Patent ID: 7729027

Claim:
A method for producing an image-formed object comprising a background region where optical diffraction structure for background is formed and at least one inset region provided so as to be inset in the background region, the optical diffraction structure for background focusing a hologram image of a predetermined design at a predetermined image-formation distance, and the optical diffraction structure for inset focusing a hologram image of the same design and color as the hologram image of the optical diffraction structure for background, the hologram image of the inset region being focused at an image-formation distance different from the image-formation distance of the optical diffraction structure for background, wherein a transfer step is included for each of a plurality of optical diffraction structures, the transfer step has the following steps: superimposing a transfer original plate where transfer pattern of the optical diffraction structure is formed, onto an object to be transferred where a thermoplastic resin layer is laminated on a base member, irradiating a light energy line toward the superimposed portion, transferring the transfer pattern onto the object to be transferred by fusing the resin layer with heat based on the light energy line, and moving irradiation position of the light energy line L such that a region corresponding to the optical diffraction structure is formed on the object to be transferred with the transfer pattern to be transferred.
