counterfeiting materials located within the organic materials.

[0065] Specifically, the polymer body 120 may contain anti-counterfeiting materials. Organic materials and anti-counterfeiting materials are mixed to generate a photoreactive solution. This solution is then applied or dripped onto a target area on the substrate 110, allowing it to penetrate into the interior of the target area, specifically the gaps between paper fibers. The target area is then exposed to a predetermined pattern using a light source of a specific wavelength, causing the photoreactive solution to undergo a cross-linking reaction to form the polymer body 120. The pattern polymer is then developed using either a wet or dry process. Different exposure methods result in different patterns appearing on the polymer body 120, forming an anti-counterfeiting pattern 1202 with composite anti-counterfeiting functions.

[0066] Furthermore, the transmittance of the substrate 110 in the visible light band is a first transmittance, and the transmittance of the polymer body 120 in the visible light band is a second transmittance, the ratio of the second transmittance to the first transmittance being greater than or equal to 1.5. That is, the polymer body 120 has a certain transmittance in the visible light band, and its transmittance is at least 1.5 times that of the surrounding area of ​​the substrate 110. Therefore, under the condition of having a certain transmittance, observing the polymer body 120 on the substrate 110 reveals the pattern and / or anti-counterfeiting pattern of the polymer body 120, thereby increasing recognizability and improving anti-counterfeiting capabilities. Furthermore, the transmittance of the substrate 110 in the visible light band is a first transmittance; the transmittance of the polymer body 120 in the visible light band is a second transmittance; the ratio of the second transmittance to the first transmittance is greater than or equal to 1.5.

[0067] The anti-counterfeiting element 10 of the present invention embeds organic material into paper fibers, with the anti-counterfeiting material located within the organic material, thereby forming an anti-counterfeiting pattern 1202. This improves the bonding force between the polymer body 120 and the substrate 110, making it less likely to detach from the substrate 110. Security items such as banknotes and securities made with security paper containing this anti-counterfeiting element 10 have strong anti-counterfeiting capabilities and can effectively prevent counterfeiters from copying and imitating them, thereby further improving anti-counterfeiting performance.

[0068] In some embodiments, the anti-counterfeiting material may optionally include at least one or a combination of dyes, energy storage luminescent materials, fluorescent materials, ultraviolet luminescent materials, infrared luminescent materials, photochromic materials, electrical signal materials, Raman materials, trace materials, acid-sensitive materials, and thermochromic materials.

[0069] In this embodiment, the anti-counterfeiting material may be at least one or a combination of dyes, energy storage luminescent materials, fluorescent materials, ultraviolet luminescent materials, infrared luminescent materials, photochromic materials, electrical signal materials, Raman materials, trace materials, acid-sensitive materials, and thermochromic materials, wherein the trace materials include DNA materials.

[0070] In some embodiments, the organic material may optionally consist of a photoinitiator and a heat-removable and / or water-washable photocurable material, and / or a UV absorber; wherein the photoinitiator accounts for no more than 8% of the mass fraction of the photocurable material.

[0071] In this embodiment, after the organic material is exposed to an exposure light source, a corresponding photochemical reaction occurs. After the reaction, due to molecular polymerization or cross-linking, a solid material that cannot be heated and volatilized is formed. Thus, by removing the uncured organic material through appropriate temperature and / or water washing, the edge shape of the generated anti-counterfeiting paper pattern can be controlled by the pattern design of the mask. At the same time, because the organic material has plasticity, fiber-forming, and film-forming properties after the reaction, the edge shape of the generated patterned anti-counterfeiting window can be controlled by the pattern design of the mask, making the edges clearer and sharper, and the pattern more refined, thereby having a higher degree of recognition and enabling the anti-counterfeiting paper pattern to play an effective anti-counterfeiting role.

