PLATE-LIKE PVD ALUMINUM PIGMENT WITH A PROTECTIVE ENCAPSULATION AND METHOD FOR MANUFACTURING A PLATE-LIKE PVD ALUMINIUM PIGMENT WITH A PROTECTIVE ENCAPSULATION

摘要

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.
