1. A decorative film for insert molding to be formed in a three-dimensional shape before insert molding, the decorative film comprising:
a multilayer film having a first main surface and a second main surface and including a first acrylic resin layer comprising an acrylic-based resin, a second acrylic resin layer comprising an acrylic-based resin, and a first polycarbonate resin layer between the first acrylic resin layer and the second acrylic resin layer, the first polycarbonate resin layer comprising a polycarbonate-based resin, the multilayer film being transmissive to visible light;
a gravure print layer on the first main surface of the multilayer film, the gravure print layer including a graphic layer including a gravure-printed graphic element, the gravure print layer being transmissive to visible light;
a first backer film located opposite to the multilayer film across the gravure print layer, the first backer film comprising an acrylonitrile butadiene styrene-based resin transmissive to visible light, the first backer film being transmissive to visible light;
a second backer film located opposite to the multilayer film across the first backer film, the second backer film including a third acrylic resin layer comprising an acrylic-based resin, a fourth acrylic resin layer comprising an acrylic-based resin, and a second polycarbonate resin layer between the third acrylic resin layer and the fourth acrylic resin layer, the second polycarbonate resin layer comprising a polycarbonate-based resin, the second backer film being transmissive to visible light; and
a light-transmissive patterned layer including a light-transmissive pattern being transmissive to visible light, the light-transmissive pattern in the light-transmissive patterned layer being located to allow visible light to pass through a predetermined portion of the graphic element in the graphic layer.
