PROBLEM TO BE SOLVED: To provide a paint for precoated metal, which has excellent weather resistance and is less expensive compared with a case where a fluorocarbon resin is used, and to provide a composition used for exhibiting the effects thereof.SOLUTION: The composition (A) used in the paint for precoated metal contains a polyol component (a), a crosslinking agent (b), and a compound (c) containing two or more radically-polymerizable unsaturated groups in one molecule. A polyester polyol (a1) accounts for at least 50 wt.% of the polyol component (a). The crosslinking agent (b) is preferably a blocked polyisocyanate (b1) and/or an amino resin (b2). |
