Title
(EN) (METH)ACRYLIC RESIN COMPOSITION AND (METH)ACRYLIC RESIN FILM USING THE SAME
(JA) (メタ)アクリル系樹脂組成物及びそれを用いた(メタ)アクリル系樹脂フィルム
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a (meth)acrylic resin composition capable of forming a film which exhibits good toughness and has a small heat shrinkage rate, a (meth)acrylic resin film using the (meth)acrylic resin composition, and a polarizing plate.

SOLUTION: There are provided: the (meth)acrylic resin composition which contains a (meth)acrylic resin A and a (meth)acrylic resin B having a glass transition temperature lower than that of the (meth)acrylic resin A and a weight-average molecular weight of 100,000 or more; the (meth)acrylic resin film using the (meth)acrylic resin composition; a stretched film thereof; and the polarizing plate including the (meth)acrylic resin film or the stretched film thereof.
