Abstract

Optical recording media using mixtures of benzoindolenic trimethine cyanine dyes, where the first benzoindolenic trimethine cyanine dye bears a heterocyclic azo dye metal complex as the counterion and the second benzoindolenic trimethine cyanine dye has a different type of counterion. This combination of these benzoindolenic trimethine cyanine dyes coated on a substrate results in high density media, where the dyes have a high solubility and heat resistance.
