The manufacturing method of optical film |
| abstract |
The present invention relates to the manufacturing methods of optical film, this method is that the rubber cement as the material solution of optical film is cast on supporter in solution cast film formation, wet film (casting films) are formed on supporter, and wet film is removed the method that manufactures optical film from the supporter, it is characterized in that, by rubber cement from curtain coating mould curtain coating when supporter, casting and stretching ratio shown in following formula (1) is 3~6.Formula (1) casting and stretching ratio=supporter speed/ejection flow velocity. |
