are the same or different and denote hydrogen, an alkyl residue having 1 to 20, preferably 1 to 10, more preferably 1 to 4 carbon atoms, or a substituted or unsubstituted aryl or arylalykl residue having 6 to 10 carbon atoms, and at least one aliphatic or aromatic mono- or dicarboxylic acid. The molar ratio of carboxylic acid to imidazole, based on the functionality of the acid, is 1:1.1 to 1:6. The invention also relates to a method for manufacturing the imidazole salts, to their use, and to epoxy resin compositions containing said salts.
