<P>PROBLEM TO BE SOLVED: To provide an aqueous resin composition which has high weatherability and exhibits good stain resistance and storage stability even in the form of a one-component type coating material, and further exhibits adhesion with a substrate. <P>SOLUTION: The resin composition for an aqueous coating material contains (I) a synthetic resin emulsion, (II) a silicon compound represented by general formula (1): (R<SP POS="POST">1</SP>O)<SB POS="POST">4-a</SB>SiR<SP POS="POST">2</SP><SB POS="POST">a</SB>, and/or its partially hydrolyzed condensate and/or its modified substance, (III) a specific silane coupling agent, (IV) a photo-sensitizer and/or (V) a photoacid generator and/or (VI) a photo-base generator. In the general formula (1), R<SP POS="POST">1</SP>are the same or different and each represent 1-10C alkyl group, 6-10C aryl group or a 7-10C aralkyl group; R<SP POS="POST">2</SP>are the same or different and each represent 1-10C alkyl group, 6-10C aryl group or a 7-10C aralkyl group; and a is an integer of 0-2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
