DK36 series traditional optical color changing pigment
The five-layer metal medium symmetric thin film structure design forms an optical interference multilayer film with a total reflection mirror effect and a specific color change characteristic. based on the inherent flop effect of interference, the reflection spectrum changes with the angle of observation of the human eye. Changes, resulting in special color change effects, are widely used in the field of security printing.
