PURPOSE:To improve the antistatic performance and scratching resistance of the optical information recording medium and to improve the corrosion resistance of a recording film or reflection film thereof by devising materials for a protective film thereof by devising material for a CONSTITUTION:The outside surface of one layer or multiple thin films 7 laminated on a substrate 1 are coated with the protective film 9 consisting of an electrically conductive material formed by doping an acid in polyaniline. The protective film 9 is formed by producing a liquid material formed by dissolving the polyaniline doped with the acid into N-methylpyrrolidone or a solvent mixture composed of the N-methylpyrrolidone and applying this liquid material by a suitable method, such as spin coating or dipping, on the outside surface of the thin films 7 formed on the substrate 1. |
