To obtain a rubber-modified thermosetting resin composition excellent in the balance of impact resistance with flexibility.
This rubber-modified thermosetting resin composition consists mainly of (A) 30-99 pts.wt. of a thermosetting resin an d(B) 70-1 pts.wt. of a rubber-reinforced resin produced by polymerizing one or more vinylic monomer components in the presence of a rubbery polymer, [(A)+(B)=100 pts.wt.]. Therein, the vinylic monomer components constituting the component B preferably comprises an aromatic vinyl compound, or the aromatic vinyl compound and one or more other vinylic monomers capable of being copolymerized with the aromatic vinyl compound. The other copolymerizable vinylic monomers preferably include vinylic monomers each having at least one kind of functional group selected from hydroxyl group, carboxyl group, acid anhydride group, epoxy group, oxazoline group, maleimide group, ester group, amide group, amino group and ether group.
