PROCESS FOR CURING STOVING LACQUERS

摘要

Acid addition salts of basic polyalkylpiperidine derivatives, which contain a group of the formula I (I) < IMG > in which R is H or CH3, and an inorganic or organic acid, and also inner salts of sulfonic acids which contain a group of the formula I, are suitable as curing catalysts for acid-curable stoving lacquers. Their advantage is a long pot life and also an additional light stabilising action.
