    Abstract: PROBLEM TO BE SOLVED: To obtain both a coating material which is prepared by using a specific excellent acrylic resin having balanced various performances as a coating binder and has excellent adhesivity to a hardly adherent material, especially a hardly adherent metal such as a magnesium alloy, an aluminum alloy, stainless steel, and to provide a coated article. SOLUTION: This composition for a coating material comprises an acrylic emulsion (A) obtained by subjecting a hydroxy group-containing unsaturated monomer (a), an epoxy group-containing unsaturated monomer (b) and another unsaturated monomer to emulsion copolymerization and an aqueous acrylic resin (B) containing a tertiary amino group and carboxyl group at the side chain. The acrylic emulsion (A) is mixed with the aqueous acrylic resin (B) in the weight ratio of 1/99 to 99/1.

    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.
