Master film for producing optical film |
| abstract |
(Task) To provide a raw film for optical film production that can easily produce an optical film having low shrinkage stress excellent in both optical properties, color, and durability, and a method for producing an optical film using the same. (Solving means) A master film for producing an optical film containing a hydroxymethyl group-containing vinyl alcohol-based polymer having a content of the structural unit represented by the following formula (1) in a range of 0.1 to 1.9 mol%; And a manufacturing method having a step of uniaxially stretching as a manufacturing method of an optical film using the original film for manufacturing the optical film. [In the formula, R 1 represents an alkyl group having 1 to 3 carbon atoms] |
