Beschreibung
Zusammenfassung:	An object of the present invention is to provide a water-soluble epoxy resin that has high water-solubility, maintains emulsion stability for epoxy resin, and is capable of forming a cured product that has excellent coating film strength and corrosion resistance. Another object is to provide a cured product that has water resistance, alkali resistance, and higher coating film strength and corrosion resistance. The present invention provides a water-soluble epoxy resin obtained by causing an epoxy resin (B) having two or more epoxy groups in a molecule to react with a carboxy-group-containing compound (A) obtained by reacting a polyethylene glycol monoalkyl ether (A-1) having a number-average molecular weight of 400 to 10000 and an acid anhydride (A-2) derived from a polyvalent carboxylic acid; a water-soluble epoxy resin composition containing the water-soluble epoxy resin and an epoxy resin having two or more epoxy groups in a molecule; and a water-based epoxy resin composition in which the water-soluble epoxy resin composition is dispersed in an water-based solvent.
