Embodiment Construction
[0042] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0043] figure 1 It is a schematic diagram of an anti-counterfeit paper according to an embodiment of the present invention. figure 2 for figure 1 The A-A profile of the anti-counterfeiting paper. Such as figure 1 and figure 2 As shown, the anti-counterfeiting paper includes a paper layer 1, a substrate layer 2 and an information layer 3, the information layer 3 is located between the paper layer 1 and the substrate layer 2, and there are hollow areas 5 on the paper layer 1 and the information layer 3, The hollow area 5 forms a hollow pattern 7 on the paper layer 1 and the information layer 3, the hollow pattern 7 includes the hollow pattern 701 of the paper layer 1 and the hollow pattern 702 of the information layer 3, and the hollow pattern 701 of the paper layer 1 It completely coincides with the hollow patter...

The invention provides an anti-counterfeiting paper. The anti-counterfeiting paper includes a paper layer, a substrate layer and an information layer. The information layer is located between the paper layer and the substrate layer. Hollow patterns are arranged on the paper layer and the information layer. The hollow patterns are completely overlapped, the hollow patterns are at least partially disconnected from the main body of the paper layer and / or the main body of the information layer, and the hollow patterns are covered by the substrate layer. The anti-counterfeiting paper has double visual effects of paper pattern and information layer pattern, and the above two patterns are completely overlapped, showing a unique feature of "front and back printing". The anti-counterfeiting paper has the advantages of being difficult to copy and easy to identify.
Description
technical field [0001] The invention belongs to the field of anti-counterfeiting, and in particular relates to an anti-counterfeiting paper and a manufacturing method thereof. Background technique [0002] Window anti-counterfeiting technology was first applied on plastic banknote substrates. Because of its unique appearance and excellent anti-counterfeiting effect, it has attracted widespread attention. The paper substrate also introduces window features through a variety of composite methods. [0003] The method of forming the window on the paper may be to form an opening on the paper first, and then cover the area of the opening to form a composite security element, such as WO2005 / 095118. In this method, opening holes and making a dealuminated transparent plastic film are two separate steps, and it does not have the visual anti-counterfeiting method that effectively combines the opening holes and the patterns on the film to become difficult to replicate. [0004] The...
