DIFFUSELY-REFLECTING POLARIZER HAVING NEARLY ISOTROPIC CONTINUOUS PHASE
摘要
The present invention provides a diffusely-reflecting polarizer comprising: a first polymer which is amorphous and having a birefringence of less than about 0.02 and a second polymer, the first polymer being a continuous phase, and the second polymer being a disperse phase whose index of refraction differs from said continuous phase by greater than about 0.05 along a first axis and by less than about 0.05 along a second axis orthogonal to said first axis; wherein the diffuse-reflectivity of said first and second polymers taken together along at least one axis for at least one polarization state of electromagnetic radiation is at least about 50%, the diffuse transmittance of said first and second polymers taken together along at least one axis for at least one polarization state of electromagnetic radiation is at least about 50%.