[0072] Further, the organic material includes a photoinitiator, a heat-removable and / or water-washable photocurable material, and / or a UV absorber. The photoinitiator can be a pyrolytic photoinitiator, a hydrogen-abstracting photoinitiator, or a cationic photoinitiator. Pyrolytic photoinitiators can include benzoin-based photoinitiators, benzoyl-based photoinitiators, acetophenone-based photoinitiators, α-hydroxyketone-based photoinitiators, α-aminoketone-based photoinitiators, benzoylcarbamate-based photoinitiators, and acylphosphine oxide-based photoinitiators; hydrogen-abstracting photoinitiators can include benzophenone-based photoinitiators, thioxanthone-based photoinitiators, and anthraquinone-based photoinitiators; cationic photoinitiators can be thioonium salt-based photoinitiators and iodonium salt-based photoinitiators. Further, pyrolytic photoinitiators are preferred, and acylphosphine oxide-based photoinitiators are more preferred. The above-mentioned photoinitiators should be organic compounds and the amount added should not exceed 8%, more preferably not exceeding 5%. Because small amounts of specific photoinitiators can form azeotropes with easily volatile (evaporating), water- and other solvent-soluble photocurable materials, they are easy to remove. However, if unsuitable photoinitiators, such as ferrocene photoinitiators, are used, removal is difficult. Furthermore, excessive amounts of photoinitiators also hinder removal. Therefore, it is necessary to control the type and amount of photoinitiator used.

[0073] In some embodiments, optionally, the molecular weight of any component of the photocurable material does not exceed 328 g / mol.

[0074] In this embodiment, the photocurable material can be removed upon heating; therefore, it needs to possess good thermal volatility. However, boiling point does not fully reflect volatility. For example, 70-micrometer-thick layer of water at 30 degrees Celsius will evaporate even after prolonged exposure below its boiling point. Therefore, a more convenient method is needed to characterize thermal volatility. Molecular weight is a convenient way to characterize thermal volatility because substances with similar structures exhibit better volatility with lower molecular weights. Therefore, to obtain good volatility, the molecular weight of any component of the photocurable material should not exceed 328 g / mol.

[0075] In some embodiments, the photocurable material component is optionally selected from at least one compound selected from acrylate systems, methacrylate systems, acrylamide systems, N-vinyl systems, thiol-olefin systems, thiol-acetylene systems, vinyl ether systems, oxetane systems, and epoxy systems.

[0077] In some embodiments, the polymer body 120 may be formed at any location and in any shape on the substrate 110. The shape of the polymer body 120 may include at least one or a combination of Chinese characters, numbers, letters, polygons, circles, lines, QR codes, moiré patterns, moiré stripes, coded patterns, and grayscale patterns.

[0078] In this embodiment, the polymer body 120 is formed in any shape on any part of the substrate 110. The shape of the polymer body 120 can be Chinese characters, numbers, letters, rectangles, squares, circles, bars, pentagons, thin lines, patterns, numbers, QR codes, moiré patterns, moiré stripes, or other coded patterns with varying grayscale levels. By forming the polymer body 120 in any shape on any part of the substrate 110, different anti-counterfeiting patterns 1202 can be formed on the substrate 110, applicable to different anti-counterfeiting products, thus broadening the application range. Furthermore, the more complex the anti-counterfeiting pattern, the higher the anti-counterfeiting performance.

[0079] In some embodiments, the anti-counterfeiting pattern may optionally include at least one or a combination of Chinese characters, numbers, letters, polygons, circles, lines, QR codes, moiré patterns, moiré stripes, coded patterns, and grayscale patterns.

[0080] In this embodiment, the anti-counterfeiting pattern 1202 is formed on the substrate 110 in any shape, such as Chinese characters, numbers, letters, rectangles, squares or circles, bars, pentagons, thin lines, patterns, numbers, QR codes, moiré patterns, moiré stripes or other forms of coded patterns, patterns with a certain level of grayscale, etc. Because the anti-counterfeiting pattern 1202 is formed on the substrate 110 in any shape, different anti-counterfeiting patterns 1202 can be formed on the substrate 110 and applied to different anti-counterfeiting products, thus broadening the application range. Furthermore, the complexity of the pattern further enhances the anti-counterfeiting performance.

[0081] It is understood that the shape of the polymer body 120 on the substrate 110 may be the same as or different from the anti-counterfeiting pattern 1202. The anti-counterfeiting pattern 1202 may have a certain area depending on its shape.

[0082] In some embodiments, the anti-counterfeiting pattern 1202 may optionally be linear in shape, with a width greater than or equal to 50 μm and a line width precision in the range of 20 μm to 120 μm.

[0083] In this embodiment, the anti-counterfeiting pattern 1202 can be presented in a linear form, with a line width, i.e., line fineness, ranging from a minimum of less than 50 μm to a maximum of greater than 1000 μm. The line width varies depending on the pattern. Furthermore, when the anti-counterfeiting pattern is a fine line, the line width fineness must be greater than 20 μm and less than 120 μm.

