をその両側に貼合して製造されている。Currently, dye-based polarizing films are made using stretched and oriented polyvinyl alcohol (hereinafter abbreviated as PVA) or its derivatives, or polyvinyl chloride (hereinafter abbreviated as PvC).
The process of dehydrochlorination of film is to produce polyene by dehydration of PVA film, adsorb dichroic dye to the oriented polyene film, and then produce cellulose such as cellulose triacetate, which has good optical transparency. It is manufactured by laminating film on both sides.

耐久性はいまひとつ不良である、等の問題点がある。The dye-based polarizing film thus obtained has (1)
The cellulose film used as the protective film, such as cellulose triacetate, is very expensive. (2) The price is high because it involves a post-process of laminating the polarizer and the protective film. (8) Triacetic acid Cellulose-based films such as cellulose have high water absorption and water vapor permeability, so it is difficult to maintain
There are problems such as the durability of the dye-based polarizing film, which is referred to as IS, at high temperatures and high humidity is rather poor.

減化ということには、それ程ならない。In order to improve some of these problems, for example, Japanese Patent Application Laid-Open No. 60-162222, Japanese Patent Application Laid-Open No. 60-1622
As seen in Japanese Patent No. 28, etc., there is a method in which a -axially stretched polyester film is used as a protective film for a polarizing film. Although the durability of dye-based polarizing films at high temperatures and high humidity is considerably improved compared to the case of using cellulose-based films, the durability of these polarizing films is limited because the base polymer is PVA. There is. Furthermore, since it includes a post-process of lamination, it does not significantly simplify the process or reduce the cost.
本発明の目的は、従来の染料系偏光フィルムがもつ以上

フィルムを提供することにある。An object of the present invention is to solve the above-mentioned problems of conventional dye-based polarizing films and to provide an extremely low-cost dye-based polarizing film.

を見いだし、本発明に至ったものである。[Means for solving the problems] The present invention is the result of repeated research in order to solve the above problems, and it is a PVA8 base polymer in which a dichroic dye is adsorbed and oriented. It appears as a conventional dye-based polarized film, not only in a high temperature state U (hereinafter, when this expression is used, it means 100''C), but also in a high temperature state (hereinafter, when this expression is used, 85°C x 90%R
The performance of the polarizing film does not change much even if it is left for a long time (meaning H), and it is very durable, and there is no post-process of laminating a protective film, so it is different from conventional dye-based polarizing films. It was discovered that it can be manufactured at an extremely low cost compared to ilms, leading to the present invention.
