Abstract: front page image
(EN)The objective of the present invention is to provide an optical film which has an optical function layer on a supporting body that is mainly composed of a cellulose derivative. An optical film according to the present invention has an optical function layer on at least one surface of a film-like supporting body, and is characterized in that: the supporting body contains a cellulose derivative that has an enhanced elongation at break; and the elongation at break of the supporting body is 110% or more of the elongation at break of a supporting body that contains a cellulose derivative, the elongation at break of which is not enhanced.
(FR)L'invention concerne un film optique qui possède une couche de fonction optique sur un corps de support principalement composé d'un dérivé de cellulose. Un film optique selon la présente invention possède une couche de fonction optique sur au moins une surface d'un corps de support sous forme de film et est caractérisé en ce que : le corps de support contient un dérivé de cellulose qui présente un allongement à la rupture renforcé ; et l'allongement à la rupture du corps de support est égal à 110 % ou plus de l'allongement à la rupture d'un corps de support contenant un dérivé de cellulose dont l'allongement à la rupture n'est pas renforcé.
(JA) 本発明の課題は、セルロース誘導体を主成分とする支持体上に光学機能層を有する光学フィルムを提供することである。 本発明の光学フィルムは、フィルム状の支持体の少なくとも一方の面上に光学機能層を有する光学フィルムであって、前記支持体は破断伸度が増強されたセルロース誘導体を含有し、当該支持体が、破断伸度が増強されていないセルロース誘導体を含有する支持体の破断伸度に対して110%以上の破断伸度を有することを特徴とする。
