The invention refers to salts of at least one imidazole of the general formula (I), in which R1, R2, R3 and R4 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.
