Abstract:
A method for producing a cellulose acylate film containing an additive comprising an aliphatic compound, the method contains a process of thermal shrinkage treatment at an atmospheric temperature higher than the glass transition temperature (Tg) in the state where at least one of the transverse direction and the machine direction of the film is free, and a cellulose acylate film obtained by the above method.
