发明名称 Volume hologram laminate
摘要 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 laminate 1 of the invention has a first adhesive layer 3, a volume hologram layer 5, a second adhesive layer 4 and a surface protective film 6 formed in that order on a substrate 1, 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 5x10<5 >Pa-5x10<7 >Pa 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 5x10<4 >Pa or at least 2.5x10<5 >Pa at 50° C. when measured at 6.28 rad/s.
