An optical film comprising a first layer and an easy-adhesive layer provided on at least one side of the first layer, the first layer being a layer of crystalline resin, the crystalline resin comprising a polymer containing an alicyclic structure , And the aforementioned easy-to-bond layer is a layer of urethane resin. And a method for manufacturing an optical film, which comprises the following steps: step (1), forming a crystalline resin containing a polymer containing an alicyclic structure to obtain a crystalline resin film with a crystallinity of less than 3%, step (2) ), forming an easy-adhesive layer on the surface of the aforementioned crystalline resin film to obtain a multi-layer product comprising the aforementioned crystalline resin film and the aforementioned easy-adhesion layer, and step (4) to make the aforementioned crystallinity in the aforementioned multi-layer The resin film crystallizes. |
