Abstract:
1. A thermosetting resin composition, comprising: (1) a resin including: (a) a monomer unit represented by the following general formula (I): wherein R 1 represents a hydrogen atom, a halogen atom, or a hydrocarbon group having 1 to 5 carbon atoms; R 2 or each of R 2 's independently represents a halogen atom, an aliphatic hydrocarbon group having 1 to 5 carbon atoms, or an aromatic hydrocarbon group; x is an integer of 0 to 3; and m is a natural number, and (b) a monomer unit represented by the following general formula (II) wherein n is a natural number; and (2) a cyanate resin having two or more cyanate groups per molecule, wherein the copolymerization ratio mm between the monomer units in said resin (1) is from 0.8 to 19, and wherein the resin (1) further comprises, as a monomer unit, (c) N-phenylmaleimide represented by the following general formula (III): wherein R 3 represents a halogen atom, an aliphatic hydrocarbon group having 1 to 5 carbon atoms, an aromatic hydrocarbon group, a hydroxyl group, a thiol group, or a carboxyl group: y is an integer of 0 to 3: and r is a natural number, and/or a derivative thereof.
