  • AQUEOUS RESIN COMPOSITION, AQUEOUS COATING COMPOSITION AND COATING METHOD FOR PLASTIC MOLDED ARTICLES
    Publication number: 20090061247
    Abstract: An aqueous resin composition obtained by emulsion polymerization using a polymerizable unsaturated monomer (b) in the presence of an aqueous resin dispersion (A) comprising an acid-modified polyolefin (a), an ether-based solvent and a basic substance. Also, an aqueous coating composition comprising an aqueous resin dispersion (B) obtained by emulsion polymerization of a polymerizable unsaturated monomer (b) in the presence of an aqueous resin dispersion (A) containing an acid-modified polyolefin (a), an ether-based solvent and a basic substance, with resin beads (C), wherein the content of resin beads (C) is 1-30 parts by mass with respect to 100 parts by mass of the total resin solid content of the coating material. The composition has excellent adhesion for plastic bases and allows formation of coated films with excellent water resistance, stain resistance, damage resistance and solvent resistance.
