[0002] Data carriers such as valuable documents (banknotes, passports, ticket tags, etc.), identification documents (credit cards, ID cards, etc.) and other valuable items (brand-name goods) are usually equipped with tactile and optical patterns. These patterns are distributed in different areas of the data carrier to verify its authenticity and to protect it from unauthorized copying.

[0003] Existing methods use printing processes to overprint tactile and optical patterns onto a carrier to create a combination of multiple anti-counterfeiting technologies, thereby enhancing the anti-counterfeiting capabilities of the data carrier. However, due to limitations in equipment and processes, it is impossible to achieve high-precision overprinting of tactile and optical patterns, making it difficult to realize features such as precise alignment and nesting of tactile and optical patterns, thus affecting the anti-counterfeiting capabilities of the data carrier. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is that, due to the limitations of equipment and processes in the prior art, it is impossible to achieve high-precision registration of tactile patterns and optical patterns, thus making it difficult to realize the precise wiring and precise nesting of tactile patterns and optical patterns, thereby affecting the anti-counterfeiting capability of the data carrier.

[0005] Therefore, the present invention provides an anti-counterfeiting element, comprising:

[0006] The carrier has a first surface;

[0007] The first pattern is located on the first surface, and its maximum height on the first surface is A, where 20um≤A≤200um;

[0011] Optionally, in the above-mentioned anti-counterfeiting element, the second pattern has a first optical effect, and / or the first pattern has a second optical effect.

[0012] Optionally, in the above-mentioned anti-counterfeiting element, the second pattern is based on the maximum height C of the first surface, where 0.1um ≤ C ≤ 20um.

[0013] Optionally, the second pattern of the aforementioned anti-counterfeiting element includes one or more of the following: grating structure, embossed structure, micromirror structure, microlens structure, hollow structure, recessed structure, and raised structure.

[0014] Optionally, the anti-counterfeiting element described above further includes a metal layer, which covers the surface of the second pattern facing away from the carrier, and / or the metal layer covers the surface of the first pattern facing away from the carrier.

[0015] Optionally, the anti-counterfeiting element described above further includes a first medium layer, which covers the side of the second pattern that is away from the carrier, and / or the first medium layer covers the side of the first pattern that is away from the carrier.

[0016] Optionally, the anti-counterfeiting element described above also includes a second medium layer, which covers the side of the metal layer facing away from the carrier.

[0017] Optionally, in the above-mentioned anti-counterfeiting element, the ink layer is located on the first surface, and the two sides of the ink layer are respectively connected to two adjacent patterns.

[0018] The present invention also provides an anti-counterfeiting product, including the anti-counterfeiting elements described above.

[0019] The technical solution provided by this invention has the following advantages:

[0020] 1. The anti-counterfeiting element provided by the present invention includes a carrier, at least one first pattern, and at least one second pattern. The carrier has a first surface; the first pattern is located on the first surface, and the maximum height of the first surface is A, where 20um ≤ A ≤ 200um; the second pattern is located on the first surface, and the registration error between the first pattern and the second pattern is B, where B ≤ ±10um. The registration error between the first pattern and the second pattern is less than or equal to 10um, which satisfies the high-precision registration of the first pattern and the second pattern on the data carrier, thereby breaking through the limitation of the regional design of the first pattern and the second pattern. This allows for high-precision registration combinations such as the first pattern and the second pattern being connected, precisely interlaced, and overlapping, thus improving the anti-counterfeiting capability and artistic effect of the data carrier.

[0038] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] Example 1

[0040] The anti-counterfeiting components provided in this embodiment, such as Figures 1 to 7 As shown, it includes a carrier 1, at least one first pattern 2, and at least one second pattern 3. The carrier 1 has a first surface; the first pattern 2 is located on the first surface, and the maximum height based on the first surface is A, where 20um≤A≤200um; the second pattern 3 is located on the first surface, and the registration error value of the first pattern 2 and the second pattern 3 is B, where B≤±10um.

