| titleOfInvention | Method for producing optical film |
| abstract | The present invention relates to a process for producing a sequential biaxially stretched film for optical use, and provides a method for producing an optical film that does not cause peeling unevenness in the film width direction that occurs during roll longitudinal stretching. A film manufacturing method according to the present invention is used when longitudinally stretching a film 5 made of a thermoplastic resin by two stretching rolls 1 and 2 arranged at a distance from each other. It is. Here, the nip rolls 3 and 4 are disposed so that the sandwiching portion 6 is an end portion on the contact region 8 stretching roll 2 side and the sandwiching portion 7 is an end portion on the stretching roll 1 side of the contact region 9. . In this way, the contact time t between the film and the stretching roll 1 when stretching the film 5 is 0.5 seconds <t <2.5 seconds, and the surface temperature T of the stretching roll 1 is the film Tg-6 ° C. < The roll is stretched longitudinally with T <film Tg.
