TLDR
In this article, a magnetic recording medium which excels in the adhesive strength between the base material and the ferromagnetic thin metallic film was obtained by using an organic high molecular material with the reducing deposition control function provided on the surface for the base materials.Abstract:
PURPOSE:To obtain a magnetic recording medium which excels in the adhesive strength between the base material and the ferromagnetic thin metallic film, by using an organic high molecular material with the reducing deposition control function provided on the surface for the base material. CONSTITUTION:An organic compound having the oxidation-reduction potential in a range from -1.0V to +0.5V such as the azo compound, anthraquinone compound, xanthene compound, azine compound, tiazine compound, oxazine compound, indigo compound, thioindigo compound, triphenylmethane compound and the like is provided on a thermosetting or thermoplastic synthetic high molecular material. Then, a ferromagnetic thin metallic film is provided by an electroless plating method to obtain a magnetic recording medium.read more
