Abstract

The present invention relates to a method for producing polarizer, and more specifically relates to a method capable of producing a polarizer with smallest change in hue even if the polarizer has been exposed to high temperature for a long time, which comprises steps of swelling, dyeing, cross-linking, complementary-coloring and first stretching to a polarizer forming film; wherein the swelling step, the dyeing step, the cross-linking step and the complementary-coloring step are performed in this order, and the first stretching step is performed before the complementary-coloring step, wherein the polarizer forming film is subjected to a second stretching at a stretch ratio of 1.010 to 1.100 in the complementary-coloring step.
