DD9819 Chameleon (Green, Blue, Purple)

Optical chameleon pigmentComposed of fragments of optical color-changing films with specific spectral characteristics. The optical color-changing film is an optical film with specific reflection spectral characteristics designed 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 successively on the same carrier.

Has the following characteristics:

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

2. The angular异色ity 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
