摘要： Optical bodies are disclosed that include a first optical film, a second optical film and at least one rough strippable boundary layer disposed between the first and second optical films. Also disclosed are optical bodies including a strippable boundary layer disposed between the first and second optical films and including a first polymer and a second polymer that is substantially immiscible in the first polymer. The present disclosure also provides methods of processing optical bodies that include stretching the optical bodies.
