Abstract
A liquid crystal light composite in which discrete volumes of a liquid crystal material are dispersed in a matrix material is produced by a process in which a reactive additive formulation is added and photopolymerized. The reactive additive formulation includes mono- and multifunctional compounds in specified proportions and a photoinitiator. The reactive additive formulation reduces the operating field and may also improve other electro-optical properties.
