Abstract
PURPOSE: To obtain a polarizing film having superior light resistance and stable performance by sticking a water soluble ultraviolet absorber to a polarizing film itself to provide ≤400mμ light absorbing characteristics.
CONSTITUTION: A water soluble ultraviolet absorber such as 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid or a water soluble fluorescent dye such as a stilbene type fluorescent dye based on sodium 4,4'-diaminostilbene-2,2'-disulfonate is dissolved in an aqueous soln. contg. iodine or dye. A polyvinyl alcohol film is dipped in the mixed aqueous soln. and drawn about 2.5W3.7 times in one direction to obtain a polarizing film. The amount of the absorber or fluorescent dye is preferably about 0.003W0.01wt% to the amount of the polymer substrate.
