Novel anti-counterfeit mark and manufacturing method thereof

Abstract

The invention provides a novel anti-counterfeit mark. The novel anti-counterfeit mark comprises an anti-counterfeit mark base and an invisible anti-counterfeit pattern, wherein the regional difference is formed through micro-nano materials and the anti-counterfeit mark base, so that the invisible anti-counterfeit pattern is formed, the surface of the anti-counterfeit mark base comprises an invisible anti-counterfeit pattern area and a non-pattern area, the invisible anti-counterfeit pattern area or the non-pattern area is composed of a film layer formed on the surface of the anti-counterfeit mark base through micro-nano materials, and the micro-nano materials include organic particles, inorganic particles, photoresist, photosensitive resin, metal, alloy, ceramic, polymer, active micromolecules, an oxide, a sulfide, a nitride and a carbide or a binary compound or polycompound composed of III-V or II-IV or IV-VI elements. According to the novel anti-counterfeit mark, the invisible anti-counterfeit pattern can appear when the anti-counterfeit mark is located at the position of an air blowing opening or encounters with water or steam, the invisible anti-counterfeit pattern can become invisible after water is volatilized, and the anti-counterfeit mark can be used for counterfeit prevention in the fields such as the medicine field, the food safety field and the financial field. The invention further provides a manufacturing method of the novel anti-counterfeit mark.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting technology, in particular to a novel anti-counterfeiting label and a preparation method thereof. Background technique [0002] According to the "2013-2017 China Anti-Counterfeiting Industry Market Prospect and Investment Opportunity Analysis Report", the global market affected by counterfeit and shoddy products has reached 300 billion US dollars, and the annual turnover of counterfeit and shoddy products has accounted for 10% of the total world trade. In my country, the scale of counterfeit and shoddy products is 300-400 billion RMB, especially in industries such as tobacco, alcohol, agricultural trade, food, and cosmetics, which have become the hardest hit areas for counterfeit and shoddy products. Therefore, the anti-counterfeiting industry has become a sunrise industry in the 21st century. [0003] At present, the market capacity of my country's anti-counterfeiting industry has reached 800 b...
