Abstract:
The present invention relates to wet-chemically oxidized aluminium effect pigments which comprise at least one oxide metal oxide layer which is different from aluminium oxide and an enveloping organic polymer layer, the weight ratio of the oxide metal oxide layer which is different from aluminium oxide to the wet-chemically produced aluminium oxide layer ranging from 1:1 to 1:40. The present invention further relates to a method for producing the aforementioned pigments and to the use thereof.
Abstract:
A coated platelet that includes a robust polymer coating that has substantially uniform structures, a method for producing the coated platelet and a system that includes the coated platelet are described. The disclosed method involves immobilizing initiator molecules onto the surfaces of the platelet by using surface coupling groups and polymerization from initiating sites of the initiator anchored on the surface of the platelet The disclosed method allow s uniform growth of the polymer chains so as to produce robust coated platelets with a smooth coated surface. The disclosed system includes only the disclosed coated platelet and a solvent and eliminates the need to add polymer resins separate from the resins that are covalently attached to the platelet.

The invention also relates to a method for producing said pigments as well as the use thereof.
Abstract:
The invention relates to metal effect pigments comprising a coating and a lamellar substrate. The coating is provided with at least one mixed inorganic/organic layer which contains, at least in part, an inorganic network encompassing one or several inorganic oxide components, and at least one organic component which at least partly represents an organic oligomer and/or polymer that is covalently bonded at least in part to the inorganic network via one or several organic network formers. The invention also relates to a method for producing said metal effect pigments and the use thereof.
Abstract:
The invention relates to metal pigments comprising a coating. The coating surrounds the metal pigments and comprises cross-linkable oligomer and/or polymer binding agent(s) which are chemically cross-linkable and/or active under the influence of heat, IR radiation, UV radiation and/or electron radiation. The coated metal pigments are embodied in the form of powder, which has a particle size d50 of less than 190 µm, and are resistant to corrosion after hardening in a coating powder. The invention further relates to a coating composition, to a method for the production of the coated metal pigments, in addition to the use thereof.
Abstract:
The invention is directed to a plate-like PVD aluminum pigment with a protective encapsulation, wherein said protective encapsulation comprises a) a continuous encapsulating silicon oxide containing coating (a), wherein said silicon oxide containing coating comprises at least 60 wt.-% silicon oxide, based on the total weight of said silicon oxide containing coating, and b) a layer (b) of metal oxide, wherein said metal oxide is selected from the group consisting of molybdenum oxide, molybdenum hydroxide, molybdenum oxide hydrate, tungsten oxide, tungsten hydroxide, tungsten oxide hydrate and mixtures thereof, and c) optionally an outer organic-chemical modification layer. The invention is further directed to method for producing the plate-like metal pigment as well as the use thereof.
