ABSTRACT:
Compounds of the formula (I) ##STR1## wherein R.sub.1 and R.sub.5 are independently hydrogen, C.sub.1 -C.sub.12 -alkyl, C.sub.5 -C.sub.7 -cycloalkyl or a group of the formula (II), ##STR2## R.sub.2, R.sub.3 and R.sub.4 are independently C.sub.2 -C.sub.12 -alkylene, R is a group of the formula (III) ##STR3## wherein R.sub.6 is C.sub.2 -C.sub.8 -dialkylamino, C.sub.1 -C.sub.4 -alkoxy, a 5-membered to 7-membered heterocyclic group containing a nitrogen atom which is attached to the triazine residue or a group of the formula (IV), ##STR4## R.sub.7 and R.sub.8 are independently C.sub.1 -C.sub.12 -alkyl, C.sub.5 -C.sub.7 -cycloalkyl, benzyl or a group of the formula (II), subject to the proviso that both, R.sub.1 and R.sub.5 are different from hydrogen, if R is a group ##STR5## are useful as light stabilizers, heat stabilizers and/or oxidation stabilizers for organic materials, in particular synthetic polymers.
