Abstract: The invention relates to the use of 1, 3 substituted imidazolium salts of the formula (I), R1 and R3 independently representing an organic group having 1 to 20 C atoms, R2, R4, and R5 independently representing a H atom or an organic group having 1 to 20 C atoms, R4 and R5 also together being able to form an aliphatic or aromatic ring, X representing an anion having a pK B value of less than 13 (measured at 25°C, 1 bar in water or dimethylsulfoxide), and n representing 1, 2 or 3, where 1-ethyl-2,3-dimethylimidazolium acetate and 1-ethyl-2,3-dimethylimidazoliumacetate-acetic acid complex are excluded as the imidazolium salt, as a latent catalyst for curing compositions comprising epoxy compounds.
