摘要：
The invention relates to novel benzotriazole UV-absorbers having a long wavelength shifted absorption spectrum with significant absorbance up to 410-420 nm. Further aspects of the invention are a process for their preparation, a UV stabilized composition containing the new UV-absorbers and the use of the new compounds as UV-light stabilizers for organic materials.
