A curable composition for paint containing:(A) 95 to 5 parts by weight of a vinyl copolymer having at least one specific hydrolyzable silyl group and at least one specific alcoholic hydroxyl group existing at an end of the main chain and/or in a side chain thereof in one molecule, in which the main chain contains substantially a vinyl copolymer chain and the alcoholic hydroxyl equivalent is from 180 to 2000 g/mol;(B) 5 to 95 parts by weight of a vinyl copolymer having at least one specific hydrolyzable silyl group at an end of the main chain and/or in a side chain thereof in one molecule and having no alcoholic hydroxyl group in the same molecule, in which the main chain contains substantially a vinyl copolymer chain; and(C) 0.001 to 10 parts by weight of a curing catalyst per 100 parts by weight of the total resin solids content.This curable composition for paint has well-balanced properties of good acid resistance, water resistance, scratch resistance, weathering resistance, and so forth.
