Title (EN) OPTICAL FILM AND METHOD FOR MANUFACTURING SAME
(FR) FILM OPTIQUE ET PROCÉDÉ POUR SA FABRICATION
(JA) 光学フィルム及びその製造方法
Abstract:
(EN) Provided is an optical film obtained by roughening at least one surface of a film containing an alicyclic structure-containing polymer. At the at least one surface, a maximum height Rz is 150-3000 nm inclusive, and an arithmetic mean roughness Ra is 30-1000 nm inclusive. The optical film preferably has an internal haze of 5% or less. The alicyclic structure-containing polymer is preferably a specific block copolymer hydride [E]. A method for manufacturing the optical film is collectively disclosed, the method including a roughening step.
(FR) L'invention concerne un voile optique obtenu par rugosification d'au moins une surface d'un film contenant un polymère contenant une structure alicyclique. Au niveau de ladite surface, une hauteur maximale Rz est de 150 à 3 000 nm inclus, et une moyenne arithmétique de la rugosité Ra est de 30 à 1 000 nm inclus. Le film optique présente de préférence un voile interne de 5 % ou moins. Le polymère contenant une structure alicyclique est de préférence un hybride de copolymère séquencé spécifique [E]. L'invention concerne également un procédé de fabrication du film optique, le procédé comprenant une étape de rugosification.
(JA) 脂環式構造含有重合体を含むフィルムの、少なくとも一方の面を粗化してなる光学フィルムであって、少なくとも一方の面において、最大高さRzが150nm以上3000nm以下であり、かつ、算術平均粗さRaが30nm以上1000nm以下である、光学フィルム。前記光学フィルムは、好ましくは、その内部ヘイズが5%以下である。前記脂環式構造含有重合体は、好ましくは、特定のブロック共重合体水素化物[E]である。粗化の工程を含む、光学フィルムの製造方法も併せて開示される。
