, (2008/06/13)
A description is given of compounds of the formula wherein R and R' independently are H, methyl or ethyl. The novel compounds are effective as stabilizers for organic material against the damaging effect of light, oxygen and heat; they are also suitable for use in skin or hair protection preparations.

, (2008/06/13)
Compositions comprising an organic material liable to oxidative, thermal and/or actinic degradation and at least one compound of the formula I STR1 are described in which n is 1-6, R, R 1, R 2, R 3 and R 4 are preferably hydrogen and A is a monovalent radical or polyvalent linking moiety.Some of the compounds of the formula I are novel. They are particularly suitable for the stabilization of lubricating oils, metal processing fluids and hydraulic fluids, and of thermoplastics and elastomers.
Piperidine-triazine compounds for use as stabilizers for organic materials
-
, (2008/06/13)
The present invention relates to novel piperidine-triazine compounds of the general formula (I) STR1 in which R1 is e.g. methyl, acetyl or (C1 -C2 alkoxy)carbonyl, A is e.g. a group of the formula (IIa), STR2 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 -C6 alkylene, 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.
