| 摘要 |
Luster pigments comprising coated, plateletlike, silicatic substrates wherein the coating comprises a layer consisting essentially of carbon and aluminum oxide, chromium oxide, cerium oxide, zirconium oxide, antimony oxide or mixtures thereof, are obtainable by applying carbon-containing compounds of the metals aluminum, chromium, cerium, zirconium, antimony or mixtures thereof with or without further carbon-containing compounds of the molecular formula (CH2O)n, where n is from 1 to 6 for one monomeric unit, to the substrate particles and then thermally decomposing the carbon-containing compounds on the surface of the substrate particles under oxygen-excluding conditions.
