The novel compounds of the formula (I)
in which R₁ is di(C₁-C₄-alkyl)amino, C₁-Ψ₄-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),
R₂ and R₄ which are identical or different are C₁-C₁₂-alkyl, C₅-C₇-cycloalkyl, benzyl or 1,2,2,6,6-pentamethyl-4-piperidyl, n is 2 or 3 and, if n is 2, R₃ is a group
with R₅ and R₇, which are identical or different, being hydrogen, C₁-C₁₂-alkyl, C₅-C₇-cycloalkyl, benzyl or 1,2,2,6,6-pentamethyl-4-piperidyl and R₆ being C₂-C₁₂-alkylene, cyclohexylene, cyclohexylenedimethylene or methylenedicyclohexylene, or R₃ 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, R₃ is a group
with R₈ and R₁₁, which are identical or different, being as defined above for R₅ and R₇, and R₉ and R₁₀, which are identical or different, being C₂-C₁₂-alkylene, are useful as light stabilizers, heat stabilizers and oxidation stabilizers for organic materials.
