TRUTH OR FALSEHOOD JUDGING OBJECT, ADHESIVE SHEET FOR TRUTH OR FALSEHOOD JUDGING MEDIUM AND SHEET FOR TRANSFERRING TRUTH OR FALSEHOOD JUDGING MEDIUM

摘要

PPROBLEM TO BE SOLVED: To realize giving of resistivity to further falsification when a conventional prism sheet having a pattern formed to embed an unevenness of an uneven surface of the prism sheet is used. PSOLUTION: This truth or falsehood judging medium 1 is constituted by laminating a prism 14, a retro-reflection pattern sheet 11 having a transparent pattern layer 15 for embedding the prism 14, sequentially formed on a transparent sheet 12, and a hiding pattern layer through an adhesive layer 27A and a transparent sheet 28 on a base material 32 obtained by laminating a hiding pattern layer by an adhesive layer 27B as required. Thus, the retro-reflection pattern and the hiding pattern which is image visualized by an image visualizing means can be observed. PCOPYRIGHT: (C)2005,JPO&NCIPI
