摘要： A hologram recording medium includes a support substrate, a hologram recording material layer, a transparent gel layer, and a protective substrate. The transparent gel layer is formed of a resin material gelated by cross-linking, or more specifically, such as gelated silicone cross-linked by hydrosilylation or gelated polyurethane cross-linked by polyaddition of isocyanic ester to alcohol. The transparent gel layer serves as a filler to compensate for variations in thickness of the hologram recording material layer. The transparent gel layer fills those gaps occurring between the recording material layer of the hologram recording medium and the adjacent substrate, without having adverse effects on the recording characteristics, in a manner that allows for controlling the refractive index.
