The present invention relates to novel piperidine-triazine compounds of the general formula (I) ##STR1## in which R 1 is e.g. methyl, acetyl or (C 1 -C 2 alkoxy)carbonyl, A is e.g. a group of the formula (IIa), ##STR2## in which R 3 is e.g. hydrogen, methyl, 2,2,6,6-tetramethyl-4-piperidyl, 1,2,2,6,6-pentamethyl-4-piperidyl or 1-acetyl-2,2,6,6-tetramethyl-4-piperidyl, R 4 is e.g. C 3 -C 6 alkylene, R 2 is e.g. a group R 1 -A- and n is e.g. a number from 1 to 5. n The said compounds are effective as light stabilizers, heat stabilizers and oxidation stabilizers for organic materials. |
