Abstract
Compounds having the formula ##STR1## wherein R is alkylene, PA1 M is hydrogen or a metal, and PA1 m has a value of from 1 to 4, Are good light stabilizers. The amino acids may be formed, for example, from 1,3,3-trimethyl-3-azabicyclo[2.2.2]octane-5-ol and sebacic acid to give o-mono(1,3,3-trimethyl-2-azabicyclo[2.2.2]octane-5-ol)sebacate. The metal salts of the acids are readily prepared by reacting the acids or their salts with a reactive form of the metal or metal complex.
