ABSTRACT:
The compounds of the formula (I) ##STR1## in which R.sub.1 is C.sub.1 -C.sub.8 -alkyloxy, allyloxy, allylamino, di(C.sub.1 -C.sub.4 -alkyl)-amino, diallylamino, a 5-membered to 7-membered nitrogen containing heterocyclic group with the nitrogen atom linked to the triazine ring, or a group of the formula (II), ##STR2## R.sub.2 is hydrogen, O, OH, NO, CH.sub.2 CN, C.sub.1 -C.sub.8 -alkyl, allyl, benzyl, C.sub.1 -C.sub.8 -acyl, C.sub.1 -C.sub.18 -alkyloxy, C.sub.5 -C.sub.12 -cycloalkyloxy or OH-monosubstituted C.sub.2 -C.sub.4 -alkyl, R.sub.3 and R.sub.5 independently are hydrogen, C.sub.1 -C.sub.12 -alkyl, C.sub.5 -C.sub.12 -cycloalkyl, C.sub.7 -C.sub.9 -phenylalkyl, tetrahydrofurfuryl, C.sub.2 -C.sub.4 -alkyl monosubstituted by OH, by C.sub.1 -C.sub.4 -alkyloxy or by di(C.sub.1 -C.sub.4 -alkyl)amino, or a group of the formula (III) ##STR3## with R.sub.2 as defined above, R.sub.4 is hydrogen, C.sub.1 -C.sub.12 -alkyl or cyclohexyl and n is an integer from 2 to 6, are useful as light stabilizers, heat stabilizers and oxidation stabilizers for organic materials, in particular synthetic polymers.
