ABSTRACT:
Piperidine-triazine compounds of the general formula (I) ##STR1## in which R.sub.1 is e.g. hydrogen or methyl, R.sub.2 is e.g. 2,2,6,6-tetramethyl-4-piperidyloxy or 1,2,2,6,6-pentamethyl-4-piperidyloxy, m is e.g. 2,3 or 4 and, if m is 2, R.sub.3 is e.g. a group of the formula (IIIc) or (IIIe) ##STR2## in which R.sub.10 and R.sub.12 which can be identical or different are e.g. hydrogen, cyclohexyl, 2,2,6,6-tetramethyl-4-piperidyl or 1,2,2,6,6-pentamethyl-4-piperidyl, R.sub.11 is e.g. C.sub.2 -C.sub.6 alkylene, R.sub.14 is e.g. hydrogen or methyl and p is e.g. 2, and, if m is 3 or 4, R.sub.3 is e.g. a group of the formula (IV) ##STR3## in which R.sub.15 and R.sub.19 which can be identical or different are e.g. hydrogen 2,2,6,6-tetramethyl-4-piperidyl or 1,2,2,6,6-pentamethyl-4-piperidyl, R.sub.16, R.sub.17 and R.sub.18 which can be identical or different are e.g. C.sub.2 -C.sub.3 alkylene and q is e.g. zero or 1, are effective as light stabilizers, heat stabilizers and oxidation stabilizers for organic materials.
