Abstract
A novel liquid photoreactive asymmetric acrylate compound containing sulfur, aromatic moieties, and optionally bromine, and having high dynamic range sensitivity is disclosed. The acrylate compound is a monomer for a photoimageable system. In one embodiment, when about 2–8% by weight of the acrylate compound is dissolved in a two-component urethane matrix system and incorporated in an optical article formed by reacting the two-component urethane matrix system, the optical article shows a sensitivity of about 4 or more and a shrinkage during the formation of the optical article of about 0.05% versus a sensitivity of 2.26 and a shrinkage of 0.13% when tribromophenyl acrylate, a commercial monomer, was used.
