  • Patent number: 9815970
    Abstract: A high chroma effect pigment includes a platelet substrate and an optical coating formed on the platelet substrate. The optical coating includes a first high refractive index layer, a second high refractive index layer on the first high refractive index layer, and a diffused third material having a range of diffusion between 100% to partial diffusion in the first high refractive index layer, the second high refractive index layer, or both the first and the second high refractive index layers. The first and second high refractive index layers independently have a refractive index of about >1.65. The diffused third material is SiO2 or a metal oxide is different than the first and second high refractive index layers.

  • Patent number: 8728502
    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 SnO2 and/or SnO2 hydrates and Fe3O4 with an optional coating of metal oxides such as SiO2, TiO2, ZrO2 and ZnO2. The deposition of the SnO2 and/or SnO2 hydrates 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.
