WATER-BASED COATING RESIN COMPOSITION AND PROCESS FOR FORMING COATING FILM EXCELLENT IN STAIN RESISTANCE

摘要

A resin composition suitable as water-based paints which comprises 100 parts by weight of an emulsion of a polymer obtained by copolymerizing a silyl group-containing vinyl monomer with other vinyl monomers, 1 to 70 parts by weight of a silicon compound and/or its partial hydrolysis condensation product and/or a silicon compound having at least one amino group and/or its derivative and at least one hydrolyzable silyl group in one molecule, and 0 to 20 parts by weight of a curing catalyst. When the resin composition is coated onto materials to be coated, coating films having an excellent stain resistance in addition to excellent weatherability and durability are formed on the sufaces of the materials to be coated.
