Abstract

This invention relates to a polarizing film obtained by stretching a polyvinyl alcoholic resin film containing iodine, idoinized compound, cross-linking agent and/or water-proofing agent, then processing with a solution containing an inorganic acid or the salt thereof and/or an organic acid of 0.0001-5.0 wt% excluding boric acid, preferably a solution having pH in the range 2 ≤ pH ≤ 5, more preferably a solution having pH in the rang 2.2 ≤ pH ≤ 5. The polarizing film is excellent in wet heat durability with small reduce in polarizing property under examination of wet heat durability, in a more preferable aspect, the obtained polarizing film is also excellent in dry heat durability.
