ABSTRACT:
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.
