摘要

PPROBLEM TO BE SOLVED: To provide a medium for judging authenticity capable of eliminating problems that it is difficult to shorten manufacturing time and that it is difficult to change the pattern of a decision part for judging authenticity because many stages are required at the time of manufacturing an embossing mold in the case of forming the decision part by embossed hologram. PSOLUTION: Authenticity judgement using a polarizing plate is realized by structure where oriented film 3 and a pattern layer 4 whose incident light rotating direction is rotated are laminated on a base material 2, and a hologram forming layer 5 and a reflective layer 6 are laminated on the lower side of the base material 2 or by laminating the oriented film 3, the pattern layer 4, the hologram forming layer 5 and the reflective layer 6 on the base material 2 in this order. It is good to use a mere light reflection layer 7 instead of the hologram forming layer 5 and the reflective layer 6. PCOPYRIGHT: (C)2005,JPO&NCIPI
