摘要： The present invention is an aromatic polyamide film, which is a laminated film consisting of at least two layers, comprising an aromatic polyamide and 0.1 wt% to 10 wt% of at least one or more different polymers, being contained at least in the outermost layer (layer A) of the film, subject to the condition that the following formulae are satisfied where d is the thickness of the layer A ( mu m); t, the circle equivalent diameter of the isles of the different polymer ( mu m); L, the major axis of the isles ( mu m); and s, the minor axis of the isles ( mu m). The aromatic polyamide film of the present invention is especially useful as a base film of a magnetic recording medium with high productivity since it is free from the wrinkling and weaving caused at the time of film winding and excellent in abrasion resistance on the film surface.

摘要： A film and a magnetic-recording medium using the film, where the heat contraction ratio in the width direction of the film subjected to thermal treatment under no-tension for 30 min. at 180°C is from 1.0 to 2.5%, and where the film satisfies the following expressions (1-4) simultaneously, with αMD(× 10-6/°C) and αTD(× 10-6/°C) being thermal expansion factors in the length and the width direction, respectively, βMD(× 10-6/%RH) and βTD(× 10-6/%RH) being humidity expansion factors in the length and the width direction, respectively. Dimensional changes in the film by temperature and humidity are specified in a specific range, and this enables the difference in dimensional changes between the length and the width direction of the film used as a magnetic recording medium to be extremely small. -10≤αMD≤10 (1) αMD-10≤αTD≤αMD-3 (2) -10≤βMD≤10 (3) βMD-10≤βTD≤βMD-3 (4)
