Abstract:
A hologram laminate comprising: a substrate; a hologram layer provided on the substrate through a first pressure-sensitive adhesive layer; and a transparent film provided on the hologram layer through a second pressure-sensitive adhesive layer,the adhesive strength between the substrate and the hologram layer being larger than the adhesive strength between the hologram layer and the transparent film, the second pressure-sensitive adhesive layer having a first portion and a second portion, the first portion having an adhesive property such that the adhesive strength between the first portion and the transparent film is larger than the adhesive strength between the first portion and the hologram layer and, hence, when the transparent film is peeled off, the first portion is left on the transparent film side, the second portion having an adhesive property such that the adhesive strength between the second portion and the transparent film is smaller than the adhesive strength between the second portion and the hologram layer and, hence, when the transparent film is peeled off, the second portion is left on the hologram layer.
