摘要：
A cellulose acylate film manufacturing method based on melt-casting film formation technique, the comprising steps of: extruding a cellulose acylate film from a casting die, and sandwiching the cellulose acylate film between an elastically deformable touch roll and a cooling roll, wherein the cellulose acylate film includes at least one kind of compounds expressed by the following general formula (1) and at least one kind of phosphoric acid compounds selected from among phosphite, phosphonite, phosphinite and phosphane, wherein R11 through R16 each indicate a hydrogen atom or substituents.
