The present invention relates to novel piperidine-triazine compounds of the general formula (I)
in which R₁ is e.g. hydrogen or methyl, λ is e.g. 1 and R₂ and R₃ are e.g. N-(2,2,6,6-tetramethyl-4-piperidyl)-tetrahydrofurfurylamino or 1,2,2,6,6-pentamethyl-4-piperidyloxy.
These compounds are effective as light stabilizers, heat stabilizers and oxidation stabilizers for organic materials.
