ABSTRACT:
The present invention relates to novel piperidine-triazine compounds of the general formula (I) ##STR1## in which R.sub.1 is e.g. hydrogen or methyl, A is e.g. --O--, m is e.g. 3, R.sub.2 is e.g. a group --OR.sub.4 or ##STR2## R.sub.4 is e.g. C.sub.1 -C.sub.4 alkyl, 2,2,6,6-tetramethyl-4-piperidyl or 1,2,2,6,6-pentamethyl-4-piperidyl, R.sub.5 and R.sub.6 which can be identical or different are e.g. C.sub.1 -C.sub.8 alkyl, cyclohexyl, tetrahydrofurfuryl, a group ##STR3## 2,2,6,6-tetramethyl-4-piperidyl or 1,2,2,6,6-pentamethyl-4-piperidyl, or R.sub.5 can also be hydrogen, or ##STR4## is e.g. 4-morpholinyl, n is 1, 2, 3 or 4 and, if n is 1, R.sub.3 is e.g. as defined above for R.sub.2 and, if n is 2, R.sub.3 is e.g. a group --E.sub.1 --R.sub.8 --E.sub.2 -- in which E.sub.1 and E.sub.2 which can be identical or different are e.g. >N-R.sub.12, R.sub.8 is e.g. C.sub.2 -C.sub.6 alkylene, C.sub.8 -C.sub.10 alkylene interrupted by 2 or 3 oxygen atoms or methylenedicyclohexylene and R.sub.12 is e.g. hydrogen, methyl, 2,2,6,6-tetramethyl-4-piperidyl or 1,2,2,6,6-pentamethyl-4-piperidyl, and, if n is 3, R.sub.3 is e.g. a group ##STR5## in which R.sub.12 is e.g. as defined above and R.sub.13 and R.sub.14 which can be identical or different are e.g. C.sub.2 -C.sub.3 alkylene, and, if n is 4, R.sub.3 is e.g. a group ##STR6## in which R.sub.12 is e.g. as defined above and R.sub.20 and R.sub.21 which can be identical or different are e.g. C.sub.2 -C.sub.3 alkylene.
These compounds are effective as light stabilizers, heat stabilizers and oxidation stabilizers for organic materials.
