    • A photopolymerization initiator comprising an iodonium salt compound; and a photocurable composition containing the compound. The composition is a photocurable cationic composition which cures in a short time upon irradiation with actinic energy rays. They are based on the following findings: (1) a colorless lowly toxic iodonium salt compound can be easily synthesized in high yield when a specific substrate is used as a starting material; (2) a photocurable composition curing in a short time to give a cured article having excellent material properties is obtained by using the iodonium salt compound in combination with a sensitizer; and (3) a highly sensitive photocurable composition which upon irradiation with actinic energy rays cures in a short time to give a cured article having excellent material properties is obtained by using a compound having a group functioning as a cationic photopolymerization initiator, a sensitizing group accelerating the phtoinitiated cationic reaction, and a cationically polymerizable group in the same molecule.
    • 包含碘鎓盐化合物的光聚合引发剂; 和含有该化合物的光固化性组合物。 该组合物是可光固化的阳离子组合物,其在用光化能量射线照射时在短时间内固化。 它们基于以下发现:(1)当使用特定的底物作为起始材料时,可以容易地以高产率合成无色低毒碘鎓盐化合物; (2)通过将碘鎓盐化合物与敏化剂组合使用,可以获得在短时间内固化以得到具有优异材料性质的固化物的光固化性组合物; (3)一种高灵敏度的光固化性组合物,其通过使用具有作为阳离子性光聚合引发剂的基团的化合物,在短时间内固化而得到具有优异的材料性质的固化物的光敏性组合物, 反式阳离子反应和同一分子中的阳离子聚合性基团。
