PROBLEM TO BE SOLVED: To provide a top-coating composition which can form a coating film excellent in stain resistance and impact resistance and also excellent in appearance, weathering resistance, water resistance, solvent resistance, chemical resistance, and adhesion, and to provide a finish-coating method and a finish-coated article. SOLUTION: The top-coating composition comprises 30-90 pts.mass (a) lactone-modified acrylic polyol resin obtained by adding 10-200 pts.mass lactone compound to 100 pts.mass acrylic polyol resin having a hydroxyl value of 75-250 mgKOH/g and an acid value of 0.5-50 mgKOH/g and subjecting the mixture to a ring opening addition reaction in the absence of a catalyst, 10-70 pts.mass (b) polyisocyanate compound, and 0.01-20 pts.mass (c) condensate of a partial hydrolyzate of a specified alkoxysilane as the essential components and (e) additives as optional components. The finish-coating method comprises using the top-coating composition, and the finish-coated article is obtained by the finish-coating method. COPYRIGHT: (C)2004,JPO
