Description

Technical Field

[0001] This application relates to the field of anti-counterfeiting technology, and in particular to a data carrier with anti-counterfeiting features. Background Technology

[0002] With the development of science and technology, various security and anti-counterfeiting documents, such as identity cards and entry / exit documents, have increasingly higher requirements for anti-counterfeiting technology, and at the same time, they also place higher demands on the efficiency of verification. Level 1 security and anti-counterfeiting elements (also known as visual authentication elements) are essential for the protection of security and anti-counterfeiting documents, and higher requirements are placed on their technical complexity, ease of processing and processing costs, verification capabilities, and anti-copying properties.

[0003] Transparent windows, appearing partially or entirely on a product, are commonly used security and anti-counterfeiting elements in documents and labels. They can integrate even more advanced security and anti-counterfeiting components. Laminated pattern technology offers advantages such as being colorless and inkless, easy to verify, environmentally friendly, and multifunctional. Combining transparent windows with laminated patterns enables an even greater range of anti-counterfeiting features.

[0004] Current similar technologies and products simply integrate laminated graphics and text onto both sides of a transparent window, making it easy for counterfeiters to forge this anti-counterfeiting feature. Therefore, there is an urgent need for a simple and reliable new type of security feature anti-counterfeiting technology. Utility Model Content

[0005] This application discloses a data carrier with anti-counterfeiting features, which can realize dynamic images that change with the viewing angle. The process is simple and the anti-counterfeiting level is high.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] This application provides a data carrier with anti-counterfeiting features, comprising a first card, a second card, and a third card connected sequentially along a common side;

[0008] The first card includes a first page, which faces the second card;

[0009] The second card includes a second page and a third page, with the second page facing the first card and the third page facing the third card; the second card includes a first transparent portion, with a first microstructure array formed on a first side of the first transparent portion, or a second microstructure array formed on a second side of the first transparent portion; wherein the first side of the first transparent portion is close to the second page, and the second side of the first transparent portion is close to the third page;

[0010] The third card includes a fourth page and a fifth page, the fourth page facing the second card and the fifth page facing away from the second card; the third card includes a second transparent portion, a third microstructure array is formed on a first side of the second transparent portion, or a fourth microstructure array is formed on a second side of the second transparent portion; wherein, the first side of the second transparent portion is close to the fourth page, and the second side of the second transparent portion is close to the fifth page;

[0011] When the second card and the third card are stacked, the orthographic projection of the first transparent part on the third card completely covers the second transparent part, and / or the orthographic projection of the second transparent part on the second card completely covers the first transparent part; one of the microstructure arrays in the first microstructure array and the second microstructure array is used to cooperate with one of the microstructure arrays in the third microstructure array and the fourth microstructure array to form a dynamic image that changes with the viewing angle from the side of the second page or from the side of the fifth page.

[0012] The aforementioned data carrier includes a first card, a second card, and a third card, which are sequentially connected along a common side, forming a flip-out structure. The first card includes a first page facing the second card; the second card includes a second page facing the first card and a third page facing the third card; the third card includes a fourth page facing the second card and a fifth page facing away from the second card. The second card includes a first transparent portion, on which a first microstructure array is formed, or on which a second microstructure array is formed, either on the first side of the first transparent portion or on the second side of the first transparent portion. Specifically, the first transparent portion forms a first microstructure array on one side of the second page, or on one side of the third page. The third card includes a second transparent portion, on which a third microstructure array is formed, or on which a fourth microstructure array is formed, either on the second side of the second transparent portion or on the fourth side of the second page. When the second and third cards are stacked, the positions of the first and second transparent parts need to correspond to each other. That is, the orthographic projection of the first transparent part on the third card completely covers the second transparent part, or the orthographic projection of the second transparent part on the second card completely covers the first transparent part. During the fabrication of the first, second, third, and fourth microstructure arrays, the first or second microstructure array integrates an image that matches the third or fourth microstructure array, so that the observer can see a dynamic image that changes with the viewing angle when viewing from the fifth page side. The third or fourth microstructure array can also integrate an image that matches the first or second microstructure array, so that the observer can also see a dynamic image that changes with the viewing angle when viewing from the second page side.

