Abstract: The present invention provides a lengthy volume hologram layer transfer foil capable of transferring a volume hologram layer continuously to a specified position of a transfer-receiving member. The above problem can be solved by a lengthy volume hologram layer transfer foil according to the present invention, the transfer foil is formed lengthwise and comprises: a substrate, a volume hologram layer which is formed on the substrate and in which a volume hologram is recorded, and a heat seal layer which is formed on the volume hologram layer and which contains a thermoplastic resin, the transfer foil being characterized in that it is provided with a cut portion formed so as to penetrate through the heat seal layer and to cut at least a part of the volume hologram layer, on at least a part of the full width in a direction perpendicular to the longitudinal direction thereof.

Abstract: In the multilayer volume hologram 1 of the invention, the adhesive layer 5, volume hologram 6 and surface protective film 7 are laminated on the application member 2 in this order, and the breaking strength of the hologram layer should be larger than the peel strength between the surface protective film and the volume hologram layer and smaller than the peel strength with which the hologram layer is peeled off the application member and the breaking strength of the surface protective film. This multilayer volume hologram provides a more improved protection for the volume hologram. A portrait replacement or falsification of an information area ensures that the volume hologram layer can break down. Thus, more reliable counterfeit-proofness is achievable.
