Therefore, the purpose of the present invention is to have a protruding pattern with very excellent physical properties, to make letters, symbols, etc. difficult to erase (and to be able to supply it at low cost). To provide products and their manufacturing methods,
In order to achieve this object, the present invention molds a protruding pattern on the surface using an ultraviolet curable resin, adheres a transparent synthetic resin film or sheet to the back side of the protruding pattern, and within the frame of the protruding pattern, the A printed layer is provided on the back surface of the film or sheet, and the printed layer is made visible through the film or sheet, and a paste-like ultraviolet curing resin is applied to the intaglio pattern on the outer peripheral surface of the rotary body that is free to rotate. A transparent synthetic resin film or sheet is pressed onto the outer peripheral surface of the rotating body before the resin hardens, and ultraviolet rays are irradiated from the film or sheet side to form the protruding pattern in the intaglio pattern. The gist is that the film or sheet is integrated with the film or sheet, peeled off from the rotating body, and printed on the back side of the film or sheet within the frame of the protruding pattern.
