Problems solved by technology

Traditional anti-counterfeiting technologies, such as paper pattern anti-counterfeiting technology, bar code technology, two-dimensional code technology, chemical ink anti-counterfeiting technology or texture anti-counterfeiting technology etc. The engraving method is time-consuming and labor-intensive, and the anti-counterfeiting effect is general), although it can also achieve a certain anti-counterfeiting purpose, but the technical threshold is low and it is easy to imitate
Therefore, this does not restrict the circulation of fake cigarettes and imitation cigarettes very well.

Abstract

The invention discloses an anti-counterfeit material, which is composed of photosensitizer iodofluoroboron pyrrole dye, acceptor perylene, polymer carrier and solvent; the polymer carrier is polyethylene oxide and polymethyl methacrylate composition of the mixture. The molar ratio of the photosensitizer to the acceptor is 1:5-20, and the mass of the polymer carrier is 1000-3000 times that of the acceptor. The present invention also provides the application of the anti-counterfeiting material in cigarettes. The application of the above-mentioned anti-counterfeit material in cigarettes, specifically, the anti-counterfeit material can be coated on the surface of the cigarette packaging box, and after drying, an up-conversion luminescent film with uniform texture can be formed. When the upconversion luminescent film is irradiated with a green laser pointer, it emits blue-violet light with anti-Stokes shift properties and energy higher than the excitation wavelength through the triplet-triplet annihilation upconversion mechanism, and its special luminescence properties It is not easy to be imitated or copied, so it can play a good anti-counterfeiting effect.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting, and in particular relates to a luminous anti-counterfeiting material, a preparation method thereof and an application in cigarettes. Background technique [0002] The profit margin of tobacco products is huge, and at the same time it involves the vital interests of many consumers and the fiscal revenue of the country. The proliferation of counterfeit cigarettes not only affects the consumers' pursuit of the quality of cigarette smoking, seriously endangers the physical and mental health of consumers, but also leads to the loss of national tax revenue. In order to limit the flow of counterfeit smoking products into the market, and even cause an impact on commercially available real cigarettes, it is necessary to add anti-counterfeiting technology to the smoking products. Traditional anti-counterfeiting technologies, such as paper pattern anti-counterfeiting technology, bar code techno...
