摘要：
A water-dilutable epoxide which is free from glycidyl ester and glycidyl ether groups, characterized in that it contains, in addition to at least one epoxide group, at least one ester group of a monocarboxylic acid and a further ester group which is vicinally arranged thereto, this further ester group having been obtained by reaction of an OH group with a polycarboxylic monoanhydride, wherein the second COOH group formed from the anhydride by the esterification occurs wholly or partially in the form of a salt with a base; processes for preparing it and the use thereof in aqueous media or media compatible with water.
