A formazan metal complex dye is contained as a light absorbing dye in a recording layer to construct an optical recording medium. The formazan metal complex dye has high solubility and a relatively low thermal decomposition temperature and the recording medium exhibits high sensitivity, especially high recording sensitivity, and improved light resistance. The formazan metal complex dye can be used as a photo-stabilizer in an optical recording medium. The formazan metal complex dye is also effective for stabilizing conventional dyes against light.
在记录层中含有一种甲臢金属络合染料作为光吸收染料,以构建一种光学记录介质。甲臢金属络合染料具有高溶解度和相对较低的热分解温度,记录介质具有高灵敏度,特别是高记录灵敏度,以及更好的耐光性。甲臢金属络合染料可用作光学记录介质中的光稳定剂。甲臢金属络合染料还能有效地稳定传统染料的耐光性。
