<p>A process for the manufacture of PL polarizers that exhibit a high dichroic ratio in absorption, and which preferably have been produced by applying minimal mechanical deformation is disclosed. The invention also discloses a process for the manufacture of PL polarizers that exhibit a high dichroic ratio in absorption and emission, and which preferably have been produced by applying minimal mechanical deformation. The process comprises the steps of a) providing a blend comprising at least one photoluminescent dye and at least one carrier polymer by melt-mixing, and b) melt-processing said blend into a body having a first shape, and c) anisotropically distorting the first shape of the body to yield said photoluminescent polarizer.</p> |
