Abstract
An ionogenic compound, soluble or dispersible in aziridine compounds is utilized for delaying the polymerization of aziridine compounds initiated by a sulfonium salt. Said ionogenic compounds contain an anion which is more nucleophilic than the anion present in the sulfonium salt employed. Moreover, a preparation for dental purposes is described which contains these components.
