Heat-curable coating composition

A heat-curable coating composition comprising as a binder (A) an oil-free polyester in which at least 30 mole % of the acid component consists of a saturated alicyclic polybasic acid, said polyester having a composition on or within the four sides of a tetragon defined by four points of (0.8, 60), (...

Summary:A heat-curable coating composition comprising as a binder (A) an oil-free polyester in which at least 30 mole % of the acid component consists of a saturated alicyclic polybasic acid, said polyester having a composition on or within the four sides of a tetragon defined by four points of (0.8, 60), (0.8, 100), (1.00, 70) and (1.00, 100), on coordinates in which the abscissa represents the molar ratio of the polybasic acids to the polyhydric alcohols (dibasic acid ratio) and the ordinate represents the proportion in mole % of a glycol having at least 3 carbon atoms in the polyhydric alcohols, (B) an alkyd resin having an oil length of 15 to 50% and a hydroxyl value of 40 to 200, (C) a hydroxyl-containing acrylic resin having a hydroxyl value of 20 to 200 and a number average molecular weight of 1,000 to 30,000, and (D) a crosslinking agent.
