| titleOfInvention | Biaxially oriented polyester film |
| abstract | (57) [Summary] (Modifications) [Problem] To be excellent in slitting property at the time of film production and magnetic recording medium production, to be able to highly satisfy running property and electromagnetic conversion characteristics as a magnetic recording medium, and to prevent dropout occurrence. Provided is a film which is excellent in terms of the above and has extremely small generation of scratches and abrasion powder. SOLUTION: Crosslinked polymer particles having an average particle size of 0.8 to 1.5 μm, a particle size distribution value of 1.0 to 2.0, and a particle deformation of 1.5 to 5.0 are 0.001 to 0.05 weight by weight. %, Average particle size 0. 0.1 to 1.0% by weight of active fine particles of 2 to 0.6 μm, A biaxially oriented polyester film obtained by laminating a polyester A layer containing 0.1 to 1.0% by weight of inert fine particles having an average primary particle size of 0.3 μm or less and a Mohs hardness of 7 or more on a polyester B layer. Satisfies the following equation (E MD is the tensile elongation at break in the machine direction of the film, E TD is the elongation at break in the transverse direction, RMS is the root mean square roughness of the polyester A layer surface, SRa is the average surface roughness of the A layer surface (μm) , PV is the maximum roughness of the surface of layer A) |
