ABSTRACT:
Oligomeric or polymeric siloxanes of the formula I ##STR1## if X is a monovalent radical, or which are correspondingly crosslinked, if X is a polyvalent radical, whose repeating units are arranged randomly or in blocks, which contain hydroxy-phenyl-diaryl-s-triazine moieties, are useful as stabilizers for organic material against damage thereto by light, oxygen and heat; and especially as stabilizers for coating materials.
