Abstract

The instant invention relates to novel tris(hydroxyphenyl)triazines coating compositions, for instance automotive coating compositions, and to novel tris(hydroxyphenyl) triazines UV-absorbers having a long wavelength sifted absorption spectrum with significant absorbance up to 420 nm. Further aspects of the invention are a UV stabilized composition containing the novel UV-absorbers, a process for the stabilization of organic materials and coatings and the use of the compounds as UV-light stabilizers for organic materials and coatings.
