NEAR INFRARED SENSITIVE PHOTOPOLYMERIZABLE COMPOSITION

摘要

The invention is concerned with a photopolymerizable composition sensitive to near infrared radiation, comprising (a) a photopolymerizable monomer or oligomer, or a mixture thereof, capable of forming a polymer having predetermined optical properties; (b) a photoinitiator sensitive to near infrared radiation; and (c) a filler having optical properties selected to contrast with the optical properties of the polymer. The composition of the invention is particularly useful for producing holographic polymer dispersed liquid crystal materials having improved switching characteristics.