[0013] This application integrates security and anti-counterfeiting features on the first and second transparent areas. One microstructure array from the first and second microstructure arrays, in conjunction with one microstructure array from the third and fourth microstructure arrays, can form a dynamic image that changes with the viewing angle from either the second or fifth page side. By linking one side of each of the two cards together, mutual verification is achieved, creating a unique dynamic effect. This provides anti-counterfeiting functionality, is simple to manufacture, has a high anti-counterfeiting level, and is easier to verify or observe, thus enhancing the anti-counterfeiting strength of the data carrier and improving the verification efficiency of the data carrier.

[0056] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In the description of the embodiments of this application, unless otherwise stated, " / " means "or", for example, A / B can mean A or B; "and / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone.

[0057] The terms "first" and "second" are used for descriptive purposes only and should not be construed as implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0058] like Figures 1-22 As shown, this application embodiment provides a data carrier with anti-counterfeiting features, including a first card 1, a second card 2 and a third card 3 connected sequentially along a common side;

[0059] The first card 1 includes a first page 101, which faces the second card 2;

[0060] The second card 2 includes a second page 201 and a third page 202, with the second page 201 facing the first card 1 and the third page 202 facing the third card 3; the second card 2 includes a first transparent portion 21, with a first microstructure array 211 formed on a first side of the first transparent portion 21, or a second microstructure array 212 formed on a second side of the first transparent portion 21; wherein, the first side of the first transparent portion 21 is close to the second page 201, and the second side of the first transparent portion 21 is close to the third page 202;

[0061] The third card 3 includes a fourth page 301 and a fifth page 302, with the fourth page 301 facing the second card 2 and the fifth page 302 facing away from the second card 2; the third card 3 includes a second transparent portion 31, with a third microstructure array 311 formed on the first side of the second transparent portion 31, or a fourth microstructure array 312 formed on the second side of the second transparent portion 31; wherein, the first side of the second transparent portion 31 is close to the fourth page 301, and the second side of the second transparent portion 31 is close to the fifth page 302;

[0062] When the second card 2 and the third card 3 are stacked, the orthographic projection of the first transparent part 21 on the third card 3 completely covers the second transparent part 31, and / or, the orthographic projection of the second transparent part 31 on the second card 2 completely covers the first transparent part 21; one of the microstructure arrays in the first microstructure array 201 and the second microstructure array 202 is used to cooperate with one of the microstructure arrays in the third microstructure array 301 and the fourth microstructure array 302 to form a dynamic image that changes with the viewing angle from the side of the second page 201 or from the side of the fifth page 302.

[0063] like Figure 1 As shown, the data carrier includes a first card 1, a second card 2, and a third card 3. The three cards are connected one after another along a common side, forming a flip-able structure.

[0064] like Figures 2-4 As shown, the first card 1 includes a first page 101 facing the second card 2, the second card 2 includes a second page 201 facing the first card 1 and a third page 202 facing the third card 3, and the third card 3 includes a fourth page 301 facing the second card 2 and a fifth page 302 facing away from the second card 2.

[0065] Among them, continue to refer to Figures 2-4The second card 2 includes a first transparent portion 21, on which a first microstructure array 211 is formed, or on which a second microstructure array 212 is formed. That is, the first transparent portion 21 forms the first microstructure array 211 on one side of the second page 201, or the first transparent portion 21 forms the second microstructure array 212 on one side of the third page 202. The third card 3 includes a second transparent portion 31, on which a third microstructure array 311 is formed, or on which a fourth microstructure array 312 is formed on one side of the second transparent portion 31. That is, the second transparent portion 31 forms the third microstructure array 311 on one side of the fourth page 301, or the second transparent portion 31 forms the fourth microstructure array 312 on one side of the fifth page 302.

