Biaxially oriented laminated film. |
摘要 |
<p>A biaxially oriented laminated film having at least three layers has excellent abrasion resistance and electromagnetic conversion property when the film is used as the base film of a magnetic recording media. The biaxially oriented laminated film comprises at least one outermost layer containing particles A, the particle density ratio at a surface layer of the particles A is not less than 0.01, and the mean primary particle size D of the particles A and the thickness T of the outermost layer containing the particles A satisfies the equation; D</= T</= 200D.</p> |
