Abstract:
The instant invention relates to novel hydroxyphenyl triazine UV-absorbers with an aromatic carbocyclic fused ring system having a long wavelength shifted absorption spectrum with significant absorbance up to 420 nm. Further aspects of the invention are a process for their preparation, a UV stabilized composition containing the new UV-absorbers, a process for the stabilization of organic materials and the use of the new compounds as UV-light stabilizers for organic materials.
