Abstract:
(EN) An objective of the present invention is to provide an optical film with zero retardation, which is free from the occurrence of cracks or cutting dust, while being suppressed in variation of the retardation value. Another objective of the present invention is to provide a polarizing plate which is provided with this optical film. This optical film contains a cycloolefin resin and a compound having a negative intrinsic birefringence and a weight average molecular weight within the range of 500-14,000, and is characterized in that: the cycloolefin resin is contained in an amount within the range of 51-99% by mass; the compound having a negative intrinsic birefringence i s contained in an amount within the range of 1-49% by mass; the optical film has a film thickness within the range of 5-20 ìm; the in-plane retardation value Ro (nm) of the film is within the range of 0 ≤ Ro ≤ 5; and the retardation value Rt (nm) in the film thickness direction is within the range of -10 ≤ Rt ≤ 10.
(FR) L'objet de la présente invention consiste à pourvoir à un film optique à retard nul, sans apparition de fissures ou de poussière de coupe, tout en étant dépourvu d'une variation de la valeur de retard. Un autre objet de la présente invention est de fournir une plaque de polarisation qui comprend ce film optique. Ce film optique contient une résine cyclo-oléfinique et un composé ayant une biréfringence intrinsèque négative et une masse moléculaire moyenne en poids se situant dans la plage de 500 à 14 000, et est caractérisé en ce que : la résine cyclo-oléfinique est contenue en une quantité inscrite dans la plage de 51 à 99 % en masse; le composé présentant une biréfringence intrinsèque négative est contenu en une quantité inscrite dans la plage de 1 à 49 % en masse; le film optique a une épaisseur de film dans la plage de 5 à 20 µm; la valeur de retard dans le plan Ro (nm) du film est inscrite dans la plage de 0 ≤ Ro ≤ 5; et la valeur de retard Rt (nm) dans la direction de l'épaisseur du film est inscrite dans la plage -10 ≤ Rt ≤ 10.
(JA) 本発明の課題は、クラックや切り粉の発生が生じず、また、位相差値の変動が少ないゼロ位相差性の光学フィルムを提供することである。さらに、当該光学フィルムを具備した偏光板及び提供することである。 当該光学フィルムは、シクロオレフィン系樹脂と、重量平均分子量が500~14000の範囲内の固有複屈折率が負である化合物を含有する光学フィルムであって、前記シクロオレフィン系樹脂が51~99質量%の範囲内で含有され、かつ前記固有複屈折率が負である化合物が1~49質量%の範囲内で含有されており、前記光学フィルムの膜の厚さが5~20μmの範囲内であり、フィルム面内の位相差値Ro(nm)が0≦Ro≦5の範囲であり、フィルム膜厚方向の位相差値Rt(nm)が-10≦Rt≦10の範囲であることを特徴とする。
