HOLOGRAM COMPOSITION, HOLOGRAM COMPOSITION, OPTICAL ELEMENT FOR A HOLOGRAM, OPTICAL PREPARATION AND THE OPTICAL COMPONENTS USED AND PROCEDURES FOR ESTABLISHING A HOLOGRAM APPROVAL

摘要

The preparation of a hologram recording composition is capable of further improving bending properties and the transparency of a hologram.This technology provides a hologram recording composition which has at least one chrome dye, the discoloured body of which has a primary and/or secondary amino group structure,an epoxy monomer and a polymerisation initiator. This technology also provides a hologram recording medium containing a light sensitive layer containing at least one chrome dye whose discoloured body has a primary and/or secondary amino group structure,contains an epoxy monomer and a polymerisation initiator. In addition, this technology also provides an optical element for a hologram using the hologram recording medium.In addition, this technology also provides an optical device and an optical component that uses the optical element for a hologram.This technology also provides a process for the production of a hologram bending grid, which includes the process of selectively reacting the hologram recording medium by means of an electromagnetic beam with a spatially modulated amplitude.
