摘要

black effect pigment, ink, coating, powder coating, printing ink, laser marking pigment, cosmetic formulation, pigment composition or dry preparation, method for preparing black effect pigment, and use of sno2 and / or hydrated sno2 this description is directed to a black effect pigment and a method of forming said pigment. The pigment comprises a laminar substrate coated with sno ~ 2 ~ and / or sO ~ 2 ~ and fe ~ 3 ~ 4 ~ hydrates with an optional coating of metal oxides such as sodium ~ 2 ~, thio ~ 2- , zro ~ 2 ~ and zno ~ 2 ~. The deposition of sno2 and / or sno2 hydrates on the substrate improves adhesion and prepares the substrate surface for the deposition of iron oxides on the laminar surface, especially mica surfaces. While pigment can 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, pigment is especially suitable for applications.
