ABSTRACT:
The novel compounds of the formula (I) ##STR1## in which R.sub.1 is di(C.sub.1 -C.sub.4 -alkyl)amino, C.sub.1 -C.sub.4 -alkoxy, a 5-membered to 7-membered nitrogen containing heterocyclic group with the nitrogen atom bonded to the triazine ring, or a group of the formula (II), ##STR2## R.sub.2 and R.sub.4 which are identical or different are C.sub.1 -C.sub.12 -alkyl, C.sub.5 -C.sub.7 -cycloalkyl, benzyl or 1,2,2,6,6-pentamethyl-4-piperidyl, n is 2 or 3 and, if n is 2, R.sub.3 is a group ##STR3## with R.sub.5 and R.sub.7, which are identical or different, being hydrogen, C.sub.1 -C.sub.12 -alkyl, C.sub.5 -C.sub.7 -cycloalkyl, benzyl or 1,2,2,6,6-pentamethyl-4-piperidyl and R.sub.6 being C.sub.2 -C.sub.12 -alkylene, cyclohexylene, cyclohexylenedimethylene or methylenedicyclohexylene, or R.sub.3 is the divalent radical of a 6-membered to 7-membered heterocyclic compound with two nitrogen atoms which are each bonded to a triazine ring, or, if n is 3, R.sub.3 is a group ##STR4## with R.sub.8 and R.sub.11, which are identical or different, being as defined above for R.sub.5 and R.sub.7, and R.sub.9 and R.sub.10, which are identical or different, being C.sub.2 -C.sub.12 -alkylene, are useful as light stabilizers, heat stabilizers and oxidation stabilizers for organic materials.
