Abstract
The present invention relates to novel piperidine-triazine compounds of the general formula (I) ##STR1## in which R.sub.1 e.g. hydrogen or methyl, .lambda. is e.g. 1 and R.sub.2 and R.sub.3 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.
