Patent number: 5336706
Abstract: The present invention relates to novel piperidine-triazine compounds of the formula (I) ##STR1## in which R.sub.1 is e.g. hydrogen or methyl, A.sub.1 is e.g. >N--CH.sub.3, R.sub.2 is e.g. --(CH.sub. 2).sub.2-6 --, R.sub.3 is e.g. 2,2,6,6-tetramethyl-4-piperidyl or 1,2,2,6,6-pentamethyl-4-piperidyl, or --A.sub.1 --R.sub.2 -- is a direct bond and, in this case, R.sub.3 is e.g. a group ##STR2## is a group of the formula (IVa) or (IVc) ##STR3## q and m are e.g. zero, X.sub.1 is e.g. a group of the formula (Va)--A.sub.4 --R.sub.9 --A.sub.5 -- (Va)in which A.sub.4 and A.sub.5 which are identical or different are e.g. an >N--R.sub.8 group where R.sub.8 is e.g. hydrogen, 2,2,6,6-tetramethyl-4-piperidyl or 1,2,2,6,6-pentamethyl-4-piperidyl, R.sub.9 is e.g. --(CH.sub.2).sub.2-6 --, n is e.g. a number from 1 to 10, Y.sub.1 is e.g. OH, ONa, OK or a group --X.sub.1 Z with Z being hydrogen or methyl and Y.sub.2 is e.g. hydrogen or methyl.
