| 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 satisfiedwhere d is the thickness of the layer A (mum); t, the circle equivalent diameter of the isles of the different polymer (mum); L, the major axis of the isles (mum); and s, the minor axis of the isles (mum). The aromatic polyamide film of the present invention is especially useful an 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.
