PURPOSE:To obtain a finishing method of a coated film which is one-pack type and excellent in the low-temp. curing characteristics and has the excellent physical characteristics of the coated film in the low-temp. atmosphere by using a paint consisting essentially of amino resin and thermosetting acrylic resin having the specified glass transition temp. CONSTITUTION:In a finishing method of a coated film due to the one coat/bake finishing, both amino resin and thermosetting acrylic resin C having <=0 deg.C glass transition temp. are made to an essential component as a paint. As a monomer component constituting the resin C, 5-80wt% acrylic acid alkyl ester is contained for the total quantity of the monomer component and alpha,beta-unsaturated carboxylic acid hydroxylalkyl and alpha,beta-unsaturated carboxylic acid, etc., are contained so that hydroxyl group value and acid value of the obtained resin C are regulated to (35-90) and (6-40) respectively. The paint contg. one kind selected from a group consisting of dicarboxylic acid and its monoalkyl ester is used.
