Abstract

A self-dispersible curable epoxy resin composition containing a reaction product of: (a) 1.0 equivalent of epoxy resin; (b) 0.01 to 1.0 equivalent of polyhydric phenol; and (c) 0.005 to 0.5 equivalent of an amine/epoxy adduct formed by reacting: (i) an aromatic polyepoxide; and (ii) a polyoxyalkylenamine, in an equivalent ratio of from about 1:0.10 to 1:0.28.
