Abstract
o-Hydroxyphenyl-s-triazines of the formula I ##STR1## in which n is 1 to 4 and R.sub.1 to R.sub.7 are as defined in claim 1, can be used, in combination with sterically hindered amines of the polyalkylpiperidine type, for stabilizing organic polymers. Some of these compounds are novel and can also be used without polyalkylpiperidine.