[0084] In some embodiments, the anti-counterfeiting patterns 1202 may have a corresponding relationship, and a new anti-counterfeiting pattern 1202 may be formed by overprinting them.

[0085] In this embodiment, the anti-counterfeiting element 10 may contain multiple anti-counterfeiting patterns 1202, and there may be a certain correspondence between the multiple anti-counterfeiting patterns 1202. They can be superimposed on each other to generate new anti-counterfeiting patterns 1202, forming a self-check, which also facilitates users to perform anti-counterfeiting verification.

[0086] In some embodiments, the substrate 110 may be pure paper; or the middle of the substrate 110 may be a transparent plastic substrate, and the two sides of the substrate 110 may be paper; or one side of the substrate 110 may be paper, and the other side of the substrate 110 may be a plastic substrate.

[0087] In this technical solution, the substrate 110 can be pure paper, or it can be a "sandwich" paper composed of a transparent plastic substrate in the middle and paper on both sides, or it can be paper with paper on one side and a plastic substrate on the other side. Specific Implementation Example 1

[0089] Anti-counterfeiting components and products manufactured, such as Figure 1 As shown.

[0090] A photoreactive solution composed of 3,4-epoxycyclohexyl methacrylate, bis(4,4'-thioether)triphenylthionium hexafluorophosphate, and a UV-emitting material is applied to the surface of substrate 110 using a flexographic coating machine. The photoreactive solution rapidly penetrates the substrate 110. Then, as... Figure 1 The anti-counterfeiting pattern 1202 shown is exposed to a preset area using 1500nm infrared light, causing a cross-linking reaction in the photoreaction solution to form a polymer body 120. Further, a dry process is used to develop the patterned polymer, resulting in the formation of a cross-linked structure within the polymer body 120. Figure 1 The anti-counterfeiting pattern 1202 is shown. The preset area (the preset area is...) is calendered using a calendering device. Figure 1 The area within the Chinese frame is illuminated to create a transparent or semi-transparent window with a certain degree of light transmittance.

[0091] Anti-counterfeiting effect: A rectangular transparent window is formed on the anti-counterfeiting paper substrate 110, within which fine patterns with different gray levels can be observed. Under ultraviolet light, the transparent window emits fluorescent characteristics. Specific Implementation Example 2

[0093] Anti-counterfeiting components and products manufactured, such as Figure 2 As shown.

[0094] A photoreactive solution composed of TPGDA, bis(4,4'-thioether)triphenylthionium hexafluorophosphate, and an infrared luminescent material is used. The photoreactive material is coated onto the surface of the substrate 110 using a targeted spraying device. The photoreactive solution rapidly penetrates the substrate 110. Then, as... Figure 2The anti-counterfeiting pattern 1202 shown is exposed to a preset area using 1500nm infrared light, causing a cross-linking reaction in the photoreaction solution to form a polymer body 120. Further, a dry process is used to develop the patterned polymer, resulting in the formation of a cross-linked structure within the polymer body 120. Figure 2 The anti-counterfeiting pattern shown is 1202.

[0095] The preset area (the preset area is) is processed using a calendering device. Figure 2 The area containing the central circular frame is illuminated to create a window with a certain degree of transparency.

[0096] Anti-counterfeiting effect: A circular transparent window is formed on the anti-counterfeiting paper substrate 110, through which a fine pattern composed of fibers can be observed. Under infrared light, the transparent window displays infrared luminescent anti-counterfeiting features. Specific Implementation Example 3

[0098] A photoreactive solution composed of trimethylolpropane diallyl ether, thiol, isopropylthioxanthone (ITX), and an orange metal complex dye is applied to the surface of substrate 110 using a flexographic coater. The photoreactive solution rapidly penetrates the substrate 110. Then, a first preset area is exposed to 410 nm light to form a pattern, and a second preset area is exposed to 410 nm light to form a pattern composed of equally spaced rays. This causes the photoreactive solution to undergo a cross-linking reaction, forming a polymer body 120. Further, the two areas are developed using a dry process to create the patterned polymer, thereby forming an anti-counterfeiting pattern 1202 within the polymer body 120.

[0099] Anti-counterfeiting effect: Since the image in the second preset area is a pattern composed of rays with the same interval, when the substrate 110 is folded in half, due to the moiré pattern phenomenon, the preset pattern will move in the visual perception when the pattern composed of rays with the same interval is moved.

