Biaxially oriented polyester film |
| abstract |
(57) [Summary] [Constitution] The intrinsic viscosity [η] is 0.7 to 3.0 (dl / g) the polyester, the breaking elongation A is 200% or less, and the relationship between the breaking elongation A (%) and the elastic modulus B (kg / mm 2 ) satisfies the following formula (1). Axial oriented polyester film. B ≧ -1110 × log (A) +2850 (1) [Effect] A biaxially oriented polyester having a high elastic modulus and excellent surface flatness, which is suitable as a base film for magnetic tape for long-term recording. the film. |
