Abstract:
1. A curable resin composition comprising, an unsaturated resin (A) having a methacryloyl group, the unsaturated resin (A) being a solid resin at ordinary temperatures produced by reacting at least one of a dicyclopentadiene-based novolac epoxy resin and a biphenyl-based novolac epoxy resin with only methacrylic anhydride or with only methacrylic acid and methacrylic anhydride, the unsaturated resin (A) having a double bond equivalent weight of 210 to 400, an ester number of 100 to 300, and a hydroxyl number of no more than 130; an ethylenically unsaturated monomer (B) selected from a group consisting of styrene, t-butylstyrene, vinylnaphthalene, vinylbiphenyl, pentafluorostyrene, vinylpyrene, vinylthiophene, vinylcarbazole, divinylbenzene, divinylnaphthalene, divinylbiphenyl, dicyclopentenyl methacrylate, dicyclopentenyloxyethyl methacrylate, dicyclopentanyl methacrylate, adamantane methacrylate, 1,10-dodecanediol dimethacrylate, cyclohexanedimethanol dimethacrylate, and tricyclodecanedimethanol dimethacrylate; and a radical polymerization initiator (C); wherein the viscosity of resin (A), which is solid at ordinary temperatures, can be measured when dissolved in the ethylenically unsaturated monomer (B), with the viscosity preferably being in a range of 500 to 15,000 mPa·s at 25° C.
