Optical chameleon pigmentComposed of optical variable color film fragments with specific spectral characteristics. The optical variable color film is an optical film designed with specific reflection spectral characteristics based on the principle of light interference of multilayer films. It has substances with various refractive indices. Using vacuum coating technology, according to the requirements of a specific film system structure design, the thickness and sequence of each film layer are accurately controlled and deposited on the same carrier in sequence.

Has the following characteristics:

1. The angular异色性 has simple and easily identifiable characteristics, meeting the requirements of public identification.

2. The angular异色性 and metallic texture cannot be replicated by equipment such as high-precision scanners and color copiers.

3.Optical variable pigmentNon-toxic, odorless, pollution-free, stable structure, strong weather resistance, safe and reliable to use.
