<p>An unsaturated polyester (i) having a weight-average molecular weight (Mw) of 1,000 to 100,000 and at least two carbon-carbon unsaturated bonds in the molecule, which is prepared by esterifying a polyester polyol (a) prepared by polycondensing a polycarboxylic acid containing a polymerized fatty acid and/or a polymerized fatty acid ester with a polyhydric alcohol with an unsaturated carboxylic acid (b); and an unsaturated (poly)urethane having an Mw of 1,000 to 100,000 and at least two carbon-carbon unsaturated bonds in the molecule, which is prepared by reacting the polyester polyol (a) with a polyisocyanate (d) and a polymerizable compound (e) having an active hydrogen atom and a carbon-carbon unsatured bond. The above unsaturated polyester and (poly)urethane give products of curing excellent in adhesion, heat resistance, water resistance, and flexibility.</p> |
