Carbon black in effect pigments
The present application is directed to combination effect pigments comprising an effect pigment and carbon black, wherein the carbon black is adherently deposited on the effect pigment interposed within the substrate and at least one subsequent layer of the effect pigment. This structure of the combination effect pigment results in advantageous non-staining properties of the pigment and maximizes color effects of the carbon black.
Pigment powders
Disclosed are pigment powders containing only coated BiOCl flakes, which flakes area) BiOCl flakes having a coating containing yellow iron oxide Fe.sub.2O.sub.3*xH.sub.2O, optionally a colorant, optionally an adjuvant, and optionally SiO.sub.2, b) BiOCl flakes having a coating containing SiO.sub.2, optionally a colorant, and optionally an adjuvant, c) BiOCl flakes having a coating containing a colorant, SiO.sub.2, optionally yellow iron oxide Fe.sub.2O.sub.3*xH.sub.2O, and optionally an adjuvant, or d) BiOCl flakes having a coating containing Fe.sub.3O.sub.4 and optionally SiO.sub.2, to a process for the preparation of the pigment powders, and to the use thereof especially in cosmetic formulations.
