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.
本发明公开了一种新型液态光活性不对称丙烯酸酯化合物,该化合物含有硫、芳香族和可选溴,具有高动态范围灵敏度。该丙烯酸酯化合物是光成像系统的单体。在一个实施例中,当约 2-8%(重量)的丙烯酸酯化合物溶解在双组分聚氨酯基质体系中,并加入到通过双组分聚氨酯基质体系反应形成的光学制品中时,光学制品的灵敏度约为 4 或更高,在光学制品形成过程中的收缩率约为 0.05%,而使用商用单体丙烯酸三溴苯酯时,灵敏度为 2.26,收缩率为 0.13%。
