Abstract:
To provide a film having high tensile strength and elongation characteristics. A methacrylic film formed of (A) a carboxyl group-containing (meth)acrylic polymer having a glass transition temperature (Tg) of 0° C. or higher and a weight-average molecular weight of 10,000 or more obtained by copolymerizing a composition containing a monoethylenically unsaturated monomer as a main component and an unsaturated monomer having a carboxyl group, and (B) an amino group-containing (meth)acrylic polymer having a glass transition temperature (Tg) of 0° C. or lower and a weight-average molecular weight of 10,000 or more obtained by copolymerizing a composition containing a monoethylenically unsaturated monomer as a main component and an unsaturated monomer having an amino group, wherein a mixing ratio of the component (A) to the component (B) is from 10:90 to 90:10 in terms of a weight ratio.
