Patent ID: 8734908

Claim:
A method for producing a resin-coated metal pigment comprising: an adsorption step of bringing a solution of a phosphate ester component (A) containing phosphate mono- and/or diesters having a radical polymerizable double bond, or a dispersion liquid containing said phosphate ester component (A) dispersed in a solvent into contact with a metal pigment to prepare a phosphate ester adsorbing metal pigment containing a phosphate ester adsorbed on the surface of said metal pigment; a slurry preparation step of preparing a slurry for polymerization obtained by dispersing said phosphate ester adsorbing metal pigment in a solvent for polymerization and dissolving a polymerization component (B) including a monomer and/or an oligomer having at least one polymerizable double bond in said solvent for polymerization; and a coating step of polymerizing said polymerization component (B) to form a resin coating layer on the surface of said phosphate ester adsorbing metal pigment, wherein said dispersion liquid is obtained by mixing a solution obtained by dissolving said phosphate ester component (A) in a first solvent, with a second solvent, said solvent for polymerization is a solvent having solubility at 25° C. of said phosphate ester component (A) of 10 g or less with respect to 100 g of said solvent, and a phosphorus content per unit surface area of said resin-coated metal pigment is within a range from 0.05 to 1.3 mg/m 2 .
