ABSTRACT:
2-[2-Hydroxy-3,5-di-tert-octylphenyl]-2H-benzotriazole exhibits outstanding efficacy in protecting organic substrates from light induced deterioration as well as good resistance to loss by volatilization or exudation during the high temperature processing of stabilized compositions.
This stabilizer and its 5-chloro analog exhibit great resistance to volatilization, enhanced solubility in selected solvents, desirable absorption characteristics in the ultraviolet range and photographic inertness. This combination of properties makes these benzotriazoles particularly useful in photographic compositions especially in protecting color dye images against the harmful effects of ultraviolet light.
