PROBLEM TO BE SOLVED: To provide a resin composition for a water-based coating material exhibiting excellent stain resistance and storage stability. SOLUTION: The resin composition for a water-based coating material comprises (I) an acrylic resin emulsion obtained by emulsion polymerization using an anionic surfactant being an alkali metal salt and (II) an emulsion of a silicone compound obtained by emulsifying a silicone compound represented by general formula (1): (R<SP>1</SP>O)<SB>4-a</SB>SiR<SP>2</SP><SB>a</SB>(wherein R<SP>1</SP>s are the same or different and are each 1-10C alkyl, 6-10C aryl or 7-10C aralkyl; R<SP>2</SP>s are the same or different and are each 1-10C alkyl, 6-10C aryl, 7-10C aralkyl or 1-10C alkoxy; and a is an integer of 0-2) and/or its partial hydrolysis-condensation product using an anionic surfactant being an alkali metal salt.
