A-18405/A/CHM 56 Piperidine-triazine compounds for use as stabilisers for organic materials Abstract of the Disclosure The present invention relates to novel piperidine-triazine compounds of the formula (I) (I) Image in which R1 is e.g. hydrogen or methyl, A1 is e.g.>N-CH3, R2 is e.g.-(CH2)2-6-,R3 is e.g. 2,2,6,6-tetramethyl-4-piperidyl or 1,2,2,6,6-pentamethyl-4-piperidyl, or -A1-R2- is a direct bond and, in this case, R3 is e.g. a group Image or Image is a group of the formula (IVa) or (IVc) Image q and m are e.g. zero, X1 is e.g. a group of the formula (Va) Image (Va) in which A4 and A5 which are identical or different are e.g. an >N-R8 group where R8 is e.g. hydrogen, 2,2,6,6-tetramethyl-4-pipelidyl or 1,2,2,6,6,pentamethyl-4-piperidyl, Rg is e.g. -(CH2)2-6-,n is e.g. a number from 1 to 10, Y1 is e.g. OH, ONa, OK or a group -X1Z with Z being hydrogen or methyl and Y2 is e.g. hydrogen or methyl. The compounds of the formula (I) are effective as light stabilisers, heat stabilisers and oxidation stabilisers for organic materials.