[0041] Specifically, carrier 1 can be a data carrier 1 for banknotes, credit cards, securities, and other high value-added products. The material of carrier 1 can be any of plastic, paper, or metal. The first pattern 2 and the second pattern 3 are markings on the data carrier 1. For example, the paper body of the banknote is the data carrier 1, the face value number of the banknote can be the first pattern 2, and the anti-counterfeiting pattern on the banknote can be the second pattern 3. The first pattern 2 and the second pattern 3 are printed on the first surface of carrier 1 by ultraviolet embossing, thermoplastic embossing, electron beam curing embossing, or other printing methods. Before printing, it is necessary to prepare a printing master for printing the first pattern 2 and the second pattern 3. The printing master includes a body, a first printing structure, and a second printing structure. The first and second printing structures are distributed on one side surface of the body, and the registration error between the first and second printing structures is less than or equal to 10 μm. The first printing structure is used to form a first pattern 2 during printing, and the second printing structure is used to form a second pattern 3 during printing. The printing master is manufactured as follows: a photoresist layer is coated on one side surface of the body. The photoresist layer has a first region and a second region. The first printing structure is formed in the first region of the photoresist layer by photolithography. Then, the photoresist layer in the non-second region is exposed and cured by deep ultraviolet light or electron beam. Then, the second printing structure is formed in the second region of the photoresist layer by positioning and photolithography. Finally, the excess photoresist layer is removed to complete the production of the master. In an alternative embodiment, the printing master is fabricated as follows: a first substrate structure is formed on one side surface of the body using ultraviolet embossing, thermoplastic embossing, or electron beam embossing. Then, a photoresist layer is coated onto the surface of the body with the first substrate structure. A second substrate structure is formed within the photoresist layer using a positioning process and photolithography. Finally, excess photoresist is removed to complete the master fabrication. The positioning process for fabricating the printing master utilizes micro-nano fabrication photolithography exposure equipment, achieving a positioning accuracy of 10µm or less. The first surface can be different sides of the carrier 1. The first pattern 2 can be a tactile structure, or it can be a tactile structure superimposed with an optical microstructure. The second pattern 3 can be a non-tactile optical microstructure, which can produce optical effects. Of course, the second pattern 3 can also be other anti-counterfeiting patterns. The maximum height of the first pattern 2 based on the first surface is A, where height refers to the height perpendicular to the first surface, and 20um ≤ A ≤ 200um. Preferably, the first pattern 2 is used to achieve a clear tactile feel. When the maximum height of the first pattern 2 is less than 20um, a clear tactile feel cannot be produced. When the maximum height of the first pattern 2 is greater than 200um, the first pattern 2 is difficult to process and form. The registration error value is the deviation of the geometric position of the outlines of the first pattern 2 and the second pattern 3 on the data carrier 1. By reducing the registration error value of the first pattern 2 and the second pattern 3 to below 10um, high-precision registration of the first pattern 2 and the second pattern 3 is ensured.

[0042] The anti-counterfeiting element provided in this embodiment has a registration error of less than or equal to 2µm for the first pattern 2 and the second pattern 3, which satisfies the high-precision registration of the first pattern 2 and the second pattern 3 on the data carrier 1. This breaks through the limitation of the regional design of the first pattern 2 and the second pattern 3, and can achieve high-precision registration combination effects such as the first pattern 2 and the second pattern 3 being connected, accurately interlaced, and overlapping, thereby improving the anti-counterfeiting capability and artistic effect of the data carrier 1.

[0043] The anti-counterfeiting components provided in this embodiment, such as Figure 1 As shown, the number of the first pattern 2 and the second pattern 3 can be adjusted as needed. Since the registration error of the first pattern 2 and the second pattern 3 is less than or equal to 10um, the first pattern 2 and the second pattern 3 can be spliced ​​together to form a set pattern. As a first alternative implementation, the first pattern 2 and the second pattern 3 can also be interspersed. As a second alternative implementation, the first pattern 2 and the second pattern 3 can partially overlap or coincide. As a third alternative implementation, the first pattern 2 and the second pattern 3 can be spaced apart. Of course, the first pattern 2 and the second pattern 3 can also have other positional relationships.