[0066] like Figure 5 As shown, when the second card 2 and the third card 3 are stacked, the positions of the first transparent part 21 and the second transparent part 31 need to correspond to each other. That is, the orthographic projection of the first transparent part 21 on the third card 3 completely covers the second transparent part 31, or the orthographic projection of the second transparent part 31 on the second card 2 completely covers the first transparent part 21.

[0067] It should be noted that during the fabrication of the first microstructure array 211, the second microstructure array 212, the third microstructure array 311, and the fourth microstructure array 312, the first microstructure array 211 or the second microstructure array 212 integrates an image that matches the third microstructure array 311 or the fourth microstructure array 312, so that when the observer observes from the side of the fifth page 302, they can see a dynamic image that changes with the viewing angle; the third microstructure array 311 or the fourth microstructure array 312 can also integrate an image that matches the first microstructure array 211 or the second microstructure array 212, so that when the observer observes from the side of the second page 201, they can also see a dynamic image that changes with the viewing angle.

[0068] This application integrates security and anti-counterfeiting features on the first transparent portion 21 and the second transparent portion 31. One microstructure array from the first microstructure array 211 and the second microstructure array 212, in conjunction with one microstructure array from the third microstructure array 311 and the fourth microstructure array 312, can form a dynamic image that changes with the viewing angle from either the second page 201 side or the fifth page 302 side. For example, as... Figure 5As shown, the two microstructure arrays are the first microstructure array 211 on the second page 201 of the second card 2 and the fourth microstructure array 312 on the fifth page 302 of the third card 3. Of course, the two microstructure arrays can also be other combinations of the microstructure arrays on the second card 2 and the third card 3. By linking one side of each of the two card bodies together, and setting the two microstructure arrays carrying security information on the transparent parts of different cards, the two sides verify each other, thereby producing a special dynamic effect. This provides anti-counterfeiting functionality, is simple in process, has a high level of anti-counterfeiting, and is easier to check or observe, enhancing the anti-counterfeiting strength of the data carrier, increasing the difficulty of counterfeiting, and improving the verification efficiency of the data carrier.

[0069] It should be noted that the first transparent portion 21 and the second transparent portion 31 can occupy a partial area of ​​the second card 2 and the third card 3, or they can occupy the entire second card 2 and the third card 3. During the fabrication process, the first microstructure array 211, the second microstructure array 212, the third microstructure array 311, and the fourth microstructure array 312 integrate security information into the array. For example, if the security information is a leaf, then the leaf information is integrated into the microstructure array of one side page of the second card 2 (or the third card 3). Accordingly, only when it is combined with the microstructure array of one side page of the third card 3 (second card 2) can the dynamic image of the leaf changing with the viewing angle be seen on the side of the second page 201 or the side of the fifth page 302.

[0070] In some embodiments, the first page 101 is provided with a first image 11, and the second card 2 and the third card 3 can be moved relative to the first card 1 so that the first transparent part 21 and the second transparent part 31 completely cover the first image 11; the first microstructure array 211 or the second microstructure array 212 is the first decoding lens 213, and the third microstructure array 311 or the fourth microstructure array 312 is the second decoding lens 313.

[0071] When the second card 2 is stacked on top of the first card 1, the first decoding lens 213 is used to reveal the first hidden information in the first image 11; or...

[0072] When the second card 2 and the third card 3 are stacked on top of the first card 1, the second decoding lens 313 is used to reveal the first hidden information in the first image 11; or...

[0073] When the second card 2 and the third card 3 are stacked on top of the first card 1, the first decoding lens 213 is used to reveal the first hidden information in the first image 11, and the second decoding lens 313 is used to reveal the second hidden information in the first image 11.

[0074] One possible way to achieve this is, such as Figure 6 As shown, combined with Figure 4 The first page 101 of the first card 1 is provided with a first image 11. When the second card 2 is stacked on top of the first card 1, the first transparent part 21 can completely cover the first image 11. When the second card 2 and the third card 3 are stacked on top of the first card 1, both the first transparent part 21 and the second transparent part 31 can completely cover the first image 11.

