Document Type and Number:

WIPO Patent Application WO/2020/158300

Kind Code:

A1

Abstract:

To provide a hologram recording composition which ensures further improvement in diffraction characteristics and hologram transparency.　The present technique provides a hologram recording composition which at least comprises a chromic dye wherein a decoloring agent has a primary and/or secondary amino group-containing structure, an epoxy monomer and a polymerization initiator. The present technique further provides a hologram recording medium provided with a photosensitive layer which at least comprises a chromic dye wherein a decoloring agent has a primary and/or secondary amino group-containing structure, an epoxy monomer and a polymerization initiator. The present technique furthermore provides a hologram optical element in which the hologram recording medium is used. The present technique furthermore provides an optical device and an optical component in which the hologram optical element is used. The present technique also provides a method for forming a hologram diffraction grating, said method comprising selectively reacting the a hologram recording medium with the use of an electromagnetic ray in which the intensity of the amplitude is spatially modulated.
