Abstract
(EN)
Provided is an optical film having low haze and low yellow discoloration even after long-term storage in a folded state under a high-temperature, high-humidity environment. This optical film has yield point strain of 1.5% or greater. Additionally, the haze Hza of the optical film, after the film is subjected to mandrel testing in which the film is bent once at a bend radius of 1 mm and is brought back to a flat state under room temperature, is 1.5% or less.
(FR)
L'invention concerne un film optique ayant un faible trouble et une faible décoloration jaune, même après un stockage à long terme dans un état plié dans un environnement à haute température et humidité élevée. Ce film optique a une contrainte de point d'élasticité de 1,5 % ou plus. De plus, la turbidité Hz a du film optique, une fois que le film est soumis à un test de mandrin dans lequel le film est plié une fois à un rayon de courbure de 1 mm et est ramené à un état plat à température ambiante, est de 1,5 % ou moins.
(JA)
折り曲げた状態で高温高湿環境下に長時間保管された後でも、ヘーズ及び黄色度が低い光学フィルムを提供する。 本発明の光学フィルムは、降伏点歪が1.5%以上であり、かつ室温下、屈曲半径1mmで1回折り曲げて平面状に戻すマンドレル試験後のHzで表されるヘーズが1.5%以下である。
