Abstract:
A color shifting pigment flake, comprising:a reflector layer having a top surface, a bottom surface, and at least one side surface; a first dielectric layer over the top surface but not the at least one side surface of the reflector layer; a second dielectric layer over the bottom surface but not the at least one side surface of the reflector layer; and a titanium-containing absorber layer substantially surrounding the first and second dielectric layers and in contact with the at least one side surface of the reflector layer; wherein the pigment flake exhibits a discrete color shift such that the pigment flake 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.
