High solid coating composition

PURPOSE: To obtain the subject composition excellent in a low temperature curing property consisting of an allyl-ether-functional unsaturated polyester- urethane obtained from a specific functional unsaturated polyester, diisocyanate and allyl-ether-functional active hydrogen-containing substance. CONSTITUTION: The objective composition comprises (A) a linear acid- or hydroxyl group-functional unsaturated polyester, (B) diisocyanate such as isophorone diisocyanate and (C) an allyl-ether-functional unsaturated polyester-urethane resin composition obtained from an allyl-ether-functional active hydrogen- containing substance such as trimethylolpropane triallyl ether. the component A is preferably a reaction product of (i) an acid-functional substance consisting of diacid and/or acid anhydride with (ii) a hydroxyl group-functional substance consisting of a diol such as 1, 6 hexanediol.
