Abstract
A thermosetting high solid coating composition which is characterized in that said composition consumes less solvents in production, evolves less solvent vapor in use, and consists of: (a) 80 to 60 parts by weight of alkyd resin having a fatty acid content of 10 to 20% by weight, a phenyl group content of 10 to 25% by weight and a dibasic acid ratio and a hydroxyl group equivalent within certain ranges, (b) 20 to 40 parts by weight of melamine resin mainly comprising hexakisalkoxymethylmelamine, (c) if desired, alcohol modified melamine resin replacing not more than one half of said melamine resin (b), (d) 0.05 to 1.00 part by weight of aliphatic or aromatic sulfonic acid or their amine salts, and (e) 70 to 20 parts by weight of solvents at the time of spray coating.
