Biaxially oriented laminated polyester film for magnetic recording media |
| abstract |
(57) [Summary] (Corrected) [Objective] To provide a biaxially oriented polyester film for magnetic recording, which is excellent in light-shielding property, slit property and running durability. [Structure] Moose hardness is 7 or more, and average particle size is 0. The polyester (A) layer containing the inorganic particles (a) of 005 to 0.5 μm and the average particle size of the aggregate are 0.005 to A film formed by laminating a polyester (B) layer containing 0.5 μm carbon black particles (b), A biaxially oriented laminated polyester film for a magnetic recording medium which simultaneously satisfies specific conditions. |
