<p><P>PROBLEM TO BE SOLVED: To provide a novel authenticity identifying body which unnecessitates the more complexity of appearance and the more easiness of judgement of authenticity with respect to a hologram used for confirmation of authenticity and the like. <P>SOLUTION: The authenticity identifying body 1 is composed of a cholesteric liquid crystal layer 3 formed on the upper surface or the lower surface of a transparent substrate 2, a hologram formation layer 4 formed on the lower surface of them and a reflective metal layer 5 along fine ruggedness of the hologram formation layer 4, wherein the reflective metal layer 5 is formed so as to present a pattern shape when seeing from the upper surface. In this way, the authenticity identifying body is formed. It is preferable that the cholesteric liquid crystal layer is bilayered and it is further preferable that an adhesive layer 7 is laminated on the lower surface. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
