Abstract
A resin composition comprising (I) at least one compound selected from the group consisting of hydroxyl-containing unsaturated polyesters, reaction products of polyepoxides and ethylenically unsaturated carboxylic acids and .beta.-polymers of diallyl phthalate (II) at least one monomer copolymerizable with said compound (I), which is selected from the group consisting of ethylenically unsaturated monomers and allylic unsaturated monomers, (III) a catalyst capable of polymerizing (I) and (II), (IV) at least one compound containing the oxirane ring, (V) a curing agent (excluding acid anhydrides, acids and amine compounds) capable of curing said compound (IV), and (VI) a catalyst capable of promoting the curing of (IV) by (V). A preferable composition further contains (VII) a polyisocyanate compound and (VIII) a promoter for the reaction between isocyanate group and hydroxyl group. The composition may contain fibrous reinforcing agents.
