Abstract:
The use of 1,3-substituted imidazolium salts of the formula I in which R1 and R3 independently of one another are an organic radical having 1 to 20 C atoms, R2, R4, and R5 independently of one another are an H atom or an organic radical having 1 to 20 C atoms, it also being possible for R4 and R5 together to form an aliphatic or aromatic ring, and X is a thiocyanate anion as latent catalysts for curing compositions comprising epoxy compounds.
