    摘要: Disclosed is a biaxially oriented laminated film comprising a film layer B whose major component is a thermoplastic resin B.sub.r, a thin film layer A laminated on at least one surface of the film layer B and whose major components are a thermoplastic resin A.sub.r and particles with a specified mean diameter contained therein at a specified content, and a skin layer C laminated on at least one surface of the laminated film layer A and film layer B and having a thickness of 1-300 nm. The particles form the desired protrusions on the film surface and the skin layer C can have various properties such as a good adhesive property with a magnetic layer, a good adhesive property with an ink or a good antistatic property without injuring the good scratch resistance, chipping resistance, chromatic S/N, etc., achieved by the desired protrusions formed by the particles.

    摘要: Disclosed is a biaxially oriented laminated film with excellent scratch resistance and friction property, as well as excellent dubbing resistance when used as a base film of magnetic recording media. The biaxially oriented laminated film comprises a first layer containing a first thermoplastic resin as a major constituent; and a second layer containing a second thermoplastic resin as a major constituent, which is formed on at least one surface of the first layer. The second layer contains inert particles with an average diameter of 0.1 to 10 times the thickness of the second layer, and the content of the inert particles in the second layer is 0.5-50% by weight. The thickness of the second layer is 0.005-3 .mu.m.