[0044] The anti-counterfeiting components provided in this embodiment, such as Figures 2 to 7 As shown, the second pattern 3 has a microstructure that uses one or more optical properties such as diffraction, reflection, refraction, and scattering to form a first optical effect. The microstructure includes one or more of the following: grating, relief structure, micromirror, microlens, hollow structure, recessed structure, and raised structure. The first pattern 2 is superimposed with a microstructure that uses one or more optical properties such as diffraction, reflection, refraction, and scattering to form a second optical effect. Of course, the first pattern 2 may not be superimposed with a microstructure and may only have a tactile structure.

[0045] In the anti-counterfeiting element provided in this embodiment, the maximum height of the first surface of the second pattern 3 is C, where 0.1um≤C≤20um, and the height is the height perpendicular to the first surface. When the height of the second pattern 3 is less than 0.1um, the second pattern 3 cannot be stably connected to the carrier layer 1. When the height of the second pattern 3 is greater than 20um, the manufacturing cost of the second pattern 3 increases.

[0046] The anti-counterfeiting element provided in this embodiment also includes a metal layer 4. The material of the metal layer 4 can be aluminum, copper, silver, tin or other metals or alloys. Since aluminum is inexpensive and has high brightness, it is preferred. The metal layer 4 can be formed on the surface of the second pattern 3 by vapor deposition process, or it can be formed on the surface of the first pattern 2. The vapor deposition process includes, but is not limited to, thermal evaporation, magnetron sputtering, etc. The metal layer 4 can play a reflective role.

[0047] The anti-counterfeiting element provided in this embodiment also includes a first dielectric layer, which may be made of transparent resin or other transparent materials. The first dielectric layer is used to protect the structure below it. The first dielectric layer is formed on the surface of the first pattern 2 by printing or coating process, or it may be formed on the surface of the second pattern 3. In an alternative embodiment, a second dielectric layer is also included. The second dielectric layer may be made of transparent resin or other transparent materials. The second dielectric layer may be formed on the surface of the metal layer 4 by printing or coating process.

[0048] The anti-counterfeiting element provided in this embodiment also includes an ink layer 5, which is located on the first surface. The ink layer 5 is used to connect two adjacent pattern layers that are spaced apart, and the ink layer 5, the first pattern layer 2, and the second pattern layer 3 are used to form a pattern with more artistic effects.

[0049] like Figure 2 As shown, in a first alternative implementation, the first pattern 2 is a tactile structure with a U-shaped cross-sectional shape. The second pattern 3 is a grating structure 31, and a metal layer 4 covers the second pattern 3. Different color effects can be observed in the second pattern 3 through reflection. The metal layer 4 enhances the reflective effect; the metal layer 4 is an aluminum layer. Figure 3 As shown, as a second alternative implementation, the first pattern 2 is a tactile structure with a V-shaped cross-sectional shape. The second pattern 3 has a micro-reflective mirror structure 32, which can achieve a dynamic effect, i.e., the second pattern 3 has light and dark areas. By tilting the carrier 1, the changes in the light and dark areas can be observed. The metal layer 4 covers the second pattern 3. Figure 4 As shown, as a third alternative implementation, the first pattern 2 includes a tactile structure with wavy lines, and the second pattern 3 is a microlens array 33, which can achieve dynamic display effects. Figure 5 As shown, as a fourth alternative implementation, the first pattern 2 is a tactile structure, and the cross-sectional shape of the lines of the tactile structure can be hill-shaped. The second pattern 3 includes a grating structure 31 and a micromirror structure 32, which are connected. Figure 6 As shown, as a fifth alternative implementation, the first pattern 2 is a tactile pattern structure, with an ink layer 5 between two adjacent tactile structure lines. The ink layer 5 is located on the carrier 1 and can be printed or coated onto the carrier 1. The ink layer 5 is used to connect the lines of the two tactile structures. The second pattern 3 is a grating structure 31, and another ink layer 5 is used to connect adjacent tactile structures and the grating structure 31. Figure 7As shown, as a sixth alternative implementation, the first pattern 2 includes a tactile structure and a microstructure superimposed thereon, so that a second optical effect can appear on the first pattern 2. Specifically, a grating structure can be superimposed on the tactile structure. Of course, other microstructures can also be superimposed. The second pattern 3 is also a grating structure, and the lines of the first pattern 2 and the second pattern 3 are connected.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
