| titleOfInvention | Method for producing retardation film |
| abstract | A method for producing a polypropylene resin retardation film having high axial accuracy and a uniform retardation value is provided. SOLUTION: A raw film made of a polypropylene resin, (A) a step of longitudinal stretching, (B) a step of curing in an environment at a temperature T ° C between 0 to 40 ° C, and (C) The transverse stretching step is performed in this order, and the curing step (B) is performed so as to satisfy the formula: D ≧ −0.4T + 20, where the curing period is D days, and the polypropylene-based resin phase difference film is formed. A method of manufacturing is provided. Typically, for a raw film made of a polypropylene-based resin, (A) a longitudinal stretching step, (B) a step of curing for 10 days or more in an environment at a temperature of 20 to 30 ° C., and (C) lateral A retardation film is manufactured by performing the stretching process in this order.
