Abstract
PURPOSE: To provide sufficient contrast, ray transmittance and degree of polarization to the extent of being usable for display as well by adsorbing and orienting dichromatic dyes together with iodine on and to a polyvinyl alcohol base film.
CONSTITUTION: Iodine and dichromatic dyes are compounded referably at ratios of 1:7 to 13 based on weight and are dissolved together with dye assistants such as KI, boric acid and other and crosslinking agents in water. The polyvinyl alcohol base film of more than 20 mole% in vinyl alcohol content such as the ethylene-vinyl alcohol copolymer film comprising saponifying an ethylene-vinyl acetate copolymer to preferably 85% or higher to have 20 mole% or over of vinyl alcohol content is dipped in the abovementioned dye bath and is thermally oriented.
