摘要： A polarizing film which comprises a polyvinyl alcohol-based resin film and iodine being adsorbed thereon and oriented, and is prepared, for example, by subjecting the polyvinyl alcohol-based resin film to a dyeing treatment, to a stretching treatment, to a boric acid treatment and further to a complementary color treatment in which the film is immersed in a solution containing a chlorinated compound. The polarizing film is so adjusted as to have a boric acid content of 5 to 40 weight % by the dyeing treatment, stretching treatment and boric acid treatment, and also to have a chlorine ion content of 200 to 10,000 ppm by the complementary color treatment. The above polarizing film retains an achromatic hue when it is arranged at a parallel Nicol position, and also exhibits improved durability of its optical characteristics under a high temperature and high humidity condition, and a high temperature condition.
