<P>PROBLEM TO BE SOLVED: To provide a cellulose acylate film low in optical anisotropy and reduced in the change of optical characteristics caused by heat and humidity. <P>SOLUTION: This cellulose acylate film is manufactured by a manufacturing method having a process for preparing a dope liquid by dissolving cellulose acylate and additives, a process for casting the obtained dope liquid, a process for peeling the formed film and a process for drying the peeled film and characterized in that a drying temperature in the drying process is not lower than the glass transition temperature of cellulose acylate. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
