Description

Technical Field

[0001] This invention relates to the field of anti-counterfeiting technology, specifically to an anti-counterfeiting element and an anti-counterfeiting product having the same. Background Technology

[0002] To enhance the anti-copying and anti-counterfeiting properties of high-security printed materials such as banknotes and certificates, anti-counterfeiting technologies such as metal removal, magnetism, and ultraviolet fluorescence are widely used. These technologies are often embedded in the form of security threads, which not only improve the anti-counterfeiting effect of the products but also allow machines to read them, enabling authentication and sorting.

[0003] Among demetallization, magnetism, and fluorescence features, the combined application of magnetism and fluorescence is relatively common. Typically, magnetic text is printed on a fluorescent background, and the magnetic text is visible on both sides under transmitted light, while under ultraviolet light, a full-page fluorescent feature is visible on the fluorescent side. The combined application of magnetism and fluorescence further enhances anti-counterfeiting measures and improves ease of identification.

[0004] However, the above scheme is just a simple superposition of coating structures. The anti-counterfeiting features generated by each coating do not interfere with each other, resulting in insufficient innovation in anti-counterfeiting features and low anti-counterfeiting performance. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the anti-counterfeiting features generated by each coating of the multi-layer anti-counterfeiting element do not interfere with each other and the anti-counterfeiting performance is low in the prior art, thereby providing an anti-counterfeiting element and an anti-counterfeiting product having it.

[0006] To address the aforementioned technical problems, this invention provides an anti-counterfeiting element, comprising:

[0007] Substrate;

[0008] A metal layer is disposed on the substrate, the metal layer having a marking area having a hollow pattern;

[0009] A fluorescent layer covers the marking area of ​​the metal layer;

[0010] A magnetic layer is disposed alongside the fluorescent layer, and the metal layer has an exposed area for exposing the magnetic layer.

[0011] Optionally, the magnetic layer has patterned markings.

[0012] Optionally, the exposed area of ​​the metal layer is a whole hollow area, or the exposed area of ​​the metal layer is a partially hollow area, and the pattern formed by the partially hollow area is consistent with the pattern mark on the magnetic layer.

[0013] Optionally, a covering layer is provided on the side of the magnetic layer away from the metal layer, and the covering layer completely covers the magnetic layer.

[0014] Optionally, the covering layer is an ink coating with a covering effect.

[0015] Optionally, the magnetic layer is made of a magnetically conductive material.

[0016] Optionally, the magnetic layer is made of a hard magnetic material or a soft magnetic material.

[0017] Optionally, a protective layer is further included, disposed between the metal layer and the fluorescent layer, the protective layer having a perforated pattern that matches the shape of the perforated pattern on the marking area of ​​the metal layer.

[0018] Optionally, the system includes a first functional layer and a second functional layer arranged in parallel and spaced apart, with the substrate, metal layer, and fluorescent layer disposed between the first functional layer and the second functional layer.

[0019] The present invention provides an anti-counterfeiting product, comprising the anti-counterfeiting element described in any of the above-described solutions.

[0020] The technical solution of this invention has the following advantages:

[0021] 1. The anti-counterfeiting element provided by this invention, under white light transmission conditions, allows for the observation of a translucent perforated pattern from both sides. The magnetic layer is typically made of colored magnetic ink, and the colored magnetic layer is visible from both sides. Under ultraviolet light conditions, only the entire fluorescent color block is visible on the fluorescent layer side, while a fluorescent perforated pattern is visible on the metal layer side. The magnetic layer can be detected by a magnetic sensor to obtain a magnetic coding sequence. By detecting the magnetic layer with a magnetic sensor, the pulse fluctuations of magnetic flux on the magnetic layer can be identified, forming a magnetic coding sequence, providing magnetic anti-counterfeiting features, and increasing the diversity of anti-counterfeiting features. Through the cooperation of various coatings, different anti-counterfeiting features are produced, thereby improving the anti-counterfeiting performance. The anti-counterfeiting element provided by this invention solves the problem in the prior art where the anti-counterfeiting features produced by each coating of a multi-layer anti-counterfeiting element do not interfere with each other, resulting in low anti-counterfeiting performance.

