Displays color under natural light and instantly becomes colorless upon infrared scanning; offers covert, hard-to-counterfeit security features; and ensures strong adhesion across various printing substrates.

This infrared-disappearing anti-counterfeiting ink displays clear, colored graphics under natural light, yet the pattern completely vanishes when scanned with a dedicated infrared detector; it offers a high level of optical security and is extremely difficult to counterfeit. Compatible with screen, offset, and flexographic printing, it features excellent adhesion, resistance to friction and light fading, and customizable colors; it is suitable for packaging substrates such as paper, plastic film, and aluminum foil. Unlike standard infrared invisible inks, its visible background color does not compromise packaging design. It is widely used for anti-counterfeiting and traceability in sectors such as tobacco, alcohol, pharmaceuticals, official documents, and security papers, offering convenient verification and full environmental compliance (free from hazardous substances).
