Abstract

The invention provides a sheet-like anti-counterfeiting material, and the sheet-like anti-counterfeiting material adopts a special-shaped structure except for positive quadrilateral; the sheet-like anti-counterfeiting material comprises the following layered structures: a paper-based anti-counterfeiting carrier layer, wherein the paper-based anti-counterfeiting carrier is paper prepared by remixing at least two fibers; and a anti-counterfeiting layer. The invention also provides a preparation method of the sheet-like anti-counterfeiting material, and anti-counterfeiting paper containing the sheet-like anti-counterfeiting material. Based on the sheet-like anti-counterfeiting material of the invention, anti-counterfeiting paper can be obtained with multi-level anti-counterfeiting functions of visual identification, rapid machine-reading, and expert analysis.

Description

technical field

[0001] The invention relates to a paper anti-counterfeiting material, which belongs to the technical field of paper anti-counterfeiting. Background technique

[0002] Using sheet materials to carry anti-counterfeiting substances is one of the effective ways for paper to realize anti-counterfeiting function.

[0003] In the prior art, there is a sheet-shaped anti-counterfeiting material composed of a paper carrier and an anti-counterfeiting layer, but the paper carrier involved is only a carrier of the anti-counterfeiting layer and does not have anti-counterfeiting performance itself.

[0004] A fluorescent fiber paper is also disclosed in the prior art. In the structure of the anti-counterfeiting mark, the substrate layer is a fluorescent fiber paper provided with colored fibers and / or fluorescent fibers visible under ultraviolet light, which has a certain anti-counterfeiting function. However, the anti-counterfeiting function possessed by the fluorescent fi...
