Abstract:
1. A curable resin material comprising: a curable resin composition (X), and a thermoplastic resin (Y); wherein the difference between solubility parameters of resins (X) and (Y) is 0.5 to 3.0, and the thermoplastic resin (Y) has a weight-average molecular weight of 60,000 to 100,000; said curable resin composition (X) consisting of one of two curable resin compositions (X1) or (X3), wherein: (X1) is the combination of a curable resin (A) and a compound (B) having a molecular weight of 170 to 3,000 and a crosslinking functional group, wherein curable resin (A) has, in its molecule, at least two crosslinking functional groups of at least one group selected from the group consisting of an epoxy group, a (meth)acryloyl group, an alkenylamino group and an alkenyloxy group and has a glass transition temperature before curing of 50 to 150° C., and a weight-average molecular weight of 10,000 to 1,000,000; and wherein curable resin (B) has, in its molecule, at least two crosslinking functional groups of at least one group selected from the group consisting of an epoxy group, a (meth)acryloyl group, an alkenylamino group and an alkenyloxy group; and (X3) is the combination of: a copolymer (J), which has a Mw of 2,000 to 1,000,000, formed from the monomers selected from the group consisting of monomers (f) having an epoxy group and a (meth)acryloyl group, monomers (g) having an epoxy group and a vinyl group, monomers (h) having a (meth)acryloyl group and a vinyloxy group, monomers (i) having a (meth)acryloyl group and an allyloxy group, monomers (j) having a (meth)acryloyl group and an propenyloxy group, monomers (v) having an allylamino group and monomers (w) having a propenylamino group, wherein at least one of monomers (f, g and w) is selected for the copolymer; and a monomer (3), (4) or (5) having formula 3, 4 or 5, respectively, as follows: wherein n is an integer of 1 to 10; wherein R 1 is hydrogen or methyl, m is an integer of 0 to 6, and n is an integer of 1 to 10; wherein R 3 is hydrogen or fluorine, R 4 is hydrogen, chlorine, or fluorine, and R 5 is hydrogen, fluorine, or trifluoromethyl.