[0075] The hidden information in the first image 11 of this application can be decoded by the first decoding lens 213 formed by the first microstructure array 211 or the second microstructure array 212 on the second card 2; it can also be decoded by the second decoding lens 313 formed by the third microstructure array 311 or the fourth microstructure array 312 on the third card 3; or it can be decoded in two ways using the first decoding lens 213 and the second decoding lens 313 respectively. It should be noted that the first microstructure array 211 or the second microstructure array 212 of the second card 2 does not affect the decoding of the first card 1 by the second decoding lens 313 of the third card 3.

[0076] For example, when observing the first image 11 of the first card 1 alone, as Figure 7 As shown, only the five-pointed star pattern is visible. When the second card 2 is stacked on top of the first card 1, as shown... Figure 8 As shown, when viewing the first image 11 from the third page 202 side of the second card 1, the letter information hidden in the pentagram pattern of the first image 11 can be seen. This is achieved by decoding through the first decoding lens 213 on the second card 2.

[0077] Another example, continue to refer to Figure 8 When the second card 2 and the third card 3 are stacked on top of the first card 1, when the first image 11 is viewed from the fifth page 302 side of the third card 3, the letter information hidden in the pentagram pattern of the first image 11 can be seen. In this case, the decoding is performed by the second decoding lens 313 on the third card 3, and the microstructure array on the second card 2 does not affect the decoding of the second decoding lens 313.

[0078] Another example is when the second card 2 is stacked on top of the first card 1, such as Figure 8 As shown, when viewing the first image 11 from the side of the third page 202 of the second card 1, the letter information hidden in the five-pointed star pattern of the first image 11 can be seen. Based on this, when the third card 3 is stacked on top of the second card 2, as shown... Figure 9As shown, when viewing the first image 11 from the fifth page 302 side of the third card 3, the hidden numerical information in the pentagram pattern of the first image 11 can also be seen. In this case, the first decoding lens 213 and the second decoding lens 313 respectively decode the two types of hidden information in the first image 11.

[0079] This application links the first card 1, the second card 2, and the third card 3 together, and can achieve the decoding function of the hidden information of the first image 11 by using only the second card 2, or only the third card 3, or by using both the second card 2 and the third card 3 at the same time, thereby further improving the anti-counterfeiting strength and verification efficiency of the data carrier.

[0080] In some embodiments, when the second card 2 and the third card 3 are stacked on top of the first card 1, the area of ​​the second page 201 or the third page 202 covered by the first decoding lens 213 is parallel to the area of ​​the first page 101 covered by the first image 11; the area of ​​the fourth page 301 or the fifth page 302 covered by the second decoding lens 313 is parallel to the area of ​​the first page 101 covered by the first image 11.

[0081] One possible way to achieve this is, such as Figure 10 As shown, when the second card 2 and the third card 3 are stacked on top of the first card 1, the area of ​​the second page 201 covered by the first decoding lens 213 of the second card 2 is parallel to the area of ​​the first page 101 covered by the first image 11. The area of ​​the fifth page 302 covered by the second decoding lens 313 of the third card 3 is parallel to the area of ​​the first page 101 covered by the first image 11. It should be noted that, within the allowable error range and provided that the decoding effect can be achieved, there can be a maximum angle of 10° between the first decoding lens 213 (or the second decoding lens 313) and the first image 31.

[0082] In some embodiments, the second card 2 further includes a first non-decoding area 214, and the third card 3 includes a second non-decoding area 314;

[0083] The area of ​​the second page 201 or the third page 202 covered by the first decoding lens 213 is parallel to the area of ​​the second page 201 or the third page 202 covered by the first non-decoding area 214, and the area of ​​the fourth page 301 or the fifth page 302 covered by the second decoding lens 313 is parallel to the area of ​​the fourth page 301 or the fifth page 302 covered by the second non-decoding area 314.

