A nonbinder type of magnetic recording medium is disclosed. The binder is comprised of a non-magnetic support having thereon, in sequence, a thin magnetic metal film laminated using the evaporation technique and a protecting film, with the thin magnetic metal film converted in its surface part alone to a metal oxide layer by being oxidized with oxygen plasma, to a metal nitride layer by being nitrided with nitrogen plasma or to a glow discharge-processed layer. The protecting film includes a high molecular weight compound, a higher fatty acid, a fatty acid ester or a combination thereof, laminated on the metal oxide layer, the metal nitride layer or the glow discharge-processed layer.

摘要:
A magnetic recording medium and a process for producing it is disclosed. The medium is comprised of a non-magnetic flexible support base and a magnetic layer formed on a surface of the support base. The magnetic layer is preferably in the form of a thin, ferromagnetic metal film formed by vapor deposition. An overcoat layer of a fluorine-containing organic material is formed directly on the magnetic layer. The fluorine content of the overcoat layer continuously and gradually decreases in the direction toward the magnetic layer. Accordingly, high fluorine content near the surface of the overcoat layer provides improved smoothness near the surface whereas the lower fluorine content near the interface of the overcoat with the magnetic layer allows for strong adhesion between the overcoat and the underlying magnetic layer substrate. The media is formed by providing the flexible support base, forming the magnetic layer on the surface of the support base and forming the overcoat layer on the magnetic layer by performing plasma polymerizations of a fluorine-free monomer gas and a fluorine-containing monomer gas with a time lag. The overcoat layer is formed such that the fluorine content continually increases in a direction away from the magnetic layer.

摘要:
In a liquid crystal display device including an orientation film and a seal material, at a terminal connection portion where one substrate extends outward from another substrate, a step portion of an organic insulating film is formed on an inner side of the seal material to dispose a step, whereby spreading of the orientation film from the step portion to the seal material is limited. Lead wires that electrically interconnect connection terminals and pixel portions are formed on a portion of the organic insulating film where the film thickness is thin.
