Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an acrylic resin film not damaged in its feature, excellent in bending whitening resistance, improved in its surface properties by reducing the projected parts on the surface of the film such as a fish-eye or the like, not generating printing omission, enhanced in its film thickness accuracy and improved in color irregularity in compounding of a colorant. SOLUTION: In molding a film from an acrylic resin having a multilayered structure including a rubber elastomer layer by a melt extrusion method, both surfaces of the film are brought into contact with rolls or metal belts to be molded during a period when the mean film thickness of lip clearance/film is 10-1.2, an air gap is not more than 100 mm and the acrylic resin having the multilayered structure including the rubber elastomer layer is not less than Tg.
