PURPOSE:To provide the titled paint which is a baking type, has excellent adhesion and storage stability and can form a coating film having a long-term corrosionproofing effect, consisting of a specified thermosetting acrylic resin, an amino resin, an epoxy resin and a blocked isocyanate. CONSTITUTION:0.5-8pts.wt. amino resin (e.g. n-butylated melamine resin), 0.5- 8pts.wt. epoxy resin having an epoxy equivalent of 150-2,000, 0.5-8pts.wt. blocked polyisocyanate (e.g. hexamethylene diisocyanate) and optionally additives such as org. solvent, color pigment, extender pigment (e.g. silica), etc. are mixed with 100pts.wt. thermosetting acrylic resin contg. hydroxyl and carboxyl groups and having a number-average MW of 3,000-30,000 and a hydroxyl value of 30- 150mgKOH/g to obtain the titled paint.
