    摘要: A curable epoxy resin composition comprises (I) an epoxy resin and (II) a curing agent. It may comprise (III) another curing agent. It is preferable for it to comprise 25 to 95 wt.% of (I) and 5 to 45 wt.% of (II).1 an epoxy resin (I) represented by the general formula: ##STR1## wherein Z represents a group selected from among a hydrogen atom, a methyl group and an ethyl group, R represents a group selected from among a hydrogen atom and alkyl groups, and n represents a number of 0 to 1.6, and2 a curing agent comprising a polyamine reaction composition (II) obtained by reacting 1 mol of a phenol (II-1) having at least one unsubstituted reactive site in the aromatic nucleus with at least 1 mol of an aliphatic polyamine (II-2) and at least 1 mol of a carbonyl compound (II-3) having at least one carbonyl group in the molecule.
