＜剛軟性試験＞
安田精機製作所製のＮｏ．４７６のカンチレバー型柔軟度試験機を用いる。また、本試験では静電気の影響を排除するため、試験に用いるフレキシブル偏光膜等を適切に除電して行った。
５０ｍｍ（吸収軸方向）×１５０ｍｍ（透過軸方向）の矩形物（フレキシブル偏光膜）を、頂部が平面（５０ｍｍ×１５０ｍｍ：フレキシブル偏光膜と同じサイズ）で、長辺の一端に４５°の斜面を持ち、断面が台形の滑らかなＳＵＳ板台４１の頂面に、収まるように設置する。フレキシブル偏光膜の設置は透過軸方向に斜面があるように行った。
前記フレキシブル偏光膜を、押し出し速度１０ｍｍ／ｓｅｃで、斜面側に静かに滑らせ移動させる（１）。フレキシブル偏光膜の先端が斜面に初めて接した箇所でフレキシブル偏光膜の移動を止めた（２）。頂部が平面においてサンプルが移動した距離Ｌ（ｍｍ）を測定する。
５０ｍｍ（透過軸方向）×１５０ｍｍ（吸収軸方向）の矩形物（フレキシブル偏光膜）について、前記同様の操作（但し、フレキシブル偏光膜の設置は吸収軸方向に斜面があるようにした）を行った。
剛軟度（ｍｍ）は、透過軸方向長辺および吸収軸方向長辺のサンプルについてそれぞれ第１面を上側の場合および第２面を上側とした場合の２パターンについてそれぞれ３回、最短直線距離Ｌ（ｍｍ）を測定（合計１２サンプル）し、それらの算術平均値とする。
また１２サンプルのいずれか１回以上の測定において、サンプルの変形やカールにより測定不可能なサンプルがあった場合には、そのサンプルは測定不可と判定する。 In the following bending resistance test in the direction in which the polyvinyl alcohol resin is perpendicular to the alignment direction and the alignment direction oriented, either from 1 to 7, wherein the bending resistance (mm) is 60mm or less The flexible polarizing film according to any one of.
<Rigidity test>
No. made by Yasuda Seiki Seisakusho A 476 cantilever type flexibility tester is used. Further, in this test, in order to eliminate the influence of static electricity, the flexible polarizing film used in the test was appropriately statically eliminated.
A rectangular object (flexible polarizing film) of 50 mm (absorption axis direction) x 150 mm (transmission axis direction), with a flat top (50 mm x 150 mm: the same size as the flexible polarizing film), and a 45 ° slope at one end of the long side. It is installed so that it fits on the top surface of the SUS plate base 41, which has a smooth trapezoidal cross section. The flexible polarizing film was installed so that there was a slope in the transmission axis direction.
The flexible polarizing film is gently slid and moved to the slope side at an extrusion speed of 10 mm / sec (1). The movement of the flexible polarizing film was stopped at the point where the tip of the flexible polarizing film first touched the slope (2). The distance L (mm) that the sample has moved when the top is flat is measured.
A rectangular object (flexible polarizing film) of 50 mm (transmission axis direction) × 150 mm (absorption axis direction) was subjected to the same operation as described above (however, the flexible polarizing film was installed so that there was a slope in the absorption axis direction). ..
The rigidity (mm) is the shortest linear distance three times for each of the two patterns when the first surface is on the upper side and the second surface is on the upper side for the samples on the long side in the transmission axis direction and the long side in the absorption axis direction. L (mm) is measured (12 samples in total) and used as their arithmetic mean value.
If there is a sample that cannot be measured due to deformation or curl of the sample in any one or more measurements of the 12 samples, it is determined that the sample cannot be measured.
Ｐ＞−（１００．９２９Ｔ−４２．４−１）×１００（ただし、Ｔ＜４２．３）、又は、
