<p>PURPOSE:To enable various kinds of individual information to be recorded continuously and thus prevent any counterfeit or revision by producing patterns with different reproducing wave lengths as a hologram in a valuable securities having a hologram stuck on a part or entire part of the main body of the valuable securities. CONSTITUTION:When adapted to a lottery ticket, a desired pattern 22 is printed on a part of the surface of a base material, and a Lippman hologram 23 is stuck on the other part of surface of the base material 21. The Lippman hologram 23 is composed of successively laminating a first adhesive layer 231, a hologram layer 232 having an optically polymerized photopolymer and dispersing agent integrated, a second adhesive layer 233 and protective sheet 234 on the surface of the base material 21. In manufacturing the hologram 232, by irradiating ultraviolet rays having some light exposure prior to the close- adhering of a film with a dispersing agent applied to an optically polymerized photopolymer, a constant amount of monomer is polymerized, and by controlling an amount of monomer regarding the shift of reproducing wave lengths, a desired shift of the reproducing wave lengths are obtained.</p> |
