摘要: The effect of some added antioxidants on the photodegradation C.I. Solvent Yellow 33 (quinophthalone) and Direct Red 39 in cellulose acetate films have been investigated. effects varied according to antioxidant type. For example, addition 2, 6-di-t-butyl-4-methylphenol, an effective radical scavenger, afforded little protection against photodegradation, while singlet oxygen quenching such as nickel bis(dithiobenzil), dialkyldithiocarbamate, bis(mesitylenesulphonate) conferred improved resistance dyes towards photodegradation.