[0084] Alternatively, the area of ​​the second page 201 or the third page 202 covered by the first decoding lens 213 is parallel to the area of ​​the second page 201 or the third page 202 covered by the first non-decoding area 214, and the area of ​​the fourth page 301 or the fifth page 302 covered by the second decoding lens 313 is not parallel to the area of ​​the fourth page 301 or the fifth page 302 covered by the second non-decoding area 314.

[0085] Alternatively, the area of ​​the second page 201 or the third page 202 covered by the first decoding lens 213 is not parallel to the area of ​​the second page 201 or the third page 202 covered by the first non-decoding area 214, and the area of ​​the fourth page 301 or the fifth page 302 covered by the second decoding lens 313 is parallel to the area of ​​the fourth page 301 or the fifth page 302 covered by the second non-decoding area 314.

[0086] Alternatively, the area of ​​the second page 201 or the third page 202 covered by the first decoding lens 213 is not parallel to the area of ​​the second page 201 or the third page 202 covered by the first non-decoding area 214, and the area of ​​the fourth page 301 or the fifth page 302 covered by the second decoding lens 313 is not parallel to the area of ​​the fourth page 301 or the fifth page 302 covered by the second non-decoding area 314.

[0087] One possible way to achieve this is, such as Figure 11 and Figure 12 As shown, the first decoding lens 213 and the first non-decoding area 214 are parallel, and the second decoding lens 313 and the second non-decoding area 314 are parallel. Specifically, as... Figure 13 As shown, the first decoding lens 213 and the first non-decoding area 214 are in the same plane, and the second decoding lens 313 and the second non-decoding area 314 are in the same plane. Of course, the first decoding lens 213 and the first non-decoding area 214 can also be parallel, and the second decoding lens 313 and the second non-decoding area 314 can be in the same plane, etc. The specific arrangement is not limited.

[0088] Another possible way to achieve this is, such as Figure 14 As shown, the first decoding lens 213 and the first non-decoding area 214 are in the same plane, and the second decoding lens 313 and the second non-decoding area 314 are at an angle.

[0089] Another possible way to achieve this is, such as Figure 15 As shown, the first decoding lens 213 and the first non-decoding area 214 are at an angle, and the second decoding lens 313 and the second non-decoding area 314 are in the same plane.

[0090] Another possible way to achieve this is, such as Figure 16As shown, the first decoding lens 213 and the first non-decoding area 214 are at an angle, and the second decoding lens 313 and the second non-decoding area 314 are also at an angle.

[0091] In practical applications, the orientations of the first decoding lens 213, the first non-decoding area 214, the second decoding lens 313, and the second non-decoding area 314 can be set according to the desired effect. That is to say, different areas of the same card can be at angles and are not necessarily completely flat; different cards can be parallel or not completely parallel, without any specific limitation.

[0092] In some embodiments, the included angle α between the area of ​​the second page 201 or the third page 202 covered by the first non-decoding area 214 and the area of ​​the fourth page 301 or the fifth page 302 covered by the second non-decoding area 314 is 0°-90°.

[0093] One possible way to achieve this is, such as Figures 11-16 As shown, the included angle α between the first non-decoding area 214 and the second non-decoding area 314 is 0°-90°, such as 0°, 2°, 5°, 8°, 10°, 15°, 20°, 25°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, etc., and the specific angle is not limited.

[0094] In some embodiments, the second card 2 further includes a third transparent portion 22, a fifth microstructure array 221 is formed on a first side of the third transparent portion 22, and a sixth microstructure array 222 is formed on a second side of the third transparent portion 22; wherein, the first side of the third transparent portion 22 is close to the second page 201, and the second side of the third transparent portion 22 is close to the third page 202; the fifth microstructure array 221 is used to cooperate with the sixth microstructure array 222 to form a dynamic image that changes with the viewing angle from the side of the second page 201 or from the side of the third page 202.

