PCT No. PCT/JP96/01522 Sec. 371 Date Apr. 21, 1997 Sec. 102(e) Date Apr. 21, 1997 PCT Filed Jun. 5, 1996 PCT Pub. No. WO96/39454 PCT Pub. Date Dec. 12, 1996A thermosetting composition which comprises (A) an epoxy group-containing modified polyester polymer comprising a structural moiety of (a) a carboxyl group-containing polyester resin having a number average molecular weight of 1,500 to 50,000 and a resin acid value of 2 to 30 mgKOH/g and a structural moiety of a polymer of (b) an epoxy group-containing vinyl monomer, the carboxyl groups and a part of the epoxy groups being bonded in an equivalent ratio of the carboxyl groups in the component (a) to the epoxy groups in the polymer of the component (b) of 0.1 or less, and having an epoxy equivalent weight of 200 to 2,000 g/mol, and (B) a compound having two or more functional groups which are blocked by a vinyl ether, vinyl thioether or heterocyclic group carrying oxygen or sulfur as the heteroatom and having a double bond of the vinyl type. The composition can give cured articles excellent in hardness, chemical resistance, stain resistance, processability, impact resistance, elasticity and weathering resistance and has a good storage stability.
