| titleOfInvention | Biaxially oriented polyester film for magnetic recording media |
| abstract | (57) [Summary] [Object] To provide a biaxially oriented polyester film for a magnetic recording medium, which is excellent in surface flatness and abrasion resistance. A biaxially oriented polyester film for a magnetic recording medium, wherein (A) the distribution curve of the projections on the film has a specific relationship, and (B) the number of projections of one ring or more by a Tl monochromatic light multiple interference reflection microscope. Is less than 1 piece / 10 cm 2 , and (C) the projections have a particle size ratio (major axis / minor axis) of 1.5 to 10 in the film, and an average particle diameter of an area circle equivalent diameter of 0.4. -1.0 μm and spindle-like calcium carbonate particles having a relative standard deviation of 0.5 or less 0.001-0.1 0% by weight, a specific surface area of 50 to 120 m 2 / g, a total pore volume of 0.5 to 1.0 ml / g, and an average particle diameter of 0.02 to 0.30 μm, aluminum oxide or silicon oxide. And one or more fine particles of titanium oxide 0.05-1. It is characterized in that it is formed by containing 0% by weight. |
