Piperidine-triazine compounds of the general formula (I)
in which R₁ is e.g. hydrogen or methyl, R₂ is e.g. 2,2,6,6-tetramethyl-4-piperidyloxy or 1,2,2,6,6-pentamethyl-4-piperidyloxy, m is e.g. 2, 3 or 4, and, if m is 2, R₃ is e.g. a group of the formula (IIIc) or (IIIe)
in which R₁₀ and R₁₂ which can be identical or different are e.g. hydrogen, cyclohexyl, 2,2,6,6-tetramethyl-4-piperidyl or 1,2,2,6,6-pentamethyl-4-piperidyl, R₁₁ is e.g. C₂-C₆alkylene, R₁₄ is e.g. hydrogen or methyl and p is e.g. 2, and, if m is 3 or 4, R₃ is e.g. a group of the formula (IV)
in which R₁₅ and R₁₉ which can be identical or different are e.g. hydrogen, 2,2,6,6-tetramethyl-4-piperidyl or 1,2,2,6,6-pentamethyl-4-piperidyl, R₁₆, R₁₇ and R₁₈ which can be identical or different are e.g. C₂-C₃alkylene and q is e.g. zero or 1, are effective as light stabilizers, heat stabilizers and oxidation stabilizers for organic materials.
