A curable composition comprising an epoxy resin and an aromatic azopolyamine curing agent is described. The azopolyamine curing agent is preferably a compound according to the formula Image in which each R is selected independently from H and C1-C4 alkyl; R' is a substituted or unsubstituted aromatic or bisaromatic group; and m is 1 or 2. Such compounds are generally the reaction products of a diazonium salt with an aromatic diamine, and include a large number of compounds known in the art of azo dyes. The use of azopolyamine curing agents in reactive monomer-diluted systems results in a high-modulus cured epoxy system.
