Abstract
Abstract The novel UV-absorbers are compounds of the formula I ##STR1## in which R 1 is, for example, hydrogen, n is one of the numbers 1 or 2 and R 2 is an appropriate monovalent or divalent radical, for example --OH or --O--CH 2 CH 2 --O--. The UV-absorbers are used in particular for stabilising and improving lacquers and photographic material.
