A heat-resistant resin composition, comprising (A) 30 to 95% by weight of at least oen unsaturated ester compound selected from the group consisting of (I) unsaturated ester compounds represented by the formula I: <IMAGE> (I) wherein R1s independently stand for one member selected from the class consisting of <IMAGE> +TR <IMAGE> wherein R3 and R4 independently stand for a hydrogen atom or a methyl group, and a hydrogen atom, and at least one R1 stands for <IMAGE> wherein R3 and R4 independently stand for a hydrogen atom or a methyl group, and R2s independently stand for an atom or an organic group selected from the class consisting of a hydrogen atom, halogen atoms, a methoxy group, and alkyl groups of 1 to 5 carbon atoms, and m stands for 0 or an integer in the range of 1 to 10, and (II) unsaturated ester compounds represented by the formula II; <IMAGE> (II) wherein R5s independently stand for one member selected from the class consisting of <IMAGE> +TR <IMAGE> wherein R3 and R4 independently stand for a hydrogen atom or a methyl group, and a hydrogen atom, at least one R5 stands for <IMAGE> wherein R3 and R4 independently stand for a hydrogen atom or a methyl group, R6s independently stand for an atom or an organic group selected from the class consisting of a hydrogen atom, halogen atoms, a methoxy group, and alkyl groups of 1 to 5 carbon atoms, n stands for 0 or an integer in the range of 1 to 10, and X stands for a divalent organic group selected from the class consisting of <IMAGE> where n is 0 or X's independently stand for a divalent organic group selected from the class consisting of <IMAGE> wherein n is an integer in the range of 1 to 10, (B) 70 to 5% by weight of a polymerizable crosslinking agent, and (C) 0.,5 to 15 parts by weight, based on 100 parts by weight of a vinyl ester resin composed of (A) said unsaturated ester compound and (B) said polymerizable crosslinking agent, of a butadiene-acrylonitrile copolymer having at least one (meth)acryloyl group in the molecular unit thereof.
