Abstract

Abstract Compounds which contain, in their molecule, at least one 2-(2'-hydroxyphenyl)-benztriazole group or one 2-hydroxybenzophenone group and at least one polyalkylpiperidine group are effective light stabilizers for organic materials, in particular for polymers. The use of the compounds as light stabilizers for lacquers is of particular importance.