Then, a preset pattern (tiger head pattern) is exposed to 390nm light, causing the photoreactive solution to undergo a cross-linking reaction to form a polymer body 120. Further, the patterned polymer is developed using a dry process, thereby forming a structure within the polymer body 120 such as… Figure 3 The anti-counterfeiting pattern shown is 1202.

[0103] Anti-counterfeiting effect: A complete and finely transparent pattern composed of solid lines is formed on the anti-counterfeiting paper substrate 110. The line thickness of the solid lines is 50μm. Specific Implementation Example 5

[0106] A photoreactive solution composed of trimethylolpropane diallyl ether, thiol, isopropylthioxanthone (ITX), an orange metal complex dye, and an infrared luminescent material is applied to the surface of substrate 110 using a flexographic coater. The photoreactive solution rapidly penetrates the substrate 110. Then, as follows... Figure 4 The anti-counterfeiting pattern 1202 shown uses 410nm light to expose the area containing the transparent window, causing the photoreactive solution to undergo a cross-linking reaction to form a polymer body 120. Further, a dry process is used to develop the patterned polymer, resulting in the formation of a cross-linked structure within the polymer body 120. Figure 4 The anti-counterfeiting pattern 1202 is shown. Further, as shown... Figure 4 The anti-counterfeiting pattern 1202 shown uses 385 nm light to expose a region symmetrical to the preset area relative to the central axis of the substrate 110 in reverse, causing the photoreaction solution to undergo a cross-linking reaction to form a polymer body 120. Further, a dry process is used to develop the patterned polymer, thereby allowing the preset area (the preset area is...) to be developed within the polymer body 120 using a calendering device. Figure 4 The area within the Chinese frame is illuminated to create a transparent window, forming a shape resembling... Figure 4 The anti-counterfeiting pattern shown is 1202.

[0107] Anti-counterfeiting effect: A rectangular transparent window is formed on one side of the anti-counterfeiting paper substrate 110, through which a colored pattern can be observed. On the other side, a pattern with a certain degree of transparency is formed that is completely reversed from the image on the left. By folding the substrate 110, the two images can be made to completely overlap, thus ensuring that the anti-counterfeiting element passes self-inspection and improving the anti-counterfeiting performance. Specific Implementation Example 6

[0109] A photoreactive solution composed of 3,4-epoxycyclohexyl methacrylate, bis(4,4'-thioether)triphenylthionium hexafluorophosphate, and trace materials is applied to the surface of substrate 110 using a flexographic coating machine. The photoreactive solution rapidly penetrates the substrate 110. Then, a preset pattern is exposed using 365nm light through stereolithography (SLA) to cause the photoreactive solution to undergo a crosslinking reaction, forming a polymer body 120. Further, the patterned polymer is developed using a dry process, thereby forming an anti-counterfeiting pattern 1202 in the polymer body 120.

[0110] Anti-counterfeiting effect: A complete and finely detailed transparent pattern composed of solid and dashed lines is formed on the anti-counterfeiting paper substrate 110. The lines, both solid and dashed, are 50μm in diameter. The combination of solid and dashed lines enhances the anti-counterfeiting performance. Traces of material can be detected within the transparent lines, increasing the difficulty of counterfeiting. Specific Implementation Example 7

[0112] Anti-counterfeiting components and products manufactured, such as Figure 6 As shown.

[0113] A photoreactive solution composed of 3,4-epoxycyclohexyl methacrylate, bis(4,4'-thioether)triphenylthionium hexafluorophosphate, and a tracer material is applied to the surface of substrate 110 using a flexographic coating machine. The photoreactive solution rapidly penetrates the substrate 110. Then, a long rectangular pattern is created by exposing the substrate 110 around its perimeter with 410nm infrared light, causing the photoreactive solution to undergo a cross-linking reaction to form a polymer body 120. This creates a "corner watermark" around the substrate 110, providing anti-folding and anti-tear properties. Quadrilateral and pentagonal patterns are also created by exposing any position on the substrate 110 with 410nm infrared light, causing the photoreactive solution to undergo a cross-linking reaction to form the polymer body 120. The patterned polymer is then developed using a dry process, resulting in the formation of tracer materials within the polymer body 120. Figure 6 The anti-counterfeiting pattern shown is 1202.

