Optically variable materials have a distinct color change effect and can be visually distinguished at different angles, making them easily recognizable. They possess specific spectral characteristics, such as a five-layer optical interference inorganic material and multi-layer optical interference inorganic material with ultra-fine micrometer-sized particles.

Production process: The production process of optically variable multilayer inorganic materials is complex and requires special coating equipment, involving high-end technologies such as inorganic fine chemical engineering, vacuum coating technology, optical technology, and nano-vacuum airflow pulverization.

They are widely used in currency, passports, tax receipts, securities, certificates, as well as high-value luxury goods, pharmaceuticals, cigarette packaging, tea packaging, and various anti-counterfeit marks. They are also used in the beauty and nail industry, high-end coatings, and automotive spray painting industry.

This fully reflects the social values of safe manufacturing processes, safe consumer use, and anti-counterfeiting security, and expresses the company's mission of meeting customers' unique value requirements.
