Title (EN) STRETCHED FILM AND RETARDATION FILM
(FR) FILM ÉTIRÉ ET FILM DE RETARD
(JA) 延伸フィルムおよび位相差フィルム
Abstract:
(EN) This stretched film comprises a resin composition including a methacrylic resin (A) and a polycarbonate resin (B), wherein the methacrylic resin (A) contains: 10-50 mass% of a structural unit (a1) derived from a methacrylate polycyclic aliphatic hydrocarbon ester; and 50-90 mass% of a structural unit (a2) derived from a (meth)acrylate ester other than methacrylate polycyclic aliphatic hydrocarbon ester. The mass ratio (A)/(B) of the methacrylic resin (A) to the polycarbonate resin (B) is 85/15 to 50/50.
(FR) La présente invention concerne un film étiré comprenant une composition de résine comprenant une résine méthacrylique (A) et une résine polycarbonate (B), la résine méthacrylique (A) contenant : 10 à 50 % en masse d'une unité structurelle (a1) dérivé d'un ester d'hydrocarbure aliphatique polycyclique méthacrylate ; et 50 à 90 % en masse d'une unité structurelle (a2) dérivée d'un ester (méth)acrylate autre que l'ester d'hydrocarbure aliphatique polycyclique méthacrylate. Le rapport massique (A)/(B) de la résine méthacrylique (A) par rapport à la résine polycarbonate (B) est compris entre 85/15 et 50/50.
(JA) メタクリル酸多環式脂肪族炭化水素エステルに由来する構造単位(a1)10~50質量%、およびメタクリル酸多環式脂肪族炭化水素エステル以外の(メタ)アクリル酸エステルに由来する構造単位(a2)50~90質量%を含有してなるメタクリル樹脂(A)と、ポリカーボネート樹脂(B)とを、ポリカーボネート樹脂(B)に対するメタクリル樹脂(A)の質量比(A)/(B)が85/15~50/50にて、含有する樹脂組成物を含んで成る延伸フィルム。