[0022] 2. The anti-counterfeiting element provided by the present invention has a pattern mark set on the magnetic layer. The magnetic layer is usually made of colored magnetic ink. The exposed area on the metal layer can expose the colored mark of the magnetic layer. Under white light transmission conditions, the colored mark formed by the pattern mark on the magnetic layer can be seen from both sides, which increases the diversity of anti-counterfeiting features and improves anti-counterfeiting performance.

[0023] 3. The anti-counterfeiting element provided by the present invention can have its exposed metal layer area set as a whole or partially hollowed out. With this setting, the colored mark on the magnetic layer can be seen from both sides of the anti-counterfeiting element, increasing the diversity of anti-counterfeiting features and improving anti-counterfeiting performance.

[0024] 4. The anti-counterfeiting element provided by the present invention protects and blocks one side of the magnetic layer with a covering layer, improving aesthetics. Moreover, it makes the shape features of the magnetic layer invisible when viewed from the covering layer side, while the colored marks formed by the magnetic layer can be seen when viewed from the magnetic layer side, increasing the diversity of anti-counterfeiting features and improving anti-counterfeiting performance.

[0025] 5. The anti-counterfeiting element provided by the present invention uses an ink coating with a covering effect as a covering layer, which can cover the colored magnetic layer and improve the aesthetics of the element.

[0026] 6. The anti-counterfeiting element provided by the present invention uses a magnetic conductive material to make a magnetic layer, which can provide both magnetic and conductive codes. When superimposed with the conductive code of the metal layer, a new conductive code sequence can be generated, thereby improving the anti-counterfeiting performance.

[0027] 7. The anti-counterfeiting element provided by the present invention uses a magnetic layer made of hard magnetic material or soft magnetic material, which can generate different magnetic coding sequences according to the characteristics of the material; hard magnetic material is difficult to demagnetize after magnetization and has high residual magnetic induction intensity. It is usually magnetized by an excitation device first and then detected by a magnetic sensor, which can be used in conventional anti-counterfeiting devices; soft magnetic material is easy to demagnetize after magnetization and needs to be magnetized and detected at the same time, which is not suitable for conventional anti-counterfeiting devices.

[0028] 8. The anti-counterfeiting element provided by the present invention protects the metal layer with a protective layer to prevent oxidation or corrosion damage to the metal layer. The protective layer also avoids affecting the anti-counterfeiting features of the element by using a perforated mark on the protective layer that is consistent with the metal layer.

[0029] 9. The anti-counterfeiting element provided by the present invention protects the base layer, metal layer and fluorescent layer through a first functional layer and a second functional layer arranged in parallel intervals, and facilitates the application of the anti-counterfeiting element to anti-counterfeiting products.

[0030] 10. The anti-counterfeiting product provided by the present invention has any of the above advantages because it uses the above-mentioned anti-counterfeiting elements. Attached Figure Description

[0048] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] 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.

[0052] This embodiment provides an anti-counterfeiting element that can superimpose multiple anti-counterfeiting features to form a specific anti-counterfeiting feature, thereby improving the anti-counterfeiting effect.

[0053] Example 1

[0054] like Figure 1 The image shows a specific implementation of an anti-counterfeiting element provided in this embodiment, comprising: a substrate 1, a metal layer 2, a fluorescent layer 3, and a magnetic layer 5. The metal layer 2 is disposed on the substrate 1 and has an identification area 4 with a hollowed-out pattern. The fluorescent layer 3 covers the identification area 4 of the metal layer 2. The magnetic layer 5 is disposed side by side with the fluorescent layer 3, and the metal layer 2 has an exposure area 6 for exposing the magnetic layer 5.

