Abstract:
The present invention relates to pigments based on multicoated flake-form substrates which are distinguished by the fact that at least 8 layers [layers (A)-(H)] are on the substrate, where an SiO2 layer (=layer A) is located directly on the surface of the substrate, and to the use thereof, inter alia, in paints, surface coatings, automobile paints, powder coatings, printing inks, security printing inks, plastics, ceramic materials, glasses, paper, in toners for electrophotographic printing processes, in seed, in greenhouse sheeting and tarpaulins, as absorbers in the laser marking of paper and plastics, and in cosmetic formulations, for the preparation of pigment pastes with water, organic and/or aqueous solvents, for the preparation of pigment compositions and dry preparations.
