Problems solved by technology

[0004] However, in the prior art, the ability of these two printing inks to adapt to many different materials is very weak, and it is impossible to mark products of many different materials.
When the marked product is transported and stored, the color will fade due to the product being pulled or rubbed, or the color will be scattered due to moisture, or the color of the pattern will become lighter, or the response to light will not be sensitive enough. The conditions are ordinary, and it is easy to be counterfeited, which causes great inconvenience to the process of anti-counterfeiting identification of products, and even fails to achieve the purpose of anti-counterfeiting identification

Abstract

The invention relates to the field of printing ink of anti-counterfeiting label, especially to fluorescent stamp-pad ink with an anti-counterfeiting function and a preparation method thereof. The fluorescent stamp-pad ink with the anti-counterfeiting function is composed of a film-forming material and a fluorescent liquid, and is characterized in that the fluorescent liquid comprises the following ingredients, by weight, 15-20 parts of castor oil, 10-15 parts of terbium nitrate, 25-30 parts of 2,4-dihydroxy-benzoic acid, 150-200 parts of triethylamine, 150-200 parts of industrial alcohol solvent and 250-300 parts of n-butyl alcohol. The fluorescent stamp-pad ink prepared by the preparation method has stable print performance, is rapid and accurate in distinguishing true-false, and has good stability and adhesiveness. Print is clear and uniform and has little diffusion. The print can emit fluorescence under ultraviolet illumination, and the fluorescent color is obvious and clear and has good differentiability. Anti-counterfeiting identification can be achieved according to the fluorescent color.

Description

technical field [0001] The invention relates to the field of printing ink for anti-counterfeiting marks, in particular to a fluorescent printing ink with anti-counterfeiting function and a preparation method thereof. Background technique [0002] As a tool for distinguishing the authenticity of products in daily life, anti-counterfeiting marks are widely used in the field of product mark anti-counterfeiting because of their simple setting and fast distinguishing process. [0003] In daily life, it is common to use ink to print anti-counterfeiting marks to achieve the purpose of anti-counterfeiting. This method needs to use printing ink for printing. Use special lighting to show the marking pattern, so as to distinguish and mark. [0004] However, in the prior art, these two printing inks are weak in adapting to multiple different materials, and cannot mark products of multiple different materials. When the marked product is transported and stored, the color will fade due t...
