AUTHENTICITY IDENTIFIER, AUTHENTICITY IDENTIFICATION TOOL, COMBINATION OF THE IDENTIFICATION AND TOOL, AND METHOD FOR AUTHENTICITY IDENTIFICATION

摘要

PROBLEM TO BE SOLVED: To solve the problem that conventionally it has little inhibitions in being repaired by removing or clipping off a hologram even though the hologram made from a cholecteric liquid crystal layer is high counterfeit-resistant.

SOLUTION: An authenticity identifier with a high counterfeit-resistance based on each characteristic of a hidden pattern layer 3 and an optical transparent hologram layer 4 by laminating the pattern layer 3 composed of a background 3a, a hidden pattern 3b, etc., on an information recording medium and a variety of goods and by laminating preferably the hologram layer 4 using the cholecteric liquid crystal layer on a portion of the pattern layer 3, so that it becomes possible for the authenticity identifier to easily detect even though only the hologram layer 4 has been repaired.