[0055] In use, the substrate 1 serves to support the metal layer 2, the fluorescent layer 3, and the magnetic layer 5, such as... Figure 3As shown, under white light transmission conditions, the transparent characters and / or patterns within the marking area 4 of the metal layer 2 can be seen from both the front and back. The magnetic layer 5 is typically made of colored magnetic ink, and the colored magnetic layer 5 within the exposed area 6 of the metal layer 2 can be seen from both the front and back. Under ultraviolet light conditions, under the action of the fluorescent layer 3, as... Figure 4 As shown, when viewed from the front, only the entire fluorescent patch 13 is visible. Under the combined effect of the overlapping of the fluorescent layer 3 and the marking area 4 of the metal layer 2, as... Figure 5 As shown, the fluorescent perforated pattern 12 can be seen when viewed from the reverse side; the metal layer 2 gives the element a conductive coding sequence that can be detected by a capacitive sensor, such as... Figure 6 As shown, within the marking area 4 of the metal layer 2, the capacitance undergoes pulse fluctuations due to the perforated pattern. These fluctuations can be detected by a capacitance sensor, thus forming a conductive code. The magnetic layer 5 endows the element with a magnetic code sequence detectable by a magnetic sensor. By detecting the magnetic layer 5, the sensor can identify the pulse fluctuations of magnetic flux on the magnetic layer, forming a magnetic code sequence. This magnetic anti-counterfeiting feature increases the diversity of anti-counterfeiting features and improves anti-counterfeiting performance. Furthermore, the combination of different coatings produces anti-counterfeiting features with varying effects, further enhancing the anti-counterfeiting effect. The anti-counterfeiting element provided in this embodiment solves the problems of existing multi-layer anti-counterfeiting elements where the anti-counterfeiting features generated by each coating do not interfere with each other, lack of innovation in anti-counterfeiting features, and low anti-counterfeiting performance.

[0056] Specifically, such as Figure 7 As shown, at the beginning of the magnetic layer 5, the magnetic flux changes from zero to one, forming the maximum amplitude A of the magnetic induced electromotive force. At the junction of the characters and / or patterns in the magnetic layer 5, due to different magnetic induction intensities, a change in the magnetic induced electromotive force is formed at that position. At the end of the magnetic layer 5, the maximum amplitude -A of the magnetic induced electromotive force is formed. This change in pulse can be detected by a magnetic sensor, forming a magnetic code.

[0057] It should be noted that, in this embodiment, the front side is as follows: Figure 1 As shown above, when viewed from the front, the order of the fluorescent layer 3 and the metal layer 2 is that the fluorescent layer 3 is seen first, followed by the metal layer 2; as shown above. Figure 1 The bottom side shown is the reverse side. When viewing the metal layer 2 and the fluorescent layer 3 from this reverse side, the metal layer 2 is seen first, followed by the fluorescent layer 3.

[0058] Specifically, the substrate 1 is paper or a transparent dielectric film, generally formed from a film material with good physicochemical resistance and high mechanical strength. It can be formed from plastic films such as polyethylene terephthalate (PET) film, polyethylene naphthalate (PEN) film, and polypropylene (PP) film, with PET being the preferred material. The metal layer 2 is an evaporated aluminum layer, copper layer, or other metal layer. The perforated pattern on the metal layer 2 is achieved through chemical etching, and the perforated pattern can be characters, graphics, or other special marking patterns. The fluorescent layer 3 can be an organic fluorescent material or an inorganic fluorescent material, and the width of the fluorescent layer is greater than or equal to the marking area 4.

[0059] like Figure 2 As shown, in the anti-counterfeiting element provided in this embodiment, the magnetic layer 5 has a pattern mark. Specifically, the pattern mark can be printed with colored magnetic ink, providing a visible colored mark 14. The pattern mark can be characters, graphics, or other special logo patterns. In use, under white light transmission conditions, such as Figure 3 As shown, the colored marks 14 formed by the pattern on the magnetic layer 5 can be seen from both the front and back, increasing the diversity of anti-counterfeiting features and improving anti-counterfeiting performance. Alternatively, as an alternative implementation, the magnetic layer 5 can also be a single, solid colored area.

