Multilayered volume hologram structure, and label for making multilayered volume hologram structure

   
   

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.
