IMAGE DISPLAY, HEAT TRANSFER SHEET USED FOR IMAGE DISPLAY AND INFORMATION DISPLAY METHOD

摘要

PURPOSE: To discriminate respective image displays and prevent the alteration and falsification of a hologram and the image by forming a photoabsorption layer in a visible area or an infrared ray area by heating in a plurality of hologram information areas in which hologram forming layers are formed by relief patterns same as or different from the interference fringe direction of the hologram forming layer. CONSTITUTION: A hologram layer 6 is constituted of a plurality of hologram information areas composed of relief patterns same as or different from the interference fringe direction of the hologram forming layer. As photoabsorption is generated in a visible area or an infrared ray area by heating in the hologram forming layer 6, emitted beam is absorbed and a part of hologram image of a hologram information recording section 10 corresponding to a heating section 15 is not regenerated to constitute a different information pattern. Thus an optional information pattern can be set by varying the heating section of the hologram information recording section 10 of the hologram forming layer 6.
