Title: Production of polarizing film excellent in durability
Inventor: TSUMURA YUSUKE
IPC: C08J5/18
Filed: 1996-02-09
Abstract: PURPOSE: To obtain a polarizing film excellent in durability by using a polyvinyl alcohol resin of a high polymn. degree and controlling the reduction rate of the film width to a specific range when the resin film is stretched. CONSTITUTION: At the time of forming a polyvinyl alcohol resin film having >=2600 average polymn. degree and uniaxially stretching it to obtain a polarizing film, the film is uniaxially stretched at least during the film is treated with a boron compd. and is uniaxially stretched in such a manner that the film width after stretching is <=60% of the film width before stretching. In a conventional method of uniaxial stretching of a polyvinyl alcohol film, shrinkage in the width direction of a film is prevented as much as possible from the viewpoint of productivity. However, by the present invention, shrinkage in the width direction is controlled to a specific range contrary to a conventional method. To stretch a film with the specific range, roll stretching or other method is used, and if roll stretching is used, one-step or multistep rolling can be used.
