Abstract
This disclosure is directed to a black effect pigment and a method of forming said pigment. The pigment comprises a platy substrate coated with SnOand/or SnOhydrates and FeOwith an optional coating of metal oxides such as SiO, TiO, ZrOand ZnO. The deposition of the SnOand/or SnOhydrates onto the substrate improves the adhesion and prepares the substrate surface for deposition of the iron oxides onto the platy surface, especially mica surfaces. While the pigment may be used in such applications as coating, powder coating, printing ink, plastic, ceramic material, glass, cosmetic formulation, laser marking pigment, pigment composition or dry preparation, the pigment is especially suitable for cosmetic applications.
