ABSTRACT:
The present invention is a cyanate-epoxy composite resin composition comprised of a cyanate ester resin (A), an epoxy resin (B), and a latent curing agent (C), characterized in that the latent curing agent (C) is composed of a modified polyamine (c1), a phenol resin (c2) and one or more kind of polycarboxylic acid (c3). The above modified polyamine (c1) is a modified polyamine, which is obtained by the reaction of polyamine compound (c1-1) with epoxy compound (c1-2), containing one or more amino group having an active hydrogen within a molecule.
