摘要： A decorative film for insert molding includes a gravure-printed graphic layer and a light-transmissive patterned layer and has high dimensional accuracy and delicate and rich tone expression. A multilayer film includes first and second layers containing an acrylic-based resin, and a polycarbonate resin layer located between the first and second layers and containing a polycarbonate-based resin. The multilayer film is transmissive to visible light. A first gravure print layer is located on a first main surface of the multilayer film, includes a first graphic layer, and is transmissive. A backer film contains a polycarbonate-based resin and is transmissive. The first graphic layer includes a first image at a predetermined position in a three-dimensional shape of a decorative film formed in the three-dimensional shape. A patterned layer includes a pattern patterned to allow visible light to pass through the first image at the predetermined position in the three-dimensional shape.

摘要： A decorative film for insert molding includes a gravure-printed graphic layer and a light-transmissive patterned layer with high dimensional accuracy and has a reduced flow of gravure ink in manufacturing of a polycarbonate resin molded product. A multilayer film transmissive to visible light includes two acrylic resin layers and a first polycarbonate resin layer containing a polycarbonate-based resin and located between the acrylic resin layers. The gravure print layer includes a graphic layer with a gravure-printed graphic element. A first backer film contains an acrylonitrile butadiene styrene-based (ABS-based) resin transmissive to visible light. A second backer film includes two additional resin layers and a second polycarbonate resin layer located between the two additional acrylic resin layers. A light-transmissive patterned layer is located to allow visible light to pass through a predetermined portion in the graphic layer.
