Description
一方、二色性色素として二色性有機染料を用いる場合は、通常、水溶性の二色性有機染料を含む水溶液に、ポリビニルアルコール系樹脂フィルムを浸漬して染色する方法が採用される。この水溶液における二色性有機染料の含有量は通常、水１００重量部あたり１×１０ −３ 〜１×１０ −２ 重量部程度である。この水溶液は、硫酸ナトリウムなどの無機塩を含有していてもよい。この水溶液の温度は、通常２０〜８０℃程度であり、また、この水溶液への浸漬時間（染色時間）は、通常３０〜３００秒程度である。 On the other hand, when a dichroic organic dye is used as the dichroic dye, a method of immersing and dyeing a polyvinyl alcohol-based resin film in an aqueous solution containing a water-soluble dichroic organic dye is usually employed. The content of the dichroic organic dye in this aqueous solution is usually about 1 × 10 −3 to 1 × 10 −2 parts by weight per 100 parts by weight of water. This aqueous solution may contain an inorganic salt such as sodium sulfate. The temperature of this aqueous solution is usually about 20 to 80 ° C., and the immersion time (dyeing time) in this aqueous solution is usually about 30 to 300 seconds.
積層光学部材においては、偏光板以外の光学層として位相差フィルムを含むものが、液晶表示装置に適用したときに有効に光学補償を行えることから、好ましく用いられる。位相差フィルムの位相差値（面内および厚み方向）は、適用される液晶セルに応じて、最適なものを選べばよい。 In the laminated optical member, those including a retardation film as an optical layer other than the polarizing plate are preferably used because optical compensation can be effectively performed when applied to a liquid crystal display device. The optimum retardation value (in-plane and thickness direction) of the retardation film may be selected according to the applied liquid crystal cell.
