Abstract
An optical information medium providing a protective layer above an optically transparent substrate to protect a recording part, and can record information which is optically readable by means of laser beam. An aqueous printing ink-fixable, hydrophilic resin film is formed on the protective layer. Given letters and patterns can be printed easily and satisfactorily. Such letters and patterns are printable by means of, for example, an ink jet printer.
Claims15
An optical information medium which comprises a protective layer formed of a UV-curable resin film on a substrate, an intermediate layer formed between the substrate and the protective layer for storing information therein and a printing layer formed of a hydrophilic resin film on said protective layer, characterized in that the hydrophilic resin film is closely adhered to the protective layer, wherein bonding properties at a boundary between the hydrophilic resin film and the protective layer are better than bonding properties at a boundary between the intermediate layer and the protective layer.
