Abstract
A resin composition useful as a matrix resin for a composite material comprises (A) from 30-80% by weight of an amino group-containing unsaturated ester compound obtained by ring-opening addition reacting an epoxy group-containing unsaturated compound (c) with an aromatic polyamine (a) or diamine (b) in an equivalent weight ratio of compound (c) to amino hydrogen atom of polyamine (a) or diamine (b) of from 0.25-0.9:1, (B) from 10-60% by weight of a polyepoxy compound, and (C) from 5-60% by weight of a radically polymerizable cross-linking agent such as p-methyl styrene.
