ABSTRACT:
The present invention relates to novel piperazine-piperidine compounds of the general formula (I) ##STR1## in which R.sub.1 is e.g. hydrogen or methyl, R.sub.2 is e.g. ethylene, m is zero or 1 and n is e.g. 1, and when n is 1, A is e.g. 2,2-dimethyl-1-propanoyl, n-butoxycarbonyl, n-tetradecyloxycarbonyl or 2,4-bis[N-butyl-(2',2',6',6'-pentamethyl-4'-piperidyl)amino]triazin-6-yl.
The said compounds are effective as light stabilizers, heat stabilizers and oxidation stabilizers for organic materials.
