Hindered amines based on various .2,2,6;6-tetcaalkylated nitrogen-containing heterocyclic moieties wherein the hindered nitrogen atom on the ring is substituted with OR1 substituents and the 4-position of the ring is substituted with a variety of groups, are effective as light stabilizers in diverse substrate systems. Some of them are new compounds.
基于各种.2,2,6;6-四烷基化含氮杂环分子的受阻胺,其中环上的受阻氮原子被 OR1 取代基取代,环的 4 位被各种基团取代,可在各种底物体系中有效地用作光稳定剂。其中一些是新化合物。
