Abstract
Optical films and processes for forming the optical films are described in which materials having different properties are used and the different properties are exploited to obtain improved optical and/or mechanical properties of the optical film. The different properties of the materials may be used to select processing conditions under which the materials will react differently. The film may be processed with respect to two different directions with the amount of molecular orientation, if any, induced by the process being separately controlled for each material and each direction.
