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.
