MULTILAYER MAGNETIC REFLECTING PIGMENT FLAKES AND FOILS

摘要

A color shifting interference structure is provided. The color shifting interference structure comprises: a magnetic layer, a reflector layer, a dielectric layer over the reflector layer, and an absorber layer over the dielectric layer. The interference structure exhibits a color shift such that the interference structure has a first color at a first angle of incident light or viewing and a second color different from the first color at a second angle of incident light or viewing. The interference structure further comprises an insulator layer over the magnetic layer and the reflector layer is disposed over the insulator layer. The insulator layer has a thickness for preventing corrosion of the interference structure.
