摘要: The present invention relates to a process for producing a cellulose acylate film, and an optical compensation sheet, a polarizing plate, and an image display device employing the cellulose acylate film. The process for producing a cellulose acylate film of the present invention is characterized by including a step of preparing a cellulose acylate solution containing 0.01 to 20 parts by weight of an aromatic compound having at least two aromatic rings relative to 100 parts by weight of a cellulose acylate, a step of casting, and a step of blowing a gas on the cast cellulose acylate solution at an effective wind speed of at least 10 m/min during a first half of drying prior to peel-off.
