Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 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 consis…
