ABSTRACT:
An addition product obtained by reacting (a) a polyfunctional epoxy compound and (b) a compound having at least one functional group of OH group, SH group, COOH group and CONHNH.sub.2 group together with a tertiary amino group in the molecule, and an addition product obtained (a), (b) and (c) an organic compound having two or more active hydrogen atoms in the molecule (excluding a compound having an epoxy group or tertiary amino group) are good curing agents for epxoy resin. The curing agents are useful in formulating novel storable one-package, heat-curable epoxy resin-based compositions.
