Abstract
A polarizer including an oriented polymeric first layer is described. The oriented polymeric first layer is preparable from a mixture of polyvinyl alcohol and crosslinker where the crosslinker is included in the mixture at 5 to 40 percent by weight based on the total weight of the polyvinyl alcohol and crosslinker. The oriented polymeric first layer is a substantially uniaxially drawn layer, in that for U=(1/MDDR−1)/(TDDR−1), U is at least 0.85, with MDDR being a machine direction draw ratio and TDDR being a transverse direction draw ratio.
