Problems solved by technology

There are many improvements similar to the above-mentioned anti-counterfeiting fibers, but they mainly focus on improving the anti-counterfeiting effect by adding photosensitive color-changing pigments of various colors. Although this enhances the easy identification of anti-counterfeiting fibers, due to the Anti-counterfeiting inks of different colors need to be added, and the production process is cumbersome

Embodiment 1

[0047] Please refer to figure 1 , 2 , an anti-counterfeiting material provided by the present invention comprises a fiber 1, on the fiber 1, three photosensitive color-changing particles 2 are distributed at equal intervals along the length direction of the fiber 1. The photosensitive color-changing particles can only be distributed in a dispersed state, and they are arranged at intervals on the fiber 1, so that the arrangement of the photosensitive color-changing particles 2 becomes regular and can be arranged in a straight line, which enhances the easy identification and differentiation, and also It increases the difficulty of imitation and has excellent anti-counterfeiting effect.

[0048] The photosensitive color-changing particles 2 are ultraviolet photosensitive color-changing particles, which are obtained by curing the anti-counterfeiting ink (commercially available UV ink is used in the present invention) by ultraviolet light. Fluorescence occurs under UV light irrad...

Embodiment 2

[0058] The only difference between this embodiment and Embodiment 1 is that infrared photosensitive discoloration particles are used, and PET fibers are used as fibers for use in infrared anti-counterfeiting technology.

Embodiment 3

[0060] The only difference between this embodiment and Embodiment 1 is that solar photosensitive color-changing particles are used, and PP fibers are used as fibers for use in sunlight anti-counterfeiting technology.

Abstract

The invention discloses an anti-counterfeit paper. The anti-counterfeit paper comprises a paper body and an anti-counterfeit material loaded on the paper body, the anti-counterfeit material comprises a fiber, and at least two photochromic particles are distributed on the fiber along the length direction of the fiber at intervals. The anti-counterfeit material in the anti-counterfeit paper is different from common anti-counterfeit fiber materials in structures, can be easily distinguished, is difficult to imitate, and has very good recognizability only through a single anti-counterfeit ink.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting, in particular to anti-counterfeiting paper. Background technique [0002] Fluorescent anti-counterfeiting fiber is an anti-counterfeiting material widely used in various paper products. It mainly uses photosensitive color-changing ink on the surface of fiber bundles to form a photosensitive color-changing layer, which emits light under the irradiation of ultraviolet and infrared light beams in specific bands. Bright, after the fluorescent anti-counterfeiting fiber is loaded on the paper, the anti-counterfeiting function is played through the above-mentioned specific photosensitive mark, so as to obtain the anti-counterfeiting paper with anti-counterfeiting function. [0003] As far as the loading method of anti-counterfeiting fibers in anti-counterfeiting paper is concerned, there are mainly two types. One is that fluorescent anti-counterfeiting fibers are directly mixed into pulp dur...
