Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a curable coating film capable of manifesting excellent curability, adhesion, mechanical characteristics and weather stability and useful for surface coating of a plastic by using an oligomeric condensation product of a specific polycarboxylic acid with an acrylic or a methacrylic ester. SOLUTION: This curable coating film contains (A) an oligomeric condensation product of (A1 ) a compound represented by formula I [R1 is H or methyl; A is a 3-15C aliphatic trivalent residue which contains 0-5 ether bonds (and may contain OH) (e.g. 2,2,2-trimethylolethyl methacrylate) with (A2 ) a compound represented by formula II [Ar is benzene ring or naphthalene ring; (m) is 0-2; (n) is 1 or 2] (e.g. trimellitic anhydride). The oligomeric condensation product having 300-10,000 Da molecular weight is preferably used as the component A in the curable coating film.
