Abstract:
The present invention relates to interference pigments based on multicoated flake-form substrates which have on the surface of the substrate a layer sequence comprising (A0) optionally a high-refractive-index coating consisting of a layer of TiO2, (A) a high-refractive-index coating consisting of a mixture of TiO2 and Fe2O3, which may optionally be doped with one or more further oxides, (B) a high-refractive-index layer consisting of SnO2, (C) a high-refractive-index coating which absorbs in the visible wavelength region, and optionally (D) an outer protective layer, and to the use thereof, in particular in paints, coatings, industrial coatings, automobile paints, automotive refinish paints, coil coating, powder coatings, printing inks, plastics, pigment pastes, pigment preparations and in dry preparations, such as, for example, granules.
