PROBLEM TO BE SOLVED: To provide a method for thermally embossing an optical polymer film without deteriorating optical properties and at a higher speed, and an embossed optical polymer film produced by this method. I do. An optical polymer film having a first major surface and a second major surface is provided, and at least one of the first major surface and the second major surface is softened to reduce the softened surface. Forming, embossing the softened surface to produce an embossed optical polymer film, and a method for producing an embossed optical polymer film, comprising: cooling the embossed optical polymer film, Further, the present invention relates to an embossed optical film produced by this production method. |
