• High security: The color-changing effect of optical color-changing pigments is difficult to replicate. Its complex optical principle and special preparation process make it difficult for counterfeiters to master, providing reliable anti-counterfeiting protection for important documents such as securities and certificates.

• Intuitive and easy to identify: Without the help of special instruments, the authenticity of items can be quickly identified by simply observing the color change caused by the angle or light change with the naked eye. The public recognition is high, which is convenient for consumers and law enforcement personnel to conduct anti-counterfeiting identification.

• Strong stability: It has good physical and chemical stability. Under normal use and storage conditions, the color change characteristics remain unchanged for a long time, and the anti-counterfeiting effect can be maintained for a long time. It is suitable for various environments and long-term use items.

• Combination of aesthetics and concealment: While realizing the anti-counterfeiting function, it can also add unique visual effects to products or documents to enhance the aesthetics. Moreover, its anti-counterfeiting features are relatively hidden and will only appear under specific observation conditions, which increases the difficulty of counterfeiting.
