Anti-counterfeit label for random three-dimensional mirror surface graph and preparing method thereof

Abstract

The invention discloses an anti-counterfeit label for a random three-dimensional mirror surface graph and a preparing method thereof. The preparing method comprises the steps that a substrate layer is prepared; a random three-dimensional mirror surface layer is manufactured on the substrate layer; a random graph information enhancing layer is manufactured; the manufactured random graph information enhancing layer is bonded to the random three-dimensional mirror surface layer through a binding agent; a graph layer is printed on the surface of the random graph information enhancing layer; the substrate layer, the random three-dimensional mirror surface layer, the random graph information enhancing layer and the graph layer are sequentially arranged from bottom to top. The random three-dimensional mirror surface layer and the random graph information enhancing layer are of three-dimensional random structures completely, and different kinds of graph information are obtained under different light conditions, and can not be copied at all; when people try to transplant the label, the substrate layer will be fractured to cause damage to the random three-dimensional mirror surface layer, so that the graph information characteristic of the label is damaged. The anti-counterfeit label has the advantages of being high in anti-counterfeit strength, can not be copied or transplanted, and has wide application value in the technical field of counterfeit prevention.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting, in particular to an anti-counterfeiting label with random three-dimensional mirror surface graphics and a preparation method thereof. Background technique [0002] Anti-counterfeiting technology is an interdisciplinary technology involving many technical fields. With the rapid development of market economy, merchants pay more and more attention to the protection of intellectual property rights, and require their product labels to have corresponding anti-counterfeiting functions. At the same time, because counterfeit and counterfeit goods are flooding the market, which seriously threatens the rights and interests of consumers, there is an urgent need in the fields of tobacco and alcohol, food, medicine, health care products, cosmetics, clothing, pesticides, fertilizers, auto parts, seeds, etc. anti-counterfeiting and verification requirements. There are various anti-counterfeiting te...
