ABSTRACT:
A hardenable epoxy resin composition hardenable at a temperature from about 0.degree. to 5.degree.C. is made by mixing (A) one or more epoxy compound (I) containing on the average more than one adjacent epoxy group per molecule with (B) one or more reaction product (II) produced by reacting (1) a reaction product (II-1) produced by reacting essentially (1--1) a phenol (a) having at least one reactive hydrogen atom attached to aromatic nucleus and (1-2) a polyamine (b) having one or more active hydrogen atoms attached to amino nitrogen atom per molecule and (1-3) a member selected from the group comprising carbonyl compounds having one or more carbonyl groups per molecule and its reactive derivatives (c) in the mole ratio of a phenol (a); a polyamine (b): a member selected from the group comprising a carbonyl compounds and its reactive derivatives (c) being 1: at least 1: at least 1 (mole:mole:mole), and (2) a phenol (d) in the ratio of equivalence of phenolic hydroxy group of a phenol (d): equivalence of active hydrogen atom attached to amino nitrogen atom of the reaction product (II-1) being 0.1 - 1.0 : 1.
