    摘要: A laminated film for a super-high density magnetic recording medium, which comprises (A) a layer composed of a thermoplastic resin and (B) a layer of a thermoplastic resin containing fine particles therein. In this laminated film, the outer surface of the layer (A) has a surface roughness of less than 0.005.mu. as expressed as the Ra value, and the outer surface of the layer (B) has a surface roughness of 0.005 to 0.040.mu. as expressed as the Ra value. The outer surface of the layer (B) has either (i) a plurality of depressions and a plurality of protrusions, which are formed thereon in a configuration such that at least one protrusion exists within each depression or at least one protrusion exists in the area where two or more depressions are contiguous to each other, or (ii) protrusions on a flat plane and a covering layer (C) composed of a lubricant, which is formed on the surface of the layer (B). This covering layer (C) may be formed on the surface having the above-mentioned depressions and protrusions. The covering layer (C) is a continuous film layer or a discontinuous film layer formed of worm-like nodules. When a ferromagnetic metal thin film is formed on the surface of the layer (A) by vacuum evaporation and a protective film layer is formed on this thin film, there is obtained a vacuum-deposited video tape excellent in running properties and electromagnetic transformation performance. In this vacuum-deposited video tape, the transfer of the surface configuration due to the coarseness of the running surface can be prevented.

    摘要: A super high density magnetic recording medium is provided, which comprises a polyester film and a discontinuous film formed on at least one surface of the polyester film. The discontinuous film has a thickness of smaller than 500 angstroms and is composed mainly of a water-soluble polymer, a silane coupling agent, and if desired, a silicone resin. A high density magnetic recording medium is also provided, which comprises a ferromagnetic metal thin film formed on the discontinuous film layer of the polyester base film. The polyester base film is especially suitable for formation of a metallized video tape, and this tape is excellent in the slip characteristics and abrasion resistance and advantageous in that noises and drop-out are reduced.

    摘要: A polyester which is prepared by using a germanium compound as the polymerization catalyst, in which the Young's modulus E.sub.MD in the machine direction and the Young's modulus E.sub.TD in the transverse direction satisfy the requirements of E.sub.MD .gtoreq.350 kg/mm.sup.2, E.sub.TD .gtoreq.350 km/mm.sup.2 and E.sub.MD .times.E.sub.TD .gtoreq.250,000 kg.sup.2 /mm.sup.4, the refractive index n.sub.ZD in the thickness direction satisfies the requirement of 1.480.gtoreq.n.sub.ZD .gtoreq.1.492, and the maximum roughness Rt of at least one surface satisfies the requirement of Rt.gtoreq.100 nm, is valuable as a base film for a magnetic recording medium. A laminate structure of a polyester layer A and a polyester layer B is also used as a base film for a magnetic recording medium, in which the above requirements of E.sub.MD, E.sub.tD and n.sub.ZD are satisified, fine particles are incorporated in the layer B, the outer surface of the layer A satisfies the requirement of Rt .gtoreq.100 nm and Rt of the outer surface of the layer B is in the range of from 30 to 150 nm. A magnetic recording medium having a ferromagnetic metal thin film formed thereon, which is prepared by using this polyester film has a good processability at the preparation and shows a reduced drop-out, and this magnetic recording medium is scratched only to a negligible extent by contact with a magnetic head and does not damage the magnetic head.

    摘要: A die plate for a die block can have a coat-hanger-shaped flow path for extruding a molten foamable thermoplastic resin in a form of a sheet. The die plate can be on a downstream side of the coat-hanger-shaped flow path to make a flow rate of the molten foamable thermoplastic resin uniform in a width direction. The die plate can have a multiplicity of delivery apertures. The delivery apertures in opposite side regions can have a diameter greater than a diameter which the delivery apertures in a center region have. A die unit can include a die block, which has a multiple bifurcated manifold terminating in plural coat-hanger-shaped flow paths at downward ends thereof, and a like plural number of similar die plates as described above. A process for producing a wide thermoplastic resin foam can use the die unit.
