Abstract

The invention relates to triazine-based special organic UV absorbers modified in such a way as to be soluble in polar coating compositions. The invention further relates to coatings, e.g. sol-gel based ones, containing said novel UV absorbers as well as to the use of said coatings for permanently protecting materials, especially plastics, from photochemical degradation.
