Abstract: A polarizer stack including an absorbing polarizer and a multilayer polymeric reflective polarizer bonded together is described. The absorbing polarizer has a first block axis and the reflective polarizer has a second block axis substantially parallel to the first block axis. The reflective polarizer has a shrinkage in a range of 0.4 percent to 3 percent along the second block axis when the reflective polarizer is heated at 95° C. for 40 minutes.

Abstract: Optical bodies are disclosed that include an optical film and at least one rough strippable skin layer. The at least one rough strippable skin layer can include a continuous phase and a disperse phase. In some embodiments, 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. Methods of making such exemplary optical bodies are also disclosed.
