To provide a resin composition for a prepreg, which is a resin composition for a prepreg comprising a urethane (meth)acrylate (A) and a polymerization initiator (B) as essential components, The above-mentioned urethane (meth)acrylate (A) is a reaction product of polyisocyanate (a1), polyol (a2) and hydroxyalkyl (meth)acrylate (a3), and the above-mentioned polyisocyanate (a1) is Selected from 2,4'-diphenylmethane diisocyanate, 4,4'-diphenylmethane diisocyanate, carbodiimide-modified products of 4,4'-diphenylmethane diisocyanate, and polymethylene One or more kinds of polyisocyanates among the polyphenyl polyisocyanates, wherein the polyol (a2) has an aromatic ring and an oxyalkylene structure. The resin composition for prepregs of the present invention is excellent in handleability and moldability, and can obtain molded articles excellent in various physical properties such as appearance and heat resistance, and thus can be suitably used for prepregs and molded articles thereof. |
