Abstract: There are provided a hologram laminate and a hologram label which do not involve any problem in the production process per se of forging preventive labels using a volume hologram, can provide a reliable process of the attainment of forgery preventive effect, and can make difficult to notice the signs of the forgery preventive processing. In applying a protective film 108 onto a hologram 107 through a second pressure-sensitive adhesive 109, the adhesive strength is partially varied. By virtue of this construction, upon separation of the protective film 108, the second pressure-sensitive adhesive 109 is partially left on the hologram 107, so that the fact of the separation can be found out.

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.

Likewise, the adhesive strength of a first pressure-sensitive adhesive 106 can be partially changed. Further, the adhesive strength of the first pressure-sensitive adhesive 106 is larger than 1% tensile strength of the hologram 107.
