摘要：
Compounds of the formula I ##STR1## in which R.sub.1, is aryl, R.sub.2 is hydrogen, --OH or alkyl, R.sub.3 is hydrogen or alkyl, R.sub.4 is hydrogen, aryl, alkenyl, furyl or --CCl.sub.3, when n is 1, R.sub.5 is alkyl, aryl, camphoryl, --CF.sub.3 or fluoro, or when n is 2, R.sub.5 is alkylene or arylene, are latent curing catalysts for acid-curable stoving varnishes. On irradiation, the active curing catalysts which lead to acid-catalyzed curing of the resins are formed from the compounds of the formula I.
