| titleOfInvention | Polarizing film and its manufacturing method |
| abstract | In the production method of a polarizing film which performs at least a swelling process, a dyeing process, a 1st crosslinking extending process, and a 2nd crosslinking extending process in this order about a polyvinyl alcohol film; The average degree of polymerization of polyvinyl alcohol contained in the polyvinyl alcohol film is 2500 to 3500; In the first crosslinking stretching step, in an aqueous solution of 40 to 55°C containing 1 to 5% by mass of boric acid, uniaxial stretching so that the stretching ratio during the step is 1.1 to 1.3 times and the total draw ratio is 2.5 to 3.5 times and ; In the second crosslinking stretching step, in an aqueous solution of 60 to 70°C containing 1 to 5% by mass of boric acid, uniaxial stretching so that the draw ratio during the step is 1.8 to 3.0 times and the total draw ratio becomes 6 to 8 times do. Thereby, a polarizing film having excellent polarization performance and low shrinkage stress can be produced. |
