Optical film manufacturing method |
| abstract |
The present invention provides a method for manufacturing an optical film. The method uses (meth)acrylic resin or cycloolefin resin as the raw material resin. When it is dissolved by a solvent, it does not cause dissolution problems such as gnocchi. Improve the productivity, even if it is a thin film and the production speed is increased to produce the film, there will be no problems with the surface quality of the produced film, especially the unevenness of the film thickness. The present invention is a method for manufacturing an optical film containing a specific resin. It includes a crushing step of crushing the recycled material generated in the optical film manufacturing step to obtain a crushed product with a bulk density of 0.05 to 0.20 g/cm 3. The compression step of compressing with a compression ratio of ~7 times, the raw material including the compressed product obtained in the aforementioned compression step is dissolved in a solvent, and the dope preparation step is performed, and the dope preparation step is obtained from the aforementioned dope preparation step. After the dope is cast on the support, it is dried and peeled off to obtain a film. |
