| titleOfInvention | Manufacturing method of optical film |
| abstract | An object of the present invention is to provide an optical film manufacturing method capable of eliminating uneven defects generated on the film surface when producing a film by a melt extrusion method, and having few retardation unevenness defects obtained by stretching the film. To do. An amorphous thermoplastic resin extruded from a T die in a method of producing an optical film by bringing an amorphous thermoplastic resin film extruded from a T die into contact with a cooling roll and then stretching. The temperature of the cooling roll with which the film first contacts is T1 (° C.), the preheating temperature before stretching of the film is T2 (° C.), the temperature during stretching of the film is T3 (° C.), and the glass of the amorphous thermoplastic resin film When the transition temperature is Tg (° C.), T2 is set to a temperature that is at least 10 ° C. higher than T1, at least 10 ° C. higher than Tg, and higher than T3.
