Water-based coating composition curable with actinic energy ray, coated metallic material with cured film of the composition, production process, and method of bonding coated metallic material

摘要

A radiation curable aqueous coating composition comprises an aqueous resin having a chemically bonded phosphate group and an ethylenic unsaturated double bond, and/or a phosphate compound having an ethylenic unsaturated double bond and an aqueous resin having an ethylenic unsaturated double bond, which has high solvent resistance and adhesion to the surface of the metal material.
