<p>PROBLEM TO BE SOLVED: To provide a manufacturing method for a hologram sheet whose constitution is simple and inexpensive and which has high forgery preventing property since the entire product has intense brightness and intense iris. SOLUTION: The hologram sheet is manufactured by the following stages (1)-(5). (1) A stage for providing a radiation curing type hologram ink layer containing a plurality of hologram fine pieces on the surface of a base material. (2) A stage for irradiating the ink layer with a radiation to imperfectly cure the ink layer. (3) A stage for pressing a pressing base material having smoothness and radiation transparency on the imperfectly cured ink layer. (4) A stage for irradiating the ink layer with a radiation from the pressing base material side to perfectly cure the ink layer. (5) A stage for peeling the pressing base material from the perfectly cured ink layer.</p> |
