ABSTRACT:
2-(Benzotriazol-2-yl)-4-alkyl-6-(2-hydroxy-3-benzoyl-6-alkoxybenzyl)phenols are prepared by reacting a Mannich base of a 2-(2-hydroxy-5-alkylphenyl)-2H-benzotriazole with a 2-hydroxy-4-alkoxybenzophenone. The hybrid products exhibit outstanding efficacy in protecting organic substrates from light-induced deterioration as well as good resistance to loss by volatilization or exudation during the processing of stabilized compositions at elevated temperatures.
