ABSTRACT:
Disclosed is a biaxially oriented thermoplastic resin film formed by laminating a layer A composed of a thermoplastic resin A containing particles on at least one surface of a layer B composed of a thermoplastic resin B. The film has a specified ratio t/d of the thickness of the layer A "t" to the mean diameter of the particles contained in the thermoplastic resin A "d", a specified number of protrusions having a diameter of not less than 0.7 .mu.m and not more than 2.6 .mu.m among protrusions existing on the surface of the layer A and a specified ratio L/S of a number S of protrusions having a smaller diameter to the number L of protrusions having a diameter in the above range. An excellent winding property when the film is wound and an excellent dubbing resistance when the film is used for a video tape can be obtained.
