Abstract

Abstract A colored metallic pigment comprising a metallic pigment, a coloring pigment, and a thermally polymerized carboxylic acid having at least one double bond and at least two carboxylic groups prepared by the thermal polymerization of at least one double bond-containing carboxylic acid, the coloring pigment being chemically adsorbed on the surface of the metallic pigment via the thermally polymerized carboxylic acid. The colored metallic pigment may be coated with a polymer composed of a radical polymerizable unsaturated carboxylic acid and a monomer having at least three radical polymerizable double bond. A bright paint, bright ink and bright plastics which contain the colored metallic pigment are also disclosed.
