应用
Application

磺酸肟酯是一种在紫外光照射下，能产生磺酸的化合物。这种化合物产生的酸是一种光可控酸，可导致酸敏感物质发生聚合、交联或分解反应。它可以用于阳离子光固化体系和化学增幅酸敏成像体系。

Under UV irradiation, the compound can produce sulfonic acid, which is a light controllable acid and can lead to polymerization, crosslinkingreaction or decomposition of the acid sensitive material. It can be used in cationic photocuring system and chemical acid agile amplification imagery system.
