Abstract
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.
