摘要:
The invention provides a hologram transfer foil (1) comprising, that includes, in order from top to bottom, a substrate (7), a volume hologram layer (2) releasably stacked on substrate (7) and comprising a volume hologram in a cured resin layer, a first heat seal layer (3) and a second heat seal layer (4). In use, the hologram transfer foil (1) is applied on the second heat seal layer (4) side over an application member. The adhesion force of volume hologram layer (2) to the application member is larger than a material fracture force for the volume hologram layer or the application member, so that the hologram transfer layer can be applied by thermo-compression to the application member. This hologram transfer foil is useful for illegal copying of the hologram layer because when the volume hologram is forcibly peeled from the application, a material fracture of the volume hologram layer or application member occurs. When a colored layer functioning as a back layer is provided, it is possible to obtain a hologram transfer foil which eliminates any adverse influence of a coloring component on the volume hologram layer.

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.
摘要:
A hologram laminate and a hologram label allow traces of separation of the hologram to be clearly left on both the adherend and the hologram label and hence makes it possible to prevent reuse of the hologram and is excellent in graphical design function and suitable for certification purposes. The hologram laminate has a colored layer, a release pattern, a transparent film, a hologram layer and a surface protective layer laminated on an adherend in the order mentioned. The hologram layer includes a volume hologram layer and a relief hologram layer having a transparent thin-film layer over the surface of a relief interference fringe pattern. When the hologram is separated between the adherend and the transparent film, the colored layer is left on the adherend in a pattern corresponding to the release pattern.
