DIFFUSELY-REFLECTING POLARISER AND METHOD OF MAKING SAME

摘要

A process for making a diffusely reflecting polarizer comprises the steps of arranging polymeric fibers containing certain discontinuous phase birefringent fibrils and forming a solid film. The fibers are dispersed in a polymeric continuous phase, and are arranged in a substantially parallel array. A diffusely- reflective polarizer employs the film to effect polarization.
