An aqueous self-emulsifiable epoxy resin curing agent which is produced by reacting, with each other, an (A) polyamine (meta-xylylenediamine, etc), a (B) epoxy group-containing alkoxypolyethylene polyether compound (methoxypolyethyleneglycol glycidyl ether, etc.) having 500 to 5000 average molecular weight, at least one (C) hydrophobic epoxy compound having at least one epoxy group in the molecule (butyl glycidyl ether, epoxy resin of type bisphenol A or F, etc.) and optionally, a (D) unsaturated compound capable of addition reaction (acrylonitrile, methyl methacrylate, etc.), in a molar quantity of the epoxy group in (B) of 0.001 to 0.1 mol and in a molar quantity of the sum of the epoxy group in (C) and the unsaturated group in (D) of 0.2 to 0.5 mol, each based on 1 mol of a hydrogen atom bonded to a nitrogen atom in (A) which is capable of reacting with an epoxy group or a unsaturated group.
An aqueous self-emulsifiable epoxy resin curing agent which is produced by reacting, with each other, an (A) polyamine, a (B) epoxy group-containing alkoxypolyethylene polyether compound having an average molecular weight of 500 to 5000 and at least one (C) hydrophobic epoxy compound having at least one epoxy group in the molecule in molar quantities of the epoxy group in (B) and that in (C) of 0.001 to 0.1 mol and 0.2 to 0.5 mol, respectively each based on 1 mol of a hydrogen atom bonded to a nitrogen atom in (A) which is capable of reacting with an epoxy group, said compound (B) being represented by the general formula (1) ##STR4## wherein R is an alkyl group having 1 to 28 carbon atoms, and n is a real number from 10 to 110.
