The present invention relates to initiators of the general formula {[M(L)]X}, wherein said initiators preferably have (SbF) as a counterion and are obtainable by a complexing reaction of a corresponding metal-SbFsalt with a corresponding ligand (L). The present invention further relates to preparations and epoxy resin systems that contain such initiators and, in particular, are non-thermally and/or thermally curable.

Metal compounds for use as initiators

The use of 1,3-substituted imidazolium salts of the formula I in which

Catalyst for curing epoxides

1,3-substituted imidazolium salts of the formula I are used as latent catalysts for curing compostions comprising epoxy compounds: 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; X is the anion of a phosphorus oxyacid, and n is 1, 2 or 3.
