Abstract
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.
