Title (EN) OPTICAL FILM AND METHOD FOR PRODUCING SAME
(FR) FILM OPTIQUE ET SON PROCÉDÉ DE FABRICATION
(JA) 光学フィルム及び製造方法
Abstract:
(EN) An optical film which comprises a core layer, a first skin layer that is provided on one surface of the core layer, and a second skin layer that is provided on the other surface of the core layer, and wherein: the core layer is formed from a resin composition (A); the first skin layer and the second skin layer are formed from a resin composition (B) that is different from the resin composition (A); the resin composition (A) contains from 80% by weight to 100% by weight (inclusive) of an alicyclic structure-containing polymer in the total weight of the resin composition (A); the resin composition (B) contains from 95% by weight to 100% by weight (inclusive) of an alicyclic structure-containing polymer in the total weight of the resin composition (B); and the viscosity ratio ηB(ave)/ηA(ave) is from 0.3 to 3.0 (inclusive).
(FR) L'invention concerne un film optique comprenant une couche centrale, une première couche de peau qui est disposée sur une surface de la couche centrale, et une seconde couche de peau qui est disposée sur l'autre surface de la couche centrale, la couche centrale étant formée à partir d'une composition de résine (A) ; la première couche de peau et la seconde couche de peau étant formées à partir d'une composition de résine (B) qui est différente de la composition de résine (A) ; la composition de résine (A) contenant de 80 % en poids à 100 % en poids (inclus) d'un polymère contenant une structure alicyclique dans le poids total de la composition de résine (A) ; la composition de résine (B) contenant de 95 % en poids à 100 % en poids (inclus) d'un polymère contenant une structure alicyclique dans le poids total de la composition de résine (B) ; et le rapport de viscosité ηB(moyen)/ηA(moyen) étant de 0,3 à 3,0 (inclus).
(JA) コア層と、前記コア層の一方の面に設けられた第1スキン層と、前記コア層の他方の面に設けられた第2スキン層とを含み、前記コア層は、樹脂組成物(A)からなり、前記第1スキン層及び前記第2スキン層は、前記樹脂組成物(A)とは異なる樹脂組成物(B)からなり、前記樹脂組成物(A)は、前記樹脂組成物(A)の全量中80重量%以上100重量%以下の脂環式構造含有重合体を含み、前記樹脂組成物(B)は、前記樹脂組成物(B)の全量中95重量%以上100重量%以下の脂環式構造含有重合体を含み、粘度比率η(ave)/η(ave)が0.3以上3.0以下である、光学フィルム。
