Metal effect pigments with inorganic / organic mixed layer, a method for the production of such metal effect pigments and their use

摘要

The present invention relates to metal effect pigments with a coating comprising a platelet-like substrate, wherein the coating at least one inorganic / organic mixed layer, wherein the mixed layer is at least in part an inorganic network, the one or more inorganic oxide component (n), and at least one organic component, wherein the organic component, at least partially an organic oligomer and / or polymer, which has at least partially with the inorganic network via one or more organic network former is covalently coupled. The present invention also relates to a process for the production of these metal effect pigments as well as their use.
