ABSTRACT:
The present invention provides a volume type hologram recording photosensitive composition. A type (i) composition comprises one or more photopolymerizable compounds, a heat-curable compound and a heat-curing crosslinking agent, wherein the heat-curing crosslinking agent is a latent heat-curing crosslinking agent which is not reacted in an interference exposure process, is not reacted at the heating temperature used in a refractive index-modulation promoting process and becomes active at the heating temperature used in a heat-curing process. A type (ii) composition further comprises a binder resin beside the type (i) volume type composition.
