Abstract: A curable epoxy composition comprises 100 parts by weight of an epoxy resin composition comprising one or more epoxy resins, each independently having an epoxy equivalent weight of at least 2; 30 to 200 parts by weight of an aromatic dianhydride curing agent of the formula wherein T and y are as provided herein; and 0.1 to 5 parts by weight of a heterocyclic accelerator, based on the total parts by weight of the epoxy resin composition and the aromatic dianhydride curing agent, wherein the heterocyclic accelerator comprises a substituted or unsubstituted C3-6 heterocycle comprising 1 to 4 ring heteroatoms, wherein each heteroatom is independently the same or different, and is nitrogen, oxygen, phosphorus, silicon, or sulfur, wherein the composition does not contain a monoanhydride curing agent.
