Emulsifying epoxy resin composition and curable composition

A curable composition comprising:

• (I) an epoxy resin having, on the average, more than one epoxy group having an oxygen atom bonded to adjacent carbon atoms in its molecule,
• (II) an emulsifiable epoxy compound which is prepared by reacting an urethane compound (II-1), prepared by the reaction of a polyalkylene polyether polyol compound (II-1-1) having a number average molecular weight of 200 to 12,000 and an ethylene oxide content of 80% by weight or above with an excess amount of a polyisocyanate compound (II-1-2), with an epoxy compound (II-2) having, on the average, at least 0.1 hydroxyl group and at least one epoxy group having an oxygen atom bonded to adjacent carbon atoms and an alkylphenol ethoxylate (II-3) having a number average molecular weight of 300 to 5,000 at a molar ratio of (II-1):(II-2):(II-3) of 1.0:1.0-10.0:0.1-2.0, with the proviso that the equivalent ratio of the total hydroxyl content in (II-2) and (II-3) to the isocyanate content in (II-1) must be 1.0 or above,
• (V) a solvent,
• (III) water, and
• (IV) an active organic amino compound.
