Hologram recording composition, hologram recording medium, hologram optical element, optical device and optical component using same, and method for forming hologram diffraction grating

Abstract

To provide a hologram recording composition capable of further improving diffraction characteristics and the transparency of a hologram. The present technology provides a hologram recording composition containing at least a chromic dye whose decolorized body has a structure containing a primary and/or secondary amino group, an epoxy monomer, and a polymerization initiator. The present technology also provides a hologram recording medium including a photosensitive layer containing at least a chromic dye whose decolorized body has a structure containing a primary and/or secondary amino group, an epoxy monomer, and a polymerization initiator. Furthermore, the present technology also provides a hologram optical element using the hologram recording medium. Moreover, the present technology also provides an optical device and an optical component using the hologram optical element. The present technology also provides a method for forming a hologram diffraction grating, the method including causing the hologram recording medium to react selectively by an electromagnetic beam having a spatially modulated amplitude.
