The present invention relates to novel piperidine-triazine compounds of the general formula (I)
in which R₁ and R₆ are e.g. isooctylamino or N-(2,2,6,6-tetramethyl-4-piperidyl)-butylamino, R₂ and R₅ are e.g. 2,2,6,6-tetramethyl-4-piperidyl, R₃ and R₄ are e.g. alkylene, R₇ is e.g. a group
m is zero or 1, n is zero, 1, 2, 3 or 4, p is 1 to 50, X is e.g. as defined for R₁ and Y is e.g. a group
The said compounds are effective as light stabilizers, heat stabilizers and oxidation stabilizers for organic materials.
