    摘要： Optical bodies are disclosed that include an optical film and at least one rough strippable skin layer operatively connected to a surface of the optical film. The at least one rough strippable skin layer can include a continuous phase and a disperse phase. Alternatively, the at least one rough strippable skin layer can include a first polymer, a second polymer different from the first polymer and an additional material that is substantially immiscible in at least one of the first and second polymers. In some exemplary embodiments, a surface of the at least one rough strippable skin layer adjacent to the optical film comprises a plurality of protrusions and the adjacent surface of the optical film comprises a plurality of asymmetric depressions substantially corresponding to said plurality of protrusions. In addition, optical bodies are disclosed that include an optical film having a surface with asymmetric depressions, the asymmetric depressions having a major dimension substantially collinear with a major axis of the optical film and a minor direction substantially collinear with a minor axis of the optical film. Methods of making such exemplary optical bodies are also disclosed.

    摘要： A process for making an optical film includes stretching a polyolefin film in a first direction and stretching the polyolefin film in a second direction different than the first direction forming a biaxially stretched polyolefin film. At least a portion of the stretching of the polyolefin film in the second direction occurs simultaneous with the stretching of the polyolefin film in the first direction. The biaxially stretched polyolefin film has a length and a width and substantially non-absorbing and non-scattering for at least one polarization state of visible light. The biaxially stretched polyolefin film has x, y, and z orthogonal indices of refraction where at least two of the orthogonal indices of refraction are not equal, an in-plane retardance being 100 nm or less and an out-of-plane retardance being 50 nm or greater.
