GENUINENESS IDENTIFYING BODY, INFORMATION RECORDING MEDIUM HAVING THE SAME AND ARTICLE

摘要

PROBLEM TO BE SOLVED: To avert the possibility that hologram seals, etc., are forged by a person which has illicit intention and learns a manufacturing technique by additional complexity or the difficulty in manufacture to the hologram seals, etc., and to eliminate the probability that the display contents thereof are legible depending upon angles. SOLUTION: The genuineness identifying body S which is formed by laminating a light diffraction structure layer 4 on the under surface of a latent image sheet 5 consisting of <=2 regions varying in phase differences and having latent image patterns visible through a polarizing plate and further laminating a light reflective layer 6 on the under surface is preferably applied to an adherend 2 through an adhesive layer 3.
