ABSTRACT:
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.
