Abstract: Disclosed is a hologram transfer film which can realize easy and good transfer of a hologram and, at the same time, can realize stable transfer of the hologram in a transfer process. The hologram transfer film comprises: a substrate film; and a transfer layer provided on the substrate film, the transfer layer comprising a hologram-forming layer and a heat-sensitive adhesive layer provided in that order on the substrate film, the hologram-forming layer having a breaking strain of 0.5 to 15% at 25° C. and a breaking strain of 0.5 to 30% at 120° C.

Abstract: A phase-change optical information recording medium capable of recording information therein, reproducing recorded information therefrom, rewriting recorded information, and erasing recorded information therefrom, which phase-change optical information recording medium is provided with a recording layer containing therein a phase-change recording material including Ge, Ga, Sb, Te, and one element selected from the group consisting of Mg and Ca, which recording material is capable of performing a reversible phase transition from a noncrystalline phase to a crystalline phase and vice verse with the application of an electromagnetic wave thereto.

Abstract: This invention relates to a process for forming a reflection hologram. A process for forming a volume reflection hologram is provided wherein the formation of secondary holograms is suppressed by the placement of index matched filters contiguous to at least one surface of the photosensitive recording element during formation of the hologram.