[0114] Anti-counterfeiting effect: The anti-counterfeiting paper substrate 110 has a "corner watermark" formed around its perimeter, which can prevent folding and tearing. Alternatively, windows of any shape, such as pentagons and quadrilaterals, with a certain degree of light transmission can be made at any position of the substrate 110, which is different from windows on the market and strengthens the anti-counterfeiting effect. Specific Implementation Example 8

The photoreactive solution rapidly penetrates the substrate 110. Then, lines of different sizes are exposed to 255nm light on the substrate 110, causing the photoreactive solution to undergo a cross-linking reaction to form a polymer body 120. The line sizes include 0.1px, 0.2px, 0.3px, 0.4px, 0.5px, 0.6px, 0.7px, 0.8px, 1px, 1.5px, 2px, 2.5px, 3px, and 3.5px. The patterned polymer is developed using a dry or wet process, resulting in the formation of a pattern within the polymer body 120. Figure 7 The anti-counterfeiting pattern shown is 1202.

[0118] Anti-counterfeiting effect: Multiple stripes of varying thicknesses with light-transmitting lines are formed on the anti-counterfeiting paper substrate 110, possessing light transmission, fluorescence, and fine line patterns, thus exhibiting anti-counterfeiting capabilities. Green fluorescence is visible under ultraviolet light. Specific Implementation Example 9

[0120] Anti-counterfeiting components and products manufactured, such as Figure 8 As shown.

[0121] A photoreactive solution composed of 3,4-epoxycyclohexyl methacrylate, bis(4,4'-thioether)triphenylthionium hexafluorophosphate, and trace materials is applied to the surface of substrate 110 using a flexographic coater. The photoreactive solution rapidly penetrates the substrate 110. Then, 1500nm infrared light is used to expose the substrate 110, causing the photoreactive solution to undergo a cross-linking reaction to form a polymer body 120. In this embodiment, the polymer body 120 is directly deposited on a portion of the substrate 110, causing a change in the material of that portion of the substrate 110. After curing, a single-layer bonding is achieved.

[0122] Anti-counterfeiting effect: The material of some areas of the anti-counterfeiting paper substrate 110 is changed. Specific Implementation Example 10

[0124] The anti-counterfeiting paper patterns and anti-counterfeiting paper such as Figure 9 As shown.

[0125] First, a photoreactive material is coated onto the substrate 110. The photoreactive material contains a color-changing dye. SLA (Surface Mount Laser) is used to cure the photoreactive material while simultaneously changing the color of the dye. Then, the photoreactive material in the paper is washed away with an ethanol-water solution using an immersion washing device. The paper substrate 110 is then dried in an oven tunnel, forming a transparent window area with a colored pattern. The polymer body 120 can also form a security thread-like anti-counterfeiting pattern on the substrate 110, and set multiple different patterns within it to form various anti-counterfeiting designs. Furthermore, microtext or other elements can be hidden within the lines, further enhancing the anti-counterfeiting performance.

[0126] Anti-counterfeiting features: The bar area has a transparent colored window.

[0127] like Figure 5 As shown, an embodiment of the second aspect of the present invention provides a method for manufacturing an anti-counterfeiting element, wherein the method for manufacturing the anti-counterfeiting element includes:

[0128] S702: A photoreactive solution is obtained by mixing organic materials and anti-counterfeiting materials;

[0129] S704: Infiltrates the photoreactive solution into the target area on the substrate;

[0130] S706: Expose the target area to obtain a polymer body in the target area;

[0131] S708: The polymer body is developed to form an anti-counterfeiting pattern on the polymer body.

[0132] The method for manufacturing the anti-counterfeiting element 10 provided by the present invention first involves mixing organic materials and anti-counterfeiting materials to generate a photoreactive solution. Then, the photoreactive solution is applied or dripped onto a target area on a substrate 110, allowing it to penetrate into the interior of the target area, i.e., the gaps between paper fibers. Next, the target area is exposed to a predetermined pattern using a light source of a specific wavelength, causing the photoreactive solution to undergo a cross-linking reaction to form a polymer body 120. Finally, the pattern polymer is developed using a wet or dry process to form an anti-counterfeiting pattern 1202 on the polymer body 120.

