It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0052] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0053] Refer to the following Figures 1 to 6 According to some embodiments of the present invention.

[0054] like Figure 1 、 Figure 2 As shown, an embodiment of the first aspect of the present application provides a transparent anti-counterfeiting element 10, comprising a transparent material layer 100 and multiple anti-counterfeiting dielectric layers 110. Specifically, the transparent material layer 100 has a patterned grid concave-convex structure, which includes multiple grooves. The multiple anti-counterfeiting dielectric layers 110 are disposed in the grooves, and the anti-counterfeiting dielectric layers 110 include one of the following: a magnetic material layer, a fluorescent material layer, a dielectric material layer, or an infrared material layer.

[0055] The transparent anti-counterfeiting element 10 provided in this embodiment includes a transparent material layer 100 and multiple anti-counterfeiting dielectric layers 110. The transparent material layer 100 has a patterned fine grid concave-convex structure, which includes multiple grooves. The anti-counterfeiting dielectric layers 110 fill the grooves, forming a patterned anti-counterfeiting feature network. There are multiple anti-counterfeiting dielectric layers 110, which can be a combination of two or more of the following: magnetic material layers, fluorescent material layers, dielectric material layers, and infrared material layers. By combining these different material layers, a clear anti-counterfeiting feature signal can be presented under appropriate detection equipment, thereby improving the anti-counterfeiting and concealment effects.

[0056] Specifically, different combinations of magnetic material layers can be used for magnetic encoding; the combination of magnetic material layers and fluorescent material layers can present overprinting and counter-printing effects under the action of different excitation sources 220, that is, a clear complete network pattern is presented under high-resolution imaging equipment, and a clear partial network pattern is presented under different effects such as ultraviolet light source or magnetic imaging. The anti-counterfeiting medium layer 110 containing dielectric material can be used as an antistatic layer. The transparent conductive layer has high transparency and high conductivity, and obvious conductive signal characteristics can be identified using a smartphone APP or mini-program. The transparent conductive layer can play a good antistatic role in the printing process, and can ensure the transparency and antistatic performance of the window area, so the window size design will not be affected. Among them, the transparent material layer 100 is a single-sided transparent material layer or a double-sided transparent material layer.

[0057] In the above embodiment, multiple anti-counterfeiting medium layers 110 can be filled in different grooves respectively, or multiple anti-counterfeiting medium layers 110 can be filled in layers in the same groove. For example, if the groove of the transparent material layer 100 is filled with the first anti-counterfeiting medium layer 110, and the upper portion of the first anti-counterfeiting medium layer 110 is fully or partially filled with the second anti-counterfeiting medium layer 110, the transparent anti-counterfeiting element 10 can simultaneously have two signals. Alternatively, the groove of the transparent material layer 100 can be partially filled with the first anti-counterfeiting medium layer 110, partially filled with the second anti-counterfeiting medium layer 110, and the third anti-counterfeiting medium layer 110 is filled above the first and second anti-counterfeiting medium layers 110, and so on.

[0058] Furthermore, the transparent material layer 100 includes a transparent flexible base layer and a transparent gelatin layer. The transparent gelatin layer has a patterned grid concave-convex structure for filling the anti-counterfeiting medium layer 110. The transparent gelatin layer is located on one or both sides of the transparent flexible base layer, so that the anti-counterfeiting medium layer 110 can be filled on one side or both sides.

[0059] In some embodiments, the transparent security element 10 has a thickness of less than or equal to 250 μm and can be applied to security items 120 such as banknotes, plastic banknotes, and passports. Obvious moiré patterns can be seen when the transparent security element 10 is folded and observed through light or under ultraviolet light.

[0060] In some embodiments, the grid concave-convex structure includes multiple unit grids of the same or different shapes and sizes, which are combined to form one or more anti-counterfeiting feature networks. The unit grids are outlined as grooves filled with an anti-counterfeiting medium, and the interior of the unit grids is a raised portion of the transparent material layer 100. The outline has a line width of less than 30 μm. The width of the unit grid is greater than or equal to the minimum line width of the outline. The thickness of the anti-counterfeiting medium layer 110 is 1 μm to 20 μm.

[0061] The particle size of the material of the anti-counterfeiting medium layer 110 is smaller than the minimum line width of the unit grid, so that the anti-counterfeiting medium layer 110 can be filled into the unit grid.

The transparent security element 10 is applied to one side of the transparent window 130 or the printed ink layer 150, thereby providing the security article 120 with an anti-counterfeiting effect. The transparent security element 10 can also be combined with holographic or optically variable inks and applied to the transparent window 130, the wide strip 140, the security thread, and the label. The base layer 260 is selected from polymer films (PI films, PET films, BOPP films, TAC films), paper, synthetic paper, fabrics, non-woven fabrics, metal foils, metal plates, metal-plated sheets (films), and multilayer composite sheets formed by combinations of the above materials.
