| titleOfInvention | Method for producing retardation film |
| abstract | An original film 5 made of thermoplastic resin is caused to travel in one direction between a pair of primary nip rolls 1A and 1B and a pair of secondary nip rolls 2A and 2B which are spaced apart and have different peripheral speeds. However, the present invention provides a method for producing a retardation film, wherein the smoothness is enhanced as much as possible by longitudinally uniaxially stretching, and color unevenness can be suppressed or prevented. SOLUTION: Between a primary side nip roll 1A, 1B and a secondary side nip roll 2A, 2B, a preheating region 6 and a stretching region 7 in which the glass transition temperature Tg to Tg + 10 ° C. of the film is sequentially applied from the upstream side in the film running direction. A cooling region 8 having a glass transition temperature Tg-10 ° C. to Tg-50 ° C. of the film is provided, and two or more films having a surface temperature lower than the glass transition temperature Tg are formed in the cooling region. Cooling while sequentially supporting with pass rolls. [Selection figure] None |
