On the genuine characteristic identification body, and genuine characteristic identification structural

摘要

PPROBLEM TO BE SOLVED: To avoid conventional problems that an authenticity identifying structure having a hologram or the like made of a cholesteric liquid crystal layer shows insufficient heat resistance when the structure is to be applied on the object requiring identification for the authenticity or that the structure after applied on the object for authenticity identification has insufficient heat resistance. PSOLUTION: The structure comprises layers of an adhesive layer 3, a heat resistance improving layer 4, a cholesteric liquid crystal layer 5 having a fine rugged pattern 5a such as a hologram on its lower face, and a protective layer 6 formed on the object 2 for authenticity identification. These layers are formed as a structure of a transfer sheet so that the layers can be applied on the object 2 for authenticity identification by using a transfer method. PCOPYRIGHT: (C)2003,JPO
