METHOD FOR PRODUCING CELLULOSE ACYLATE FILM AND OPTICAL COMPENSATION FILM FOR LIQUID CRYSTAL DISPLAY PLATE PRODUCED BY USING THE METHOD |
摘要 |
According to the present invention, a cellulose acylate film having high thickness precision and no streaks can be formed by producing a film with a cellulose acylate resin by means of the polishing roller method, and a high-performance optical film, which is free from the retardation distribution, can be produced by subsequently stretching the cellulose acylate film thus obtained within a magnification range from 1 or more and 2.5 or less.
