| titleOfInvention | Composite polyester film for magnetic recording media |
| abstract | PROBLEM TO BE SOLVED: To be excellent as a base film of a magnetic recording medium for a high-speed duplicator, which is excellent in film winding property, abrasion resistance and running durability and can be manufactured at low cost. A composite polyester film is provided. The invention relates to a composite film having a coating layer on one surface of the biaxially oriented polyester film, 0.00 average grain size d A is 0.8~1.6μm crosslinked polymer particles A 1 to 0.03% by weight, average particle diameter d B is 0.4~0.8μ The inert particles B which is m 0.1 to 0.8 wt%, inert inorganic particles C that further average particle diameter d C is the a and Mohs hardness 0.01~0.3μm less than 7 0.05 To 1.0% by weight, and the ratio of the average particle size of the particles A and B is expressed by the formula (1). And the three-dimensional ten-point average roughness SRz of the film surface A composite polyester film for a magnetic recording medium, wherein the ratio of the three-dimensional center plane average roughness SRa satisfies the expression (2). 1.5 ≦ d A / d B ≦ 3 (1) SRz / SRa ≧ 20 (2) |
