BIAXIALLY ORIENTED POLYESTER FILM FOR HARD COAT |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a biaxially oriented polyester film for a hard coat of high flatness after hard coat-processing. SOLUTION: The coefficient of thermal expansion in the widthwise, direction at 50-100 deg.C in relation to 30 deg.C of the biaxially oriented polyester film is -0.5-0.5%, and the film satisfies formula 1: 10μm<R<500μm and formula 2:▵R/R<0.05 (R is the thickness of the film;▵R is the dispersion of the film thickness). |
