Abstract

The invention relates to a preparation method of an electroluminescent anti-counterfeiting trademark structure. The method includes the steps that electroluminescent nano-particles are dispersed in amixed solvent of water, ethylene glycol and a polymer through ultrasonic or mechanical stirring so as to be prepared into printing ink for printing an electroluminescent layer; then, a first conductive ink layer, an electroluminescent layer and a second conductive ink layer are printed on release paper layer by layer through the silk-screen printing technology or the letterpress printing technology to form the electroluminescent anti-counterfeiting trademark structure; the prepared electroluminescent anti-counterfeiting trademark structure is detected through a detector with a commercial button cell as a power source, and an electroluminescent anti-counterfeiting trademark is stimulated through physical contact to emit light and serve as the anti-counterfeiting basis. Characteristics are excellent, the formula of printing ink is difficult to copy, and the anti-counterfeiting performance of a printed product is greatly improved; a color pattern can be displayed only under the excitationof detection equipment, so that higher invisibility and anti-counterfeiting performance are achieved.

Description

technical field [0001] The invention relates to a method for preparing a novel anti-counterfeit trademark structure by using electroluminescent ink, and belongs to the technical field of anti-counterfeit trademarks. Background technique [0002] Counterfeit and shoddy products not only destroy the normal market order and the brand image of enterprises, but also greatly damage the economic interests of the people, and even more seriously, may endanger people's lives. In recent years, nearly a quarter of household consumers in Chinese cities have been damaged, involving about 50 million urban consumers. The proliferation of counterfeit and low-quality goods will become an unstable factor hindering social progress and stability. Therefore, the continuous development of new anti-counterfeiting marking technology can ensure the safety and stability of my country's market and the people's living and working in peace and contentment. [0003] According to the technical characteri...
