<p>PROBLEM TO BE SOLVED: To provide such a hologram sheet suitable for preventing a package from being opened/closed, repackaged, etc., as is transparent before being peeled off, a pattern appears after being peeled off, re-bonding is difficult, it easily is found even if it is forcibly bonded again by using a relief hologram. SOLUTION: This hologram sheet comprises a layer 2 having relief surface 4 forming a relief hologram and a layer 6 burying the relief surface 4, and initially, both layers are mutually bonded, and an image recorded in the hologram becomes reproducible by mutually peeling off both layers from each other. Both layers are bonded with one of or combination of adhesives like an adhesive allowing re-peeling off after bonding, an adhesive losing adhesive strength with a normal pressure once peeled off, a pressure-sensing adhesive, and a melt- extrusion of a resin not bonded to a material on relief surface.</p> |
