ABSTRACT:
Hindered amines based on various 2,2,6,6-tetralkylated nitrogen-containing heterocyclic moieties wherein the hindered nitrogen atom on the ring is substituted with OH or OR substituents and the 4-position of the ring is substituted with a diversity of substituents are effective in protecting a variety of non-polyolefin substrates against the adverse effects of light, heat and oxygen.
