PIPERIDINE-TRIAZINE COMPOUND FOR USE AS STABILIZER FOR ORGANIC MATERIAL

摘要

The present invention relates to novel piperidine-triazine compounds of the general formula (I) in which R1 is e.g. methyl, acetyl or (C1-C2alkoxy)carbonyl, A is e.g. a group of the formula (IIa), in which R3 is e.g. hydrogen, methyl, 2,2,6,6-tetramethyl-4-piperidyl, 1,2,2,6,6-pentamethyl-4-piperidyl or 1-acetyl-2,2,6,6-tetramethyl-4-piperidyl, R4 is e.g. C3-C6alkylene, R2 is e.g. a group R1-A- and n is e.g. a number from 1 to 5. The said compounds are effective as light stabilizers, heat stabilizers and oxidation stabilizers for organic materials.
