Description

《収縮率》
上記偏光板小片を８０℃−ｄｒｙと６０℃−９０ＲＨ％の恒温恒湿機中に放置し、６０時間後の延伸方向の縮み量を測定し、元の長さ（１００ｍｍ）に対する縮み量の割合を収縮率とし求め、以下の３段階で評価をした。
なお、「ｄｒｙ」とは、湿度調整機能付のオーブンで、温度のみコントロールし、湿度のコントロールを行わなかった場合の試験条件である。「△」評価以上の場合、実際の使用時に特に問題ない。
（評価基準）
○：収縮率が０．２％以下
△：収縮率が０．２％より大きくて０．４％以下
×：収縮率が０．４％を超える。
"Shrinkage factor"
The polarizing plate piece is left in a constant temperature and humidity chamber of 80 ° C.-dry and 60 ° C.-90 RH%, the amount of shrinkage in the stretching direction after 60 hours is measured, and the ratio of the amount of shrinkage to the original length (100 mm) Was determined as the shrinkage rate and evaluated in the following three stages.
Note that “dry” is a test condition when only the temperature is controlled and humidity is not controlled in an oven with a humidity adjusting function. In the case of “△” evaluation or higher, there is no problem in actual use.
(Evaluation criteria)
◯: Shrinkage rate is 0.2% or less Δ: Shrinkage rate is greater than 0.2% and 0.4% or less ×: Shrinkage rate exceeds 0.4%
