Abstract
A method of making embossed optical polymer films and embossed optical polymer films made are described. The embossed optical polymer films have substantially the same optical properties as unembossed optical polymer films. The method includes providing an optical polymer film having first and second major surfaces, softening at least one of the first and second major surfaces to produce a softened surface, embossing the softened surface to produce an embossed optical polymer film, and cooling the embossed optical polymer film.
