Abstract
Abstract Sulfonium salts of the formulae I to IV ##STR1## in which A is C 1 -C 12 alkyl, C 3 -C 8 cycloalkyl, C 4 -C 10 cycloalkylalkyl, phenyl which is unsubstituted or mono- or polysubstituted by C 1 -C 8 alkyl, C 1 -C 4 alkoxy, halogen, nitro, phenyl, phenoxy, alkoxycarbonyl having 1-4 C atoms in the alkoxy radical or acyl having 1-12 C atoms, Ar, Ar 1 and Ar 2 , independently of one another, are each unsubstituted or mono- or polysubstituted phenyl, or naphthyl which is unsubstituted or mono- or polysubstituted each arylene is an unsubstituted or mono- or polysubstituted phenylene or unsubstituted or mono- or polysubstituted naphthylene and Q.sup.⊖ is SbF 6 --, AsF 6 -- or SbF 5 OH-- are valuable curing agents and curing accelerators in the heat-curing of cationically polymerizable compounds, preferably epoxy resins.
