WO/2006/129685 is referenced by 6 patents.

There is provided a method for producing a thermoplastic film that has a small distribution of retardation and excels in optical properties. In the method for producing a thermoplastic film by after extruding a molten resin from a die into a sheet, and cooling and solidifying the extruded sheet on a rotating cooling drum, peeling the cellulose acylate film off the cooling drum, and taking off the film with a take-off roller, the tension of the cellulose acylate film at the take-off roller is set to 0.02 kgf/mm2 or lower.
