The present invention has its objects to provide a curable composition for top coating which has an excellent stain resistance, adhesiveness, solvent resistance and impact resistance. The present invention relates to a curable composition for top coating which comprises an acrylic copolymer (A) containing a reactive silyl group bound to a carbon atom as represented by the general formula (1)(wherein R1 represents a hydrogen atom or an alkyl group containing 1 to 10 carbon atoms, R2 represents a hydrogen atom or a univalent hydrocarbon group selected from among alkyl groups containing 1 to 10 carbon atoms, aryl groups and aralkyl groups and a represents an integer of 0 to 2), together with a hydroxyl group; 2 to 70 parts by weight, per 100 parts by weight of acrylic copolymer (A), of a silicon compound represented by the general formula (2)(wherein R3 represents a univalent hydrocarbon group selected from among alkyl groups containing 1 to 10 carbon atoms, aryl groups and aralkyl groups, R4 represents a univalent hydrocarbon group selected from among alkyl groups containing 1 to 10 carbon atoms, aryl groups and aralkyl groups and b represents 0 or 1), and/or a partial hydrolyzate condensate (B) thereof; and 0.1 to 50 parts by weight of a compound (C) containing two or more isocyanate groups which serves as a crosslinking agent.
