Estimating the term…
A multilayered volume hologram structure of the invention comprises a substrate 2 for a certificate or the like, and an adhesive layer 5, a volume hologram layer 5 and a surface protective film 7 laminated on the substrate in the described order. When a multilayer structure consisting of the volume hologram layer 5 and surface protective layer 5 is forcibly released from the substrate for the purpose of making a photograph replacement or falsifying a personal information area, the volume hologram image can break down certainly, thereby ensuring prevention of falsification. A multilayered volume hologram structure-making label is useful for making a multilayered volume hologram structure.
A multilayered volume hologram structure, characterized by comprising a substrate for a certificate or the like, and an adhesive layer, a volume hologram layer, a resin layer containing a monomer or a plasticizer and a surface protective film laminated on said substrate in the described order, wherein said adhesive layer is immediately adjacent a first side of the volume hologram layer, a first side of said resin layer is immediately adjacent to and in direct contact with a second side of the volume hologram layer, and a second side of said resin layer is immediately adjacent said surface protective film.
A multilayered volume hologram structure, characterized by comprising a substrate for a certificate or the like, and an adhesive layer, a volume hologram layer, a brittle layer, an adhesive layer and a surface protective film laminated on said substrate in the described order.