[0095] One possible way to achieve this is, such as Figure 17 and Figure 18As shown, the second card 2 also includes a third transparent portion 22. A fifth microstructure array 221 is formed on the first side of the third transparent portion 22, and a sixth microstructure array 222 is formed on the second side of the third transparent portion 22. That is, the third transparent portion 22 forms the fifth microstructure array 221 on one side of the second page 201, and the third transparent portion 22 forms the sixth microstructure array 222 on one side of the third page 202. Similarly, during the fabrication of the fifth microstructure array 221 and the sixth microstructure array 222, an image matching the sixth microstructure array 222 (or the fifth microstructure array 221) is integrated inside the fifth microstructure array 221 (or the sixth microstructure array 222), so that when the observer views from the second page 201 side or from the third page 202 side, a dynamic image that changes with the viewing angle can be seen.

[0096] This application also uses two microstructure arrays with security information set on the transparent part of the same card. The two sides of the card verify each other, thereby producing a special dynamic effect, which has the function of anti-counterfeiting. The process is simple, the anti-counterfeiting level is high, and it is easier to check or observe, which enhances the anti-counterfeiting strength of the data carrier, increases the difficulty of counterfeiting, and improves the verification efficiency of the data carrier.

[0097] It should be noted that when using the same card for verification, in specific applications, the third card (3) can also be set to be entirely opaque; or the third card (3) can be set to be partially transparent and partially opaque, such as... Figure 17 and Figure 18 As shown, the second transparent portion 31 of the third card 3 can cooperate with the first transparent portion 21 of the second card 2 for verification, and the opaque portion of the third card 3 is decoded by the third transparent portion 22 of the second card 2. The specific third card 3 can be set according to the actual situation, and is not limited here.

[0098] In some embodiments, the first page 101 is provided with the second image 12, the fourth page 301 is provided with the third image 32, the second card 2 can be moved relative to the first card 1 and the third card 3 so that the third transparent part 22 completely covers the second image 12 and the third image 32; the fifth microstructure array 221 is the third decoding lens 223, and the sixth microstructure array 222 is the fourth decoding lens 224.

[0099] When the second card 2 is stacked on top of the first card 1, the fourth decoding lens 224 is used to make the third hidden information in the second image 12 visible; or, the fourth decoding lens 224 and the third decoding lens 223 are used to make the third hidden information and the fourth hidden information in the second image visible.

[0100] When the second card 2 is stacked on top of the third card 3, the third decoding lens 223 is used to reveal the fifth hidden information in the third image 32; or, the third decoding lens 223 and the fourth decoding lens 224 are used to reveal the fifth and sixth hidden information in the second image 32.

[0101] In one possible implementation, refer to Figure 17 and Figure 18 When the second card 2 is stacked on top of the first card 1, the third transparent part 22 can completely cover the second image 12. When the second card 2 is stacked on top of the third card 3, the third transparent part 22 can completely cover the third image 32.

[0102] The hidden information in the second image 12 and the third image 32 of this application can be decoded by one of the third decoding lens 223 and the fourth decoding lens 224, or by both the third decoding lens 223 and the fourth decoding lens 224 respectively. It should be noted that when the third decoding lens 223 (or the fourth decoding lens 224) performs decoding, the fourth decoding lens 224 (or the third decoding lens 223) will not have any effect.

[0103] For example, when observing the second image 12 of the first card 1 alone, refer to Figure 7 Only the five-pointed star pattern is visible. When the second card 2 is stacked on top of the first card 1, as... Figure 8 As shown, when viewing the second image 12 from the third page 202 side of the second card 1, the letter information hidden in the pentagram pattern of the second image 12 can be seen. This is achieved through decoding using the fourth decoding lens 224 on the second card 2. Figure 9 As shown, when viewing the second image 12 from the third page 202 side of the second card 1, the letter and number information hidden in the pentagram pattern of the second image 12 can be seen. In this case, the third decoding lens 223 and the fourth decoding lens 224 decode the two types of hidden information in the second image 12 respectively. Similarly, the decoding principle of the hidden information in the third image 32 on the third card 3 is similar to that of the second image 12, and will not be described again here.

