  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.

  2-[2-羟基-3,5-二叔丁基苯基]-2H-苯并三唑表现出在保护有机基质免受光诱导劣化方面的杰出功效，以及在稳定组分的高温加工过程中具有良好的抗挥发或渗出性能。这种稳定剂及其5-氯代衍生物具有极强的抗挥发性，增强了在选定溶剂中的溶解性，在紫外光范围内具有理想的吸收特性和摄影惰性。这些性质的结合使得这些苯并三唑在摄影组合物中特别有用，尤其是在保护彩色染料图像免受紫外光的有害影响方面。
