ABSTRACT:
A collection of color-shifting interference thin film platelets of high chroma characterized in that the platelets are comprised of a metal reflecting layer having first and second surfaces and a multilayer interference thin film structure disposed on both surfaces of the metal reflecting layer. The multilayer interference thin film structure comprises a pair of layers consisting of a dielectric layer and a semi-opaque metal layer with the dielectric layer being directly adjacent to a surface of the metal reflecting layer. The layers of the multilayer interference thin film structure lie in parallel planes. Each platelet has an aspect ratio of at least 2:1, respectively, for surfaces parallel to the planes of layers and surfaces perpendicular to the planes of the layers. The platelets have a maximum dimension on any surface ranging from approximately 2-200 microns.