[0104] This application also allows the microstructure array with dynamic effects and decoding functions to be set only on the second card 2. This also achieves the card's anti-counterfeiting function, providing a high level of anti-counterfeiting and enhancing the anti-counterfeiting strength of the data carrier, thus increasing the difficulty of counterfeiting.

[0105] In some embodiments, the fabrication process of the microstructure array of this application includes at least one of lamination, printing, and hot stamping. Printing includes at least one of offset printing, screen printing, gravure printing, and lithography, and the printing ink includes optically variable ink.

[0106] The microstructure arrays of this application (including the first microstructure array 211, the second microstructure array 212, the third microstructure array 311, the fourth microstructure array 312, the fifth microstructure array 221, and the sixth microstructure array 222) can be prepared by direct processing, such as printing and hot stamping. The printing process can include offset printing, screen printing, gravure printing, and lithography, and the ink used can be photochromic ink. By adopting direct processing, the precision of the microstructure array can be improved, further enhancing the anti-counterfeiting capabilities of the data carrier. Simultaneously, the use of photochromic ink can also achieve color effects for dynamic images. Furthermore, direct processing also includes physical processes (machining) and chemical processes (laser engraving, wet etching), etc.

[0107] Of course, microstructure arrays can also be fabricated indirectly, namely through lamination. First, the microstructure array is fabricated on a laminate, and then the laminate with the microstructure array is transferred onto the data carrier card. The substrate of the transfer material (i.e., the laminate) can be a smooth metal sheet such as stainless steel, nickel, or cadmium, or a smooth polymer sheet such as PET or polytetrafluoroethylene. The thickness of the laminate is not limited, but it is usually a smooth sheet with a thickness of 0.8 mm or more. The fabrication processes for the microstructure array on the laminate include physical processes (machining, dry physical etching) and chemical processes (dry chemical etching, wet etching, wet corrosion, laser engraving, electroplating growth, PVD growth, ALD growth, auxiliary processes of the above processes, and combined processes). The lamination method for transferring the microstructure array onto the data carrier card can include thermal transfer.

[0108] The data carrier card in this application can be a transparent or partially transparent polymer card or sheet, made of materials including PC, PVC, PET, PTEG, etc., with PC material being the most common choice. PC material must also be used when laser engraving is required to load anti-counterfeiting information. The card thickness can be set according to the requirements of different types of products.

[0109] In some embodiments, the processing technology for hiding information includes at least one of laser printing, laser engraving, laser lithography, inkjet printing, offset printing, gravure printing, letterpress printing, and screen printing.

[0110] The hidden information in this application can only be revealed using a decoding lens formed by the first microstructure array 211, the second microstructure array 212, the third microstructure array 311, the fourth microstructure array 312, the fifth microstructure array 221, and the sixth microstructure array 222. The hidden information can be colored, colorless fluorescent, or colored fluorescent, or combinations thereof, wherein the fluorescence includes fluorescence in various bands such as ultraviolet excitation fluorescence, green light excitation fluorescence, and infrared excitation fluorescence.

[0111] In some embodiments, the second card 2 and the third card 3 further include laser marking information 41, which is configured to work with the microstructure array to produce different transient images at different viewing angles.

[0112] One possible way to achieve this is, such as Figure 19 As shown, both the second card 2 and the third card 3 include laser marking information 41, which contains transient images that can present different information at different viewing angles. For example, as Figures 20-22 As shown, when an observer views the laser marking information 41 of the second card 2 and the third card 3 through the second page 201 and the fifth page 302, from the first viewing angle, one can see as follows: Figure 20 The information shown; from the second viewing angle, one can see as follows: Figure 21 The information shown; from the third viewing angle, one can see as follows: Figure 22 The information shown is as described above. Of course, the laser marking information 41 can also be designed as an animation effect that changes continuously with different viewing angles. This animation effect is different from the aforementioned dynamic effect. The animation effect here can be selectively and individually customized so that different information is loaded into the laser marking information 41.

