Colored metallic pigment, method for the production of same and products containing same

A method for the production of a primary colored metallic pigment, comprising

• a) agitating 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, and a metallic pigment in an organic solvent, for from 30 minutes to 5 hours,
• b) heating up the mixture from about 50.degree. C. to about 150.degree. C. and filtering the mixture to obtain a cake,
• c) cooling down the temperature of the mixture to room temperature and mixing the cake and a coloring pigment by kneading or agitating the cake and the coloring pigment in an organic solvent, and
• d) removing excessive organic solvent.

• d) adding a radical polymerizable unsaturated carboxylic acid to the mixture while dispersing and agitating the mixture in an organic solvent,
• e) adding a monomer having at least three radical polymerizable unsaturated double bonds and a polymerization initiator to the mixture and polymerizing the resulting mixture, and
• f) removing excessive organic solvent.
