ABSTRACT:
Compounds having the formula ##SPC1##
Wherein R is alkyl, alkylene, phenyl, phenylene or alkyl substituted phenyl or phenylene, n is one or two and X is hydrogen, hydroxyl or oxygen, are good light stabilizers. These compounds are prepared, for example, from 1,3,3-trimethyl-3-azabicyclo[2.2.2]octane-5-ol and stearic acid to give 5-stearoyloxy-1,3,3-trimethyl-2-azabicyclo[2.2.2]octane which is converted by standard techniques to the corresponding 2-oxyl and 2-ol compounds.
