摘要

An unsaturated polyester (i) having a weight-average molecular weight (Mw) of 1,000-100,000 and at least two carbon-carbon unsaturated bonds in the molecule thereof obtained by esterifying an unsaturated carboxylic acid (b) with a polyester-polyol (a) obtained by subjecting a polybasic carboxylic acid containing polymerized fatty acid and/or polymerize fatty acid ester to polycondensation with a polyhydric alcohol; and an unsaturated (poly)urethane having Mw of 1,000-100,000 and at least two carbon-carbon unsaturated bonds in molecule obtained by reacting said polyester-polyol (a), polyisocyanate (d) and compound (e) having active hydrogen and polymerizable carbon-carbon unsaturated bond. Said unsaturated polyester and unsaturated (poly)urethane exhibit excellent adhesive property, heat resistance, water resistance and flexibility after being cured.
