PHOTOPOLYMERIZABLE COMPOSITION SENSITIVE TO LIGHT IN A GREENTO INFRARED REGION OF THE OPTICAL SPECTRUM

摘要

The present invention is concerned with photopolymer materials sensitive to infrared, near infrared, red and green light radiation for initiating polymerization a nd to applications of such photopolymer, like holographic polymer dispersed liquid crystal (H- PDLC) or reversible dye doped photopolymer (RDDP) materials, for making optical devices. The invention relates to holographic polymer dispersed liquid cryst al and reversible dye materials having improved electrical and optical switching properties.