[0060] like Figure 1 , Figure 2 As shown, in the anti-counterfeiting element provided in this embodiment, the exposed area 6 of the metal layer 2 is a completely hollowed-out area, or the exposed area 6 of the metal layer 2 is a partially hollowed-out area, and the pattern formed by the partially hollowed-out area is consistent with the pattern mark on the magnetic layer 5. With this configuration, the colored mark 14 on the magnetic layer 5 can be seen from both sides of the anti-counterfeiting element, increasing the diversity of anti-counterfeiting features and improving anti-counterfeiting performance. The exposed area 6 is a completely hollowed-out area, meaning that the exposed area 6 completely exposes the magnetic layer 5, avoiding the metal layer 2 from obstructing the magnetic layer 5. Specifically, the metal layer 2 is broken in the exposed area 6. Additionally, as an alternative implementation, such as... Figure 2 As shown, the magnetic layer 5 can also be set as a whole colored area, and the exposed area 6 of the metal layer 2 is set as a partially hollowed-out area. The partially hollowed-out area is set with a hollowed-out pattern. When viewed from the back, the block-shaped mark of the magnetic layer 5 can be seen, and when viewed from the front, the colored mark 14 produced by the combined action of the magnetic layer 5 and the metal layer 2 can be seen.

[0061] like Figure 6As shown, the capacitance changes from zero to one at the beginning of the metal layer 2, forming a maximum value B, and the capacitance changes from one to zero at the end of the metal layer 2, forming a maximum value -B. Within the marking area 4 of the metal layer 2, the capacitance forms pulse fluctuations due to the influence of the hollow pattern. This fluctuation change can be detected by a capacitance sensor, thereby forming a conductive code.

[0062] In the anti-counterfeiting element provided in this embodiment, the magnetic layer 5 is made of a magnetically conductive material. This magnetically conductive material can provide a magnetic coding sequence while simultaneously enabling the magnetic layer to provide a conductive coding sequence, which, when superimposed with the conductive coding of the metal layer 2, generates a new conductive coding sequence, thus improving anti-counterfeiting performance.

[0063] In the anti-counterfeiting element provided in this embodiment, the magnetic layer 5 is made of hard magnetic material or soft magnetic material. Using hard or soft magnetic material to make the magnetic layer 5 allows for the generation of different magnetic coding sequences depending on the material's characteristics. Hard magnetic materials are difficult to demagnetize after magnetization and have high residual magnetic induction intensity. During detection, they are typically magnetized first by an excitation device and then detected by a magnetic sensor, making them suitable for conventional anti-counterfeiting devices. Soft magnetic materials are easily demagnetized after magnetization, requiring simultaneous magnetization and detection, making them unsuitable for conventional anti-counterfeiting devices. Specifically, the magnetic layer 5 can be iron oxides such as Fe3O4, barium ferrite, strontium ferrite, AlNiCo alloy, magnetic conductive ink, or any other substance with hard and / or soft magnetic characteristics. Alternatively, as an alternative implementation, the magnetic layer 5 can also be made of a non-conductive magnetic material.

[0064] like Figure 1 As shown, the anti-counterfeiting element provided in this embodiment also includes a protective layer 8, disposed between the metal layer 2 and the fluorescent layer 3. The protective layer 8 has a perforated pattern with the same shape as the perforated pattern on the identification area 4 of the metal layer 2. The protective layer 8 protects the metal layer 2 from oxidation or corrosion damage. The perforated markings on the protective layer 8, consistent with those on the metal layer 2, prevent the protective layer 8 from obscuring the anti-counterfeiting features of the element. Alternatively, as an alternative implementation, the protective layer 8 can be omitted, or an entire perforated area can be provided on the protective layer 8 to expose the perforated characters and / or patterns on the metal layer 2.

[0065] like Figure 1As shown, the anti-counterfeiting element provided in this embodiment includes a first functional layer 9 and a second functional layer 10 arranged in parallel intervals. The substrate 1, the metal layer 2, and the fluorescent layer 3 are disposed between the first functional layer 9 and the second functional layer 10. The first functional layer 9 and the second functional layer 10, arranged in parallel intervals, protect the substrate, the metal layer 2, and the fluorescent layer 3, and facilitate the application of the anti-counterfeiting element to anti-counterfeiting products. Specifically, the first functional layer 9 and the second functional layer 10 are white coatings, conductive coatings, OVI coatings, or metallic ink coatings.

