Problems solved by technology

[0003] Among them, the reaction color-changing ink can also be divided into heat-sensitive ink, moisture-sensitive ink and chemical reaction color-changing ink (that is, the added anti-counterfeiting material changes color when encountering acid and alkaline substances), but this type of ink usually has poor stability and short service life. Detection is also inconvenient, which limits the application and development of this type of ink

Abstract

The invention belongs to the technical field of anti-forgery ink, and discloses easy-to-recognize anti-forgery ink and a preparation method thereof. The anti-forgery ink comprises the following components: a self-crosslinking cationic silicone acrylic emulsion, epoxy acrylic resin, curcumine, a pH regulator and a solvent. The anti-counterfeiting identification method of the anti-counterfeiting ink is simple, quick and easy to identify, has better stability and can meet the actual anti-counterfeiting requirement.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting inks, in particular to an easily identifiable anti-counterfeiting ink and a preparation method thereof. Background technique [0002] Anti-counterfeiting ink is to add other materials with special functions on the basis of conventional inks to play an anti-counterfeiting role. Anti-counterfeiting ink has become an important part of anti-counterfeiting technology. At this stage, anti-counterfeiting inks mainly include fluorescent inks, reactive color-changing inks, anti-alteration inks, nano-inks, smart anti-counterfeiting inks and infrared inks, etc. Each anti-counterfeiting ink has its own advantages and disadvantages, and there is still room for improvement. Ongoing research and refinement. [0003] Among them, the reaction color-changing ink can also be divided into heat-sensitive ink, moisture-sensitive ink and chemical reaction color-changing ink (that is, the added anti-counterf...