[0113] The laser marking information 41 in this application can be one or more colored, colorless fluorescent, or colored fluorescent information, or combinations thereof. When the card material is a laser-engravable laser-sensitive material, the laser marking information 41 can also be loaded by laser engraving or other methods. The laser marking information 41, associated with the microstructure array, can generate different transient images. When loading the laser marking information 41, the card is rotated in the same direction (clockwise or counterclockwise). Personalized information is loaded at each position after a certain rotation angle, and this process is repeated two or more times to finally obtain the laser marking information 41. The personalized information at different angles can be the same or different, and can overlap or not overlap.

[0114] It should be noted that the data carrier of this application can be any security and anti-counterfeiting document, including banknotes, identity documents, entry and exit documents, anti-counterfeiting packaging, anti-counterfeiting labels, and other documents in the security field. The anti-counterfeiting features of this application can also be combined or superimposed with other anti-counterfeiting technologies and components, including laminated anti-counterfeiting graphics, irregularly shaped transparent windows, special anti-counterfeiting inks, special color-changing films, metallic mesh, laser perforation, etc., to further increase the difficulty of counterfeiting, forging, and replacing the data carrier, and improve the anti-counterfeiting performance of the product.

[0115] The following description is made for the first microstructure array 111, the second microstructure array 112, the third microstructure array 211, the fourth microstructure array 212, the fifth microstructure array 221, and the sixth microstructure array 222.

[0116] In the microstructure array, each region's microstructure can be a prism element of the same height, with the same cross-sectional shape perpendicular to the card thickness direction, such as a square, rectangle, parallelogram, ellipse, triangle, or similar shape. The lengths of the microstructures can be equal or unequal. Each microstructure has at least two facets, typically a cylindrical structure with numerous optical faces, and each microstructure can be continuous or discontinuous along its length. The dimensions of each microstructure need to be at least 30 μm (length) × 30 μm (width), preferably at least 100 μm wide, and preferably at least 200 μm long.

[0117] The microstructure may or may not protrude from the card surface. The lengths of the microstructures in the first and second cards must be at least partially consistent or nearly consistent. Along the length of the microstructure, it can be straight or curved, and the waveform formed by the curvature can be regular or irregular. Accordingly, the design of the hidden information in the first and second images needs to be matched accordingly.

[0118] The first microstructure array 111, the second microstructure array 112, the third microstructure array 211, the fourth microstructure array 212, the fifth microstructure array 221, and the sixth microstructure array 222 can generate at least one dynamic image, each image having optical properties that change with the viewing angle. Each dynamic image corresponds to a three-dimensional microstructure group, and each three-dimensional microstructure group consists of microstructures with equivalent or identical displacement x. In a given space, each three-dimensional microstructure group corresponds to a viewing angle. When multiple dynamic images are arranged at intervals, a dynamic effect can be presented as the viewing angle changes. The direction of movement of the dynamic image can be controlled by the arrangement of each three-dimensional microstructure group.

[0119] When the first microstructure array 111, the second microstructure array 112, the third microstructure array 211, the fourth microstructure array 212, the fifth microstructure array 221, and the sixth microstructure array 222 can generate multiple dynamic images, each image can be associated or not associated. When images are associated, there can be continuous or discontinuous animation effects. Continuous animation includes scaling effects, translation effects, rotation effects, gradation effects, and similar dynamic effects, or combinations of multiple effects. Translation animation effects can be straight lines, curves (regular or irregular waveform changes), or broken lines (zigzag patterns or other irregular changes).

[0120] The speed of animation changes can be controlled by the microstructure arrangement design of the 3D microstructure group. Generally, the smaller the change in displacement x between two adjacent 3D microstructure groups, the easier it is to control the coherence and continuity of the animation effect. The animation effect needs to be observed by rotating the card. The animation effect can be observed on both the front and back of the card. The rotation angle can be any angle that the human eye can observe, and the angle can be controlled by the microstructure arrangement design of the 3D microstructure group.

[0121] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
