Abstract
o-Hydroxyphenyl-s-triazines of formula I ##STR1## wherein n is 1 or 2 and R.sub.1 to R.sub.7 are as defined in claim 7, are good light stabilizers for coating compositions which contain a basic curing catalyst. In contradistinction to other UV absorbers, they do not cause discolorations in the presence of such catalysts.
