[0002] Water transfer printing paper is a kind of paper with a weight of 120 grams to 300 grams coated with a layer of PVA water-soluble coating. The usage method is to soak it in tap water for about 1 minute until the PVA dissolves in water, and the paper serves as a carrier to separate the pattern from the base paper and then transfer it to the printing substrate, realizing the sticker with the principle of indirect printing. Anti-counterfeiting water transfer printing paper is a label with anti-counterfeiting function. Ordinary stickers on the market are relatively easy to imitate, and ordinary stickers cannot achieve the effects of anti-fouling, anti-wearing, and anti-breaking during use. Therefore, diversified anti-counterfeiting and protecting the complete display of the anti-counterfeiting pattern on its surface are of great significance for its difficult imitation and anti-counterfeiting effect protection.
[0003] However, the anti-counterfeiting ability of traditional water transfer printing paper is relatively single, and it is extremely easy to be imitated by simple anti-counterfeiting structures for anti-counterfeiting identification.

[0019] See Figures 1 - 3 As shown, the present specific embodiment adopts the following technical solution: It includes a water-soluble paper layer 1, a screen printing and bronzing base oil layer 2, a multi-layer anti-counterfeiting printing layer 3, a photochromic laser anti-counterfeiting bronzing film layer 4, a four-color ink graphic printing layer 6, a transparent protective varnish printing layer 7, and a peelable film protective layer 8; The upper surface of the water-soluble paper layer 1 is connected to the multi-layer anti-counterfeiting printing layer 3 through the screen printing and bronzing base oil layer 2. One side of the upper end of the multi-layer anti-counterfeiting printing layer 3 is provided with a photochromic laser anti-counterfeiting bronzing film layer 4, a four-color ink graphic printing layer 6, a transparent protective varnish printing layer 7, and a peelable film protective layer 8; Among them, the multi-layer anti-counterfeiting printing layer 3 is composed of a background pattern printing layer 31 and an anti-counterfeiting printing layer 32. A nano-sheet photosensitive ink anti-counterfeiting printing layer 33 is arranged in the middle of the anti-counterfeiting printing layer 32. The background pattern printing layer 31 and the nano-sheet photosensitive ink anti-counterfeiting printing layer 33 cooperate to form a complete anti-counterfeiting pattern.

And there is a staggered structure between the nano-sheet photosensitive ink anti-counterfeiting printing layer 33 and the background pattern printing layer 31, and the staggered structure physical anti-counterfeiting structure can be observed from the side.
