<p><P>PROBLEM TO BE SOLVED: To visually recognize a latent image pattern with transmitted light from the rear face under a normal light source by removing at least a part of a light reflection layer which forms a hologram sheet and constituting the light reflection layer by image line design which becomes effective for forgery prevention and authenticity discrimination, and to visually recognize the latent image pattern even when the front face is irradiated with an excitation light source by providing a florescent light emission layer at an arbitrary position of a base material to which the hologram sheet is stuck. <P>SOLUTION: A hologram sheet 2 which has a hologram formation layer 4 is stuck to a base material 1, a part of a light reflection layer 6 which constitutes the hologram formation layer 4 is removed, a background area 9 is constituted as a first light transmissive area, a latent image area 10 is formed as a second light transmissive area, and a latent image pattern 'B' is formed by using continuous image lines as background image lines 11 in the background area 9, and using branched image lines 12a or segmented image lines 12b as latent image lines in the latent image area 10. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
