Abstract: The present invention pertains to: an acrylic laminate film containing an acrylic copolymer and having a three-layer structure of an inner layer, an intermediate layer, and an outer layer; a method for producing same; and a deco sheet produced therefrom. An object of the present invention is to provide a three-layer-structured acrylic laminate film produced from an acrylic copolymer. Another object of the present invention is to provide: an acrylic laminate film having significantly improved optical properties and surface smoothness by using an acrylic copolymer alone without mixing the same with additional polymers; and a method for producing the acrylic laminate film. Still another object of the present invention is to provide: an acrylic laminate film that exhibits significantly reduced whitening even when a flexural stress is applied; and a method for producing the acrylic laminate film.
