Goniochromatische Glanzpigmente mit metallsulfidhaltiger Beschichtung

摘要

Goniochromatic bright pigments based on plate-like metallic substrates coated several times have at least one group of layers, namely (A) a layer substantially made of silicium oxide, silicium oxide hydrate, aluminium oxide and/or aluminium oxide hydrate, and (B) a non-selectively absorbing, metal sulphide-containing layer that is at least partially transparent to visible light, and optionally (C) an additional outer layer substantially made of colourless or selectively absorbing metal oxide. Also disclosed is the production and use of said pigments for colouring lacquers, printing or other inks, plastics, glass, ceramic products and decorative cosmetic compositions.
