To obtain an acrylic resin film hardly causing whitening when folded, excellent in impact resistance, transparency and designing properties, and useful for surface-layered member by regulating the film so as to be composed of a composition comprising an acrylic resin and an acrylic elastic particles, and so as to have a value not less than a specific value of a prescribed heat shrinkage.
This acrylic resin film comprises (A) an acrylic resin such as a mixture of one or more kinds of acrylic polymers having 70,000-200,000 weight average molecular weights, with one or more kinds of acrylic polymers having >200,000 weight average molecular weights, or the like, preferably in an amount of ≥50 pts.wt. (based on 100 pts.wt. total of the components A and B), and (B) acrylic elastomer particles of acrylic polymers with multilayered structures including rubbery elastic layers, or the like, (preferably having 50-500 nm particle diameters), preferably in an amount of ≤50 pts.wt., and has ≥5%, preferably ≥20% heat shrinkage in the direction showing the maximum heat shrinkage in a heat shrinkage test, and ≤5% heat shrinkage in the direction crossing to the direction. The thickness of the film is preferably 0.01-0.6 mm.
