Zusammenfassung:PROBLEM TO BE SOLVED: To enable a high-speed baking of a coating film formed on an aluminum material and thus enable a high-speed production of a coated aluminum material excellent in coated appearance. SOLUTION: In this coating material for baking finish comprising a resin component, a solvent mixture, and unavoidable impurities, the contents of solvents constituting the solvent mixture are each 40wt.% or lower; the ratio of (diluent %)/(true solvent %) of each solvent is 1 or lower; and the differences in b.p. among solvents each contained in a content of 10wt.% or higher are within 7 deg.C. High-speed production of a coated aluminum material excellent in coated appearance is realized by continuously applying the coating materiel to an aluminum material in a coiled state followed by baking.
