Zusammenfassung:	This disclosure relates to reactive epoxy compounds that have high water solubility, core-shell type epoxy resin particles, a waterborne epoxy resin composition, and a coating composition. The reactive epoxy compounds are obtained by mixing an epoxy resin having at least two epoxy groups per molecule with a carboxyl group-containing compound obtained by reacting a polyetheramine comprising a primary amine and an acid anhydride derived from a polyvalent carboxylic acid. This disclosure also relates to waterborne epoxy resin composition comprising core-shell type epoxy resin particles dispersed in a solvent, wherein the particles are formed by an epoxy resin encapsulated in the reactive epoxy compounds of the present invention. The waterborne epoxy resin composition is low in volatile organic compounds. 本发明关于一种反应性环氧化合物、核-壳型环氧树脂颗粒、水性环氧树脂组合物及涂料组合物，该反应性环氧化合物具有高水溶性。藉由将每分子具有至少二个环氧基团的环氧树脂与含有羧基的化合物混合获得该反应性环氧化合物，其中该含有羧基的化合物是由包含一级胺的聚醚胺与衍生自多元羧酸的酸酐进行反应而获得。该水性环氧树脂组合物是一环氧树脂被包封于本发明的反应性环氧化合物中，形成核-壳型环氧树脂颗粒，并分散于溶剂中，该水性环氧树脂组合物是低
