Abstract
Official abstract text for this publication.
The invention relates to platelet-shaped pearlescent pigments that are coated with at least one mixed inorganic/organic layer for improving their application properties, and of these, particularly their mechanical properties, and to methods for the production thereof and to the use thereof. The said mixed inorganic/organic layer comprises at least one at least partially crosslinked inorganic metal-oxide component and an organic component. The organic component is at least one organic oligomer and/or polymer, which is covalently bonded, at least in part, to the inorganic network via network formers, wherein the coating comprises at least one mixed inorganic/organic layer, which mixed layer comprises, at least in part, an inorganic network having one or more inorganic oxide component(s) and at least one organic component, the organic component being, at least in part, an organic oligomer and/or polymer covalently bonded, at least in part, to the inorganic network via one or more organic network formers. The invention also relates to a method for the production of such pearlescent pigments.
First claim
Opening claim text (preview).
What is claimed is: 1. Pearlescent pigments comprising a coating and a platelet-shaped transparent substrate that includes a platelet-shaped transparent core comprised of a material selected from a group consisting of mica, talc, sericite, kaolin, SiO 2 , glass, graphite, Al 2 O 3 , and mixtures thereof, wherein the coating comprises at least one mixed inorganic/organic layer, said mixed layer comprising at least in part an inorganic network having one or more inorganic oxide compo…
