PHOTOPOLYMER BLEND WITH LOW CROSSLINKING DENSITY SUITABLE FOR BRIGHT HOLOGRAM WITH HIGH DIFFRACTION EFFICIENCY

摘要

PURPOSE: A photopolymer blend is provided to be processed without thermal post treatment or wet-chemical post treatment, and to obtain colorless hologram with high diffraction efficiency after exposure and high brightness.;CONSTITUTION: A photopolymer blend comprises (A) a three-dimensionally crosslinked organic polymer or precursor thereof as a matrix, (B) a compound including a group reactive with an ethylenically unsaturated compound through polymerization under the action of actinic radiation, which is present in a solution or dispersion form, and (C) at least one photoinitiator.;COPYRIGHT KIPO 2010
