(57) Abstract: An epoxy resin emulsion capable of forming a film having improved weather resistance and flexibility without impairing water resistance and toughness, which are characteristics of epoxy resin, and an aqueous coating composition containing the same. I will provide a. SOLUTION: Polyethylene glycol (a) having a number average molecular weight of 400 to 20,000, bisphenol type epoxy resin (b), compound (c) having one active hydrogen in one molecule and one molecule Two or more active isocyanates The modified epoxy resin (A) obtained by the reaction of the compound (d) having a thio group is used as a dispersion-stable resin, and the acryl-modified epoxy resin (B) is dispersed in water to obtain an epoxy resin emulsion. |
