Abstract
To provide a hologram recording composition that can further improve diffraction characteristics and transparency of a hologram. The present technology provides a hologram recording composition containing a heteropoly acid, a photopolymerizable monomer, a photopolymerization initiator, and a sensitizing dye having absorption in a visible light region in the presence of an acid. The present technology also provides a hologram recording medium including at least a photocurable resin layer containing a heteropoly acid, a photopolymerizable monomer, a photopolymerization initiator, and a sensitizing dye having absorption in a visible light region in the presence of an acid. Furthermore, the present technology also provides a diffraction optical element using the hologram recording medium. Moreover, the present technology also provides an optical device, an optical component, and an image display device using the diffraction optical element.
