摘要:
The invention relates to metallic effect pigments with coating, comprising a platelet-shaped substrate, where the coating comprises at least one hybrid inorganic/organic layer, the hybrid layer having at least partly an inorganic network that has one or more inorganic oxide components, and having at least one organic component, the organic component being at least partly an organic oligomer and/or polymer which is covalently bonded at least partly to the inorganic network via one or more organic network formers. The invention further relates to a method of producing these metallic effect pigments, and to their use.
