摘要： An epoxy resin composition having high epoxy curing property and sufficient storage stability, and an epoxy curing agent therefor. The curing agent or the cure accelerating agent obtained by treating the surfaces of (1) an epoxy adduct obtained by adding a nitrogen-containing heterocyclic compound, an aliphatic amine or an aromatic amine to an epoxy compound having one, two or more epoxy groups in one molecule, with (2) a boric acid compound or (3) a boric acid compound and a phenolic compound, exhibits high curing property and storage stability, and can be favorably used as a curing agent for the epoxy resin composition. The epoxy resin composition prepared by mixing the epoxy resin with (1) and (2) or (1) and (3), exhibits excellent curing property and storage stability.
