    摘要: Compounds of the formula I and II ##STR1## in which R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6, X, Y and n are as defined in claim 1, are latent curing catalysts for acid-curable stoving lacquers. They are distinguished by satisfactory solubility in the acid-curable resin systems, can be stored virtually indefinitely in the dark and, when exposed to shortwave light, make it possible to cure the resins by acid catalysis at a relatively low temperature.
