摘要:
An object of the present invention is to provide an authenticity indicator that cannot be easily forged, that is clearly distinguishable, and that can be elaborately designed. An authenticity indicator 101 is in the form of a sheet and can be checked for its authenticity by observing the light reflected from it. The authenticity indicator comprises a first reflective layer 12 comprising a reflective area 12a that reflects specified light, and a second reflective layer 15 that reflects specified light. The reflective area of the first reflective layer has a cholesteric liquid crystalline structure. The second reflective layer comprises a volume hologram.

The invention provides a process capable of fabricating a cholesteric liquid crystal medium having a volume hologram with efficiency yet without recourse to complicated steps such as an alignment step. This is achievable as follows. A volume hologram layer is formed on a substrate, and a cholesteric liquid crystal layer is then formed on another substrate comprising a center substrate film that is subjected to bondable treatment. The volume hologram layer is applied to the center substrate film that is subjected to bondable treatment, and placed in a state where the volume hologram layer and cholesteric liquid crystal layer are laminated together via the substrate. The substrate is peeled off the volume hologram layer, and an adhesive layer is formed on the surface of the volume hologram layer off which the substrate is peeled off, followed by the provision of the substrate on the adhesive layer. Finally, the multilayer structure is shaped into a label form of cholesteric liquid crystal medium having a volume hologram layer.

A volume hologram layer (2) is formed on a substrate (1), and a cholesteric liquid crystal layer (3) is then formed on the hologram layer (2). After the substrate (1) is peeled off the volume hologram layer (2), an adhesive layer (4) is formed on the surface of the volume hologram layer (2) with the substrate (1) peeled off, and another substrate (5) is then formed on the adhesive layer (4). Finally, a label form of cholesteric liquid crystal medium having a volume hologram is shaped out of the resulting multilayer structure; it is thus possible to fabricate cholesteric liquid crystal media having a volume hologram with efficiency yet without recourse to any complicated steps such as an alignment step.
