Problems solved by technology

At present, the general paper anti-counterfeiting labels are pasted on the product packaging, but counterfeiters often use various means to replace the genuine packaging with counterfeit products, making genuine packaging and fake products, which infringes on brand manufacturers and consumers. In addition, these anti-counterfeiting technologies are no longer valuable in the second-hand trading market

Abstract

The invention provides a method for implementing lifelong anti-counterfeiting of commodities. The method comprises the following steps: mixing an epoxy resin glue A, an epoxy resin glue B or other commercial glues (such as PP glue and PVC glue) and rare-earth up-converting luminescent micro / nano-materials according to a mass ratio of 3: 1: (0.2-1.5) or 1: (0.2-1.5) to obtain anti-counterfeiting materials; coating or 3D printing the anti-counterfeiting materials onto surfaces of commodities in need of counterfeiting so as to form various patterns, curing the commodities to obtain commodities with patterns; exciting the commodities with patterns with adoption of 980 nm near-infrared light, and judging the authenticity of the commodities in a way that the patterns with particular colors are visible to naked eyes or the wavelengths of emitted lights are detected by an instrument. According to the method, the anti-counterfeiting materials can be coated or 3D printed onto the metal, glass, leather, wood, plastics, ceramics, textiles, paper and other interfaces; the method can implement the lifelong anti-counterfeiting of commodities, is simple in operation, and is good in anti-counterfeiting effect.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting, and in particular relates to a method for realizing lifelong anti-counterfeiting of commodities. Background technique [0002] Anti-counterfeiting technology is a measure taken to achieve the purpose of anti-counterfeiting. It can accurately identify the authenticity within a certain range without being imitated and copied. At present, the general paper anti-counterfeiting labels are pasted on the product packaging, but counterfeiters often use various means to replace the genuine packaging with counterfeit products, making genuine packaging and fake products, which infringes on brand manufacturers and consumers. In addition, these anti-counterfeiting technologies no longer have value in the second-hand trading market. Contents of the invention [0003] The technical problem to be solved by the present invention is how to develop an anti-counterfeiting technology that can be marked...
