Problems solved by technology

Most of the current first-line anti-counterfeiting technologies are simple in principle, with a wide supply of anti-counterfeiting raw materials, and are easily imitated by counterfeiters, while second-line anti-counterfeiting requires special tools for identification, which is inconvenient and difficult to be accepted by consumers.

Embodiment 1

[0077] The structure of the anti-counterfeit label 50 of embodiment 1 is as Figure 12 to Figure 14 As shown, it includes a base layer 510 , a color separation layer 530 , an adhesive coating layer 550 , a debonding layer 570 , a second adhesive layer 580 and a peeling layer 590 .

[0078] Wherein, the base layer 510 is PET.

[0079] The color separation layer 530 is stacked on the surface of the base layer 510 and includes a color separation part 531 , a graphic part and a background part 533 . The background part 533 is adjacent to the color separation part 531 and the graphic part and is arranged around the color separation part 531 . The color separation part 531 is printed by color separation ink, and the color separation ink is formed by mixing base ink with blue guaiazulene. The basic ink is Shennissin Jinguan red ink, which is red (second color), guaiazulene is blue (third color), and the color separation ink is purple. Graphic part is transparent and colorless. The...

Embodiment 2

[0087] The color separation part of the anti-counterfeit label of Example 2 observed through the isolation layer is green, and the structure of the anti-counterfeit label of Example 2 is roughly the same as that of the anti-counterfeit label of Example 1. The difference is that the base ink used in this implementation is Enmei 1301 Yellow ink is yellow, and color separation ink is green.

Embodiment 3

[0089] The color separation part of the anti-counterfeiting label of Example 3 observed through the isolation layer is blue-gold, and the structure of the anti-counterfeiting label of Example 3 is roughly the same as that of the anti-counterfeiting label of Example 1. The difference is that the base ink of this implementation is Ahesi The 2000 series of gold inks is golden, and the color separation ink is blue and gold.

Abstract

The invention relates to an anti-counterfeiting label. The anti-counterfeiting label comprises a base layer, a color separation layer and an adhesive layer. The color separation layer is laminated onthe base layer, the color separation layer comprises a color separation portion and an image-text portion, the color separation portion is adjacent to the image-text portion, and the color separationportion contains volatile dye. The adhesive layer laminated on the color separation layer comprises a first adhesive layer and an isolation layer, the first adhesive layer has a first color, the firstadhesive layer is laminated on the color separation layer and completely covers the color separation portion, the first adhesive layer is capable of adsorbing the volatile dye of the color separationportion to form an adsorption region with a color different from the first color, thus the color separation portion presents the color different from that of the image-text portion, and projection ofthe adsorption region on the color separation layer completely coincides with that of the color separation portion, the isolation layer is laminated on one side, away from the color separation layer,of the first adhesive layer, and the isolation layer can prevent the penetration of the volatile dye. The anti-counterfeiting label is difficult to counterfeit, and has high anti-counterfeiting function.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting, in particular to an anti-counterfeiting label. Background technique [0002] At present, anti-counterfeiting technology can be divided into first-line anti-counterfeiting and second-line anti-counterfeiting according to the convenience of anti-counterfeiting. First-line anti-counterfeiting refers to the anti-counterfeiting technology that ordinary consumers can distinguish and identify with simple methods such as hand feeling or visual inspection without using special technical instruments. Second-line anti-counterfeiting is a kind of identification that is difficult to identify and requires the help of special instruments and equipment. anti-counterfeiting technology. Most of the current first-line anti-counterfeiting technologies are simple in principle, with a wide supply of anti-counterfeiting raw materials, which are easily imitated by counterfeiters, while second-line anti-counterfeiting...
