PURPOSE:To realize a molded form having high surface hardness and characteristics higher than coatability by injection-molding a molding resin in a mold and irradiating a coated substance coated with a photo-setting sheet with light. CONSTITUTION:In a photo-setting sheet, a photo-setting resin layer formed of a photo-setting resin composition mainly comprising an acrylic resin having weight average molecular weight of 50000-1000000 and Tg of 0-100 deg.C and formed in a solid shape at normal temperature, a crosslinking agent capable of reacting with the resin, a compound having a reactive vinyl group and a photopolymerization initiator is laminated on a sheet base material. The photo-setting sheet 1 is laid in the recess 41 of a movable mold 4 in such a way that a photo-setting resin layer 1a is positioned on the movable mold 4 side, and a hot plate 2 is moved and the sheet 1 is softened and cut. Air is jetted against the sheet 1 side and air is sucked from a suction port 42 to hold the sheet 1 onto the inner surface of the movable mold 4, the hot plate 2 is shifted and the movable mold 4 and a stationary mold 5 are mold-clamped, and a molding resin is injected into a cavity from an injection molding machine 7, thus acquiring a coated substance, on a surface of which the sheet 1 is formed. |
