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.
