    Abstract: PROBLEM TO BE SOLVED: To improve coating stability, flatting appearance, weatherability and gloss stability of flatting anion electrodeposition coating by a resin composition comprising an acrylic resin containing a carboxyl group, a specific organoalkoxysilane compound and an aluminum chelate compound. SOLUTION: In producing an acrylic resin, a polymerizable unsaturated carboxylic acid, a hydroxyl group-containing unsaturated monomer according to needs, an alkoxysilane group-containing unsaturated monomer or an epoxy group-containing unsaturated monomer are copolymerized to obtain an acrylic resin having a carboxyl group and a hydroxyl group or an epoxy group at a side chain or a termination of the copolymer. The acrylic resin has a hydroxyl value of 20-150 mgKOH/g, preferably 30-100 mgKOH/g and number average molecular weight of 2,000-70,000, preferably 4,000-50,000. A resin composition is obtained by compounding 100 pts.wt. of the acrylic resin, and 0.05-100 pts.wt. of an organoalkoxysilane compound having a glycidyl group and a hydrolyzable alkoxy silane group and 0.01-10 pts.wt. of an aluminum chelate compound.
