Benzophenone uv-absorbers with heterocyclic substituents

Compounds having the formula: wherein R1 represents hydrogen, C1-C20 alkyl which is unsubstituted or substituted by one or more ammonium, mono-, di-, tri or tetra-C1-C12 alkylammonium groups or by one or more sulphonium groups or represents an aralkyl residue having a total of from 7 to 10 carbon atoms and, in which, the aryl group is unsubstituted or substituted by C1-C4alkyl, C1-C4 alkoxy or halogen and Z is a group selected from R2, R3 and R4, independently, representing hydrogen, C1-C4alkyl, C1-C4 alkoxy, halogen, NHCOC1-C4 alkyl or phenyl which is unsubstituted or substituted by. C1-C4 alkyl, C1-C4 alkoxy or halogen, a process for their preparation and use of the compounds of formula (1) as UV-absorbers which have improved absorption spectrum characteristics, superior resistance to exposure to UV light and excellent thermal stability, relative to known benzophenone compounds.

Novel red-shifted triazine ultravioletlight absorbers

The present invention relates to novel red-shifted UV absorbers comprising 1,3,5-triazine structures containing a 2-naphthol-derived substituent. The present invention also relates to a method for stabilizing a material by incorporating into such material, e.g., organic material, the novel red-shifted triazine compounds in an amount effective to stabilize the material against the effects of actinic radiation.

Method for preparing nitroxides

The invention concerns a method for preparing nitroxides, which consists in oxidising, in a two-phase medium, using an aliphatic peroxide, secondary amines with steric hindrance or having a —CH in the nitrogen atom α.
