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-counterfeiting ink, and discloses an easily identifiable anti-counterfeiting ink and a preparation method thereof. The anti-counterfeiting ink comprises the following components: self-crosslinking cationic silicone acrylic emulsion, epoxy acrylic resin, curcumin, pH regulator and solvent. The anti-counterfeiting identification method of the anti-counterfeiting ink is simple, fast, easy to identify, and has good stability, and can adapt to the actual anti-counterfeiting needs.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting ink, 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 ink 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-tampering inks, nano-inks, intelligent 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, reactive color-changing inks can also be divided into heat-sensitive inks, moisture-sensitive inks and chemical reactive color-changing inks (that is, the anti-counterfeit...
