Method of producing volume hologram laminate

摘要

A main object of the present invention is to provide a method of producing a volume hologram laminate which can regenerate a hologram image in an arbitrary wavelength by a simple process. To attain the object, the present invention provides a method of producing a volume hologram laminate using a volume hologram forming substrate which comprises: a substrate, a volume hologram layer formed on the substrate and containing a photopolymerizable material, a resin layer, formed on the substrate so as to contact to the volume hologram layer, containing a resin and a polymerizable compound, characterized in that the producing method comprises processes of: a hologram recording process to record a volume hologram to the volume hologram layer, a substance transit process of transiting the polymerizable compound to the volume hologram layer, and an after-treatment process of polymerizing the polymerizable compound.

1. A volume hologram laminate comprising:
a substrate, a volume hologram layer formed on the substrate and containing a photopolymerizable compound, in which a transmission volume hologram is recorded by forming an interference fringe, and a volume hologram-laminated part formed so as to contact to the volume hologram layer and comprising a resin layer which contains a photopolymerizable compound, and a transparent resin selected from the group consisting of a polymethyl methacrylate resin, a polyvinyl acetate resin, and a polyester resin, wherein an interference fringe is formed in the resin layer, and wherein a period of the interference fringe formed in the volume hologram layer is bigger than a period of the interference fringe formed in the resin layer, and a period of the interference fringe formed in the resin layer is constant in the entire resin layer.
