1. A multilayer film comprising:
- a norbornene-based cyclic olefin layer; and
a layer attached to the norbornene-based cyclic olefin layer, wherein the layer is formed from a curable material, wherein the layer exhibits a level of adhesion to the norbornene-based cyclic olefin layer greater than or equal to 1B as determined by ASTM D3359-02, and wherein the layer has a structured surface.

Abstract
A norbornene-based cyclic olefin layer with a curable layer disposed thereon is described. The curable layer may additionally be imparted with a texture. The norbornene-based cyclic olefin films with curable layers can be incorporated into optical bodies which include an optical film, such as an oriented multilayer optical film. In addition, the invention includes a method of coating a curable layer onto a norbornene-based polymer layer or film without requiring a primer layer. Methods of making the norbornene-based cyclic olefin layer containing films are also disclosed.