[0133] Specifically, a photoreactive material is first placed on the target area of ​​the paper substrate 110 and allowed to penetrate into the substrate 110. Then, the organic material in the photoreactive material is processed with the paper substrate 110 to form a polymer body 120 (paper fiber-based composite material) by exposure treatment with a preset pattern. In other words, the photoreactive material undergoes a cross-linking reaction under exposure treatment to form the polymer body 120. Finally, the pattern polymer is developed using a wet or dry process to form an anti-counterfeiting element 10 with the polymer body 120.

[0134] In the anti-counterfeiting element 10 of the present invention, the polymer body 120 has a strong bond with the substrate 110 and is not easy to fall off from the substrate 110. The anti-counterfeiting ability of banknotes, securities and other security items made of security paper with this anti-counterfeiting element 10 is strong and can effectively prevent counterfeiters from copying and imitating them. The anti-counterfeiting product containing the anti-counterfeiting element 10 containing the polymer body 120 can also contain one of watermarks, security threads and other anti-counterfeiting fibers as well as combinations thereof, to further improve the anti-counterfeiting performance.

[0135] In some embodiments, the developing process may optionally include: wet developing process and / or dry developing process.

[0136] In this embodiment, the development process can be a wet development process, i.e., developing the polymer body 120 by washing with water, solvent washing, or other methods. Alternatively, the development process can be a dry development process, i.e., developing the polymer body 120 by evaporation, infrared drying, or high-temperature drying. By developing the polymer body 120, an anti-counterfeiting pattern 1202 is formed on the polymer body 120.

[0137] In some embodiments, the wavelength range of the exposure process is optionally greater than or equal to 195 nm and less than or equal to 1650 nm.

[0138] In this embodiment, the wavelength range of the exposure light source is greater than or equal to 195 nm and less than or equal to 1650 nm, that is, the wavelength range is 195 nm to 1650 nm. The exposure light source is either infrared or ultraviolet light.

[0139] Furthermore, the polymer body 120 is tested using a detection device; the detection device includes at least one or a combination of a sensor, an excitation source, an imaging device, and a transmission spectrometer.

[0140] In this embodiment, the detection device is used to detect the polymer body 120 and determine whether the anti-counterfeiting element 10 is qualified. The anti-counterfeiting element 10 can exhibit obvious anti-counterfeiting feature signals under the corresponding detection device, thereby improving the anti-counterfeiting effect and concealment effect.

[0141] The detection equipment includes: a sensor, which includes at least two of ultraviolet sensors, infrared sensors, magnetic sensors, and capacitive sensors, used to acquire anti-counterfeiting feature signals in the anti-counterfeiting element 10; an excitation source and an imaging device, used to acquire the anti-counterfeiting feature network pattern in the anti-counterfeiting element 10 and / or to acquire the optical contrast between the anti-counterfeiting medium layer and the transparent material layer in the anti-counterfeiting element 10, wherein the excitation source includes a transmission light source and / or a reflection light source, and the imaging device includes a high-resolution imaging device; and a transmission spectrometer, used to observe the anti-counterfeiting element 10.

[0142] Understandably, under a certain wavelength of light, the polymer body 120 can change color or emit light in order to detect obvious anti-counterfeiting feature signals.

[0143] The third aspect of the present invention provides an anti-counterfeiting product, comprising: an anti-counterfeiting element 10 as described in any of the technical solutions of the first aspect above.

[0144] The anti-counterfeiting product provided by the present invention includes anti-counterfeiting elements having a polymer body 120.

[0145] The anti-counterfeiting product provided by the technical solution of the present invention includes the anti-counterfeiting element 10 as described in any of the technical solutions of the first aspect of the present invention, and therefore has all the beneficial effects of the anti-counterfeiting element 10 as described in any of the technical solutions of the first aspect of the present invention, which will not be repeated here.

[0146] In some embodiments, the number of anti-counterfeiting elements may be multiple, and the multiple anti-counterfeiting elements may be stacked.

[0147] In this embodiment, when there are multiple anti-counterfeiting elements, multiple anti-counterfeiting elements can be stacked, that is, there can be a certain correspondence between the anti-counterfeiting elements, and they can be superimposed together to produce a new anti-counterfeiting element effect and form a self-test.

[0148] In some embodiments, the anti-counterfeiting product may optionally include a watermark disposed on the substrate 110; and / or a security thread disposed on the substrate 110; a transparent window disposed on the substrate 110; and / or anti-counterfeiting fibers disposed on the substrate 110; and / or anti-counterfeiting ink disposed on the substrate 110; and / or an anti-counterfeiting chip disposed on the substrate 110.
