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

摘要

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