Problems solved by technology

[0003] The invisible ink used by the printing equipment is printed on the surface of the porous medium. Because the ink droplets are small and the printing area formed on the surface of the medium is small, the identification information formed by the ink will diffuse into the medium during long-term storage. , so that the identification information is blurred or even disappears, which is not conducive to effective reading of the identification information, which in turn affects the information monitoring or traceability of the product corresponding to the identification information

Abstract

The invention provides dual-anti-counterfeiting jet printing ink. The ink is prepared from, by weight, 0.40.8% of ultraviolet absorption fluorescent material, 0.05-0.07% of infrared absorption material, 3-7% of high molecular weight resin, 4-16% of low molecular weight resin, 1-1.5% of conductive agent and solvents, wherein the weight-average molecular weight of the high molecular weight resin is 12,000-60,000, and the weight-average molecular weight of the low molecular weight resin is 300-1,600; the solvents include the keto solvent, the alcohol solvent, the ester solvent and alcohol ether solvent; the total weight percentage of the components is 100%. The jet printing ink is an ink system with the high solid content, the mass of ink drops printed on a medium is increased exponentially, the recognition capability of ultraviolet and infrared under recognition means can be improved, and the defect that the identifiability is lost due to diffusion of the ink can be avoided.

Description

technical field [0001] The invention relates to a jet printing ink, in particular to a double anti-counterfeit jet printing ink. Background technique [0002] At present, there are many anti-counterfeiting methods, and the commonly used anti-counterfeiting methods involving invisible anti-counterfeiting include ultraviolet, infrared, thermochromism, chemical discoloration and other anti-counterfeiting methods. Single-use UV anti-counterfeiting is easy to be identified, thus being imitated or destroyed. Infrared and chemical discoloration are not easy to detect, but it is also not easy to detect if there is a spray during the printing process. Thermochromic ink systems are all water-based systems and are not suitable for printing equipment, such as inkjet printers. [0003] The invisible ink used by the printing equipment is printed on the surface of the porous medium. Because the ink droplets are small and the printing area formed on the surface of the medium is small, the...
