PURPOSE:To provide the titled baking-type composition for external panel of preferably household appliance, containing a carboxyl-containing resin, a homopolymer resin produced by the polymerization of a specific monomer and a curing agent at specific ratios and giving a coating film having improved water-resistance. CONSTITUTION:The objective composition contains (A) a resin having carboxyl group (preferably acrylic resin or alkyd resin), (B) is homopolymer resin produced by polymerizing a polymerizable monomer having at least a glycidyl group (preferably an unsaturated carboxylic acid glycidyl ester) and (C) a curing agent consisting of an amino resin. The amount of the glycidyl group in the component B is 1/2-5mol per 1mol of the carboxyl group in the component A. The amount of the residual carboxyl group in the baked and cured product is preferably <=2mgKOH/g based on the component A in terms of acid value.
