Abstract: Embodiments of the invention relate to a poly(meth)acrylimide film and a method for manufacturing such a film. At least one embodiment provides a poly(meth)acrylimide film that has (i) a total light transmittance of over 90% and (ii) haze of 2.0% or less. This film preferably has retardation of less than 50 nm. The method for manufacturing this film includes the following steps: (A) using a device provided with an extruder and a T die, a poly(meth)acrylimide molten film is continuously extruded from the T die; and (B) the poly(meth)acrylimide molten film is loaded by being fed between a rotating or circulating first mirrored-surface body and a rotating or circulating second mirrored-surface body, and then the film is pressed. During these steps, (C) the surface temperature of the first mirrored-surface body is in the range 100-200° C., and (D) the surface temperature of the second mirrored-surface body is in the range 20-200° C.

Abstract: Provided is adhesive resin compositions comprising (A) 30 to 70% by mass of an acid-modified polypropylene-based resin; (B) 20 to 60% by mass of a polypropylene-based resin; and (C) 2 to 20% by mass of a copolymer of ethylene and one or more kinds of comonomers selected from the group consisting of vinyl acetate, alkyl methacrylate, and alkyl acrylate, with the proviso that the sum of the percentages of the above component (A), the above component (B), and the above component (C) is 100% by mass.
