Invisible anti-counterfeiting printing ink and its anti-counterfeiting membrane

Abstract

For anti-counterfeiting requirement in daily life and work, the current anti-counterfeiting technologies comprise a laser holographic label, a two-dimensional code for counterfeiting resisting, and anti-counterfeiting printing ink printing, wherein, the making cost of a laser holographic label is high, and the two-dimensional code for anti-counterfeiting is easily counterfeited and imitated. The current anti-counterfeiting printing ink is visible under ultraviolet light or infrared light, the invention provides an invisible anti-counterfeiting printing ink, the invisible anti-counterfeiting printing ink is invisible under ultraviolet light or infrared light, has the characteristic of counterfeiting resistance, channeling prevention, good traceability and high price ratio, can substitute for current ultraviolet light or infrared light anti-counterfeiting printing inks, and is the sixth-generation label-free anti-counterfeiting technology.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting materials, in particular to an invisible anti-counterfeiting ink and an anti-counterfeiting film. Background technique [0002] In order to meet the needs of anti-counterfeiting in daily life and work, the existing anti-counterfeiting technologies include laser holographic marking, two-dimensional code anti-counterfeiting, anti-counterfeiting ink printing, etc. Valuable documents in the prior art, such as multi-part bills, certificates, passbooks, documents, etc., are basically in a single format. It can highlight the anti-counterfeiting features from the senses. In actual use, various anti-counterfeiting applications play a relatively weak role in preventing risks. Especially in the financial industry, the perspective of various internal risk prevention is a blind spot, and internal employee cases in the financial industry are prone to occur. [0003] Among them, the production cost ...

Valuable documents in the prior art, such as multi-part bills, certificates, passbooks, documents, etc., are basically in a single format. It can highlight the anti-counterfeiting features from the senses. In actual use, various anti-counterfeiting applications play a relatively weak role in preventing risks. Especially in the financial industry, the perspective of various internal risk prevention is a blind spot, and internal employee cases in the financial industry are prone to occur

[0003] Among them, the production cost of laser holographic marks is high, and the anti-counterfeiting of two-dimensional codes is easy to be imitated by counterfeiters
