NEAR INFRARED SENSITIVE PHOTOPOLYMER AND HOLOGRAPHIC PHOTOPOLYMER DISPERSED LIQUID CRYSTAL MATERIALS MADE THEREWITH

摘要

The present invention is concerned with photopolymers sensitive to nearinfrared radiation for initiating polymerization, and to applications of suchphotopolymers, like holographic polymer dispersed liquid crystal materials (H-PDLC) formaking optical devices. The invention also relates to holographic polymerdispersedliquid crystal materials having improved switching speeds.
