Abstract
The present invention relates to a volume hologram laminate with low generation of spotty hologram flaws in the volume hologram layer even when kept under pressurized conditions during storage, and to a volume hologram laminate-fabricating label. The volume hologram laminateof the invention has a first adhesive layer, a volume hologram layer, a second adhesive layerand a surface protective filmformed in that order on a substrate, wherein the volume hologram layer is a hologram recording in a recording material comprising a matrix polymer and a photopolymerizable compound, having a glass transition point of 30° C.-70° C. and a dynamic storage elastic modulus of 5×10Pa-5×10Pa at 50° C. when measured at 6.28 rad/s, and the second adhesive layer has a dynamic storage elastic modulus of no greater than 5×10Pa or at least 2.5×10Pa at 50° C. when measured at 6.28 rad/s.
