  • Optical recording medium and method for conducting recording on said medium
    Patent number: 4873178
    Abstract: An optical recording medium is provided which comprises a substrate and a colored film formed by electrolytic polymerization on the substrate. The film may be formed on an electroconductive substrate, or it may be transferred onto a non-electroconductive substrates. A method for recording employing the electrolytically polymerized film is also provided.
