Summary: | The invention relates to a pearl luster pigment which may possess a first, inner layer, consisting of a platelet-shaped substrate, a second layer, comprising one or more metal oxides, the first and second layers forming a calcined base pigment, a third layer, comprising the corresponding uncalcined oxide, hydroxide or oxide hydrate of the oxide of the second layer, a fourth layer, comprising oxides, hydroxides and/or oxide hydrates of silicon or aluminum, a fifth layer, comprising oxides, hydroxides and/or oxide hydrates of silicon, aluminum, zirconium and/or cerium, this layer differing from the fourth layer, and a sixth layer, comprising one or more organofunctional coupling reagents. The present invention relates to also a preparation process, and the use of the pigments in paints, inks, plastics, coatings and cosmetics. |