[0066] Working principle:

[0067] like Figure 1 As shown, the anti-counterfeiting element provided in this embodiment, when viewed from both the front and back under white light transmission conditions, reveals the light-transmitting hollow pattern 11 of the metal layer 2 and the colored mark 14 of the magnetic layer 5. Under ultraviolet light conditions, when viewed from the back, the hollow mark of the metal layer 2 and the fluorescent layer 3 work together to create a fluorescent hollow pattern 12. When viewed from the front, fluorescent color blocks 13 with the same shape as the fluorescent layer 3 can be seen. Furthermore, the conductive coding sequence of the metal layer 2 can be detected by a capacitive sensor, and the magnetic coding sequence of the magnetic layer 5 can be detected by a magnetic sensor. Through various combinations, the anti-counterfeiting performance is improved.

[0068] In addition, this embodiment also provides an anti-counterfeiting product that uses the anti-counterfeiting elements described in the above embodiments to achieve multiple anti-counterfeiting feature combinations and improve anti-counterfeiting performance.

[0069] Example 2

[0070] like Figure 8 As shown, this embodiment provides an anti-counterfeiting element, including: a substrate 1, a metal layer 2, a fluorescent layer 3, and a magnetic layer 5. The metal layer 2 is disposed on the substrate 1 and has a marking area 4 formed by hollowed-out characters and / or patterns. The fluorescent layer covers the marking area of ​​the metal layer 2. The magnetic layer 5 is disposed side by side with the fluorescent layer 3. The metal layer 2 has an exposed area 6 for exposing the magnetic layer 5. The exposed area 6 of the metal layer 2 is a partially hollowed-out area with characters and / or patterns. The magnetic layer is configured as a block shape without characters and patterns.

[0071] A masking layer 7 is also provided on the side of the magnetic layer 5 away from the metal layer, and the masking layer 7 completely covers the magnetic layer. The masking layer 7 is an ink coating with a masking effect. Using an ink coating with a masking effect as the masking layer 7 can block the colored magnetic layer 5, improving the aesthetics of the component. It also includes a first functional layer 9 and a second functional layer 10 arranged in parallel and spaced apart, with the substrate 1, metal layer 2, fluorescent layer 3, magnetic layer 5, and masking layer 7 disposed between the first functional layer 9 and the second functional layer 10.

[0072] Under white light transmission conditions, such as Figure 9 As shown, viewed from the reverse side, a translucent perforated pattern 11 and a colored mark 14 formed by the overlap of the exposed area 6 and the magnetic layer 5 are visible, as shown. Figure 10 As shown, when viewed from the front, only the translucent perforated pattern 11 can be observed; under ultraviolet light, as... Figure 11 As shown, viewed from the reverse side, the hollowed-out characters and / or patterns of the metal layer 2, together with the fluorescent layer 3, create a fluorescent hollowed-out pattern 12, as shown. Figure 12 As shown, when viewed from the front, the entire fluorescent patch 13 can be seen; the conductive coding sequence of the metal layer 2 is detected by a capacitive sensor, such as... Figure 13 As shown, the capacitance signal of the metal layer 2 changes due to the influence of hollowed-out characters and / or patterns within the marking area 4 and exposed area 6. This pulse change can be detected by a capacitance sensor, forming a conductive code. The magnetic code sequence of the magnetic layer 5 is detected by a magnetic sensor, such as... Figure 14 As shown, at the beginning of magnetic layer 5, the magnetic flux changes from zero to one, forming the maximum amplitude A of the magnetic induced electromotive force. At the end of magnetic layer 5, the maximum amplitude -A of the magnetic induced electromotive force is formed. This change in pulse can be detected by a magnetic sensor, forming a magnetic code.

[0073] It should be noted that, in this embodiment, the front side is as follows: Figure 8 As shown above, when viewed from the front, the order of the fluorescent layer 3 and the metal layer 2 is that the fluorescent layer 3 is seen first, followed by the metal layer 2; as shown above. Figure 10 The bottom side shown is the reverse side. When viewing the metal layer 2 and the fluorescent layer 3 from this reverse side, the metal layer 2 is seen first, followed by the fluorescent layer 3.

[0074] 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.
