Abstract
An iodonium salt compound which is colored little, can be easily synthesized in high yield, is highly sensitive to irradiation with actinic energy rays such as light, electronic beams, or X-rays, is highly soluble in monomers, and is lowly toxic; and a photocurable composition which can cure in a short time even when the counter anion is a hexafluorophosphonate, tetrafluoroborate, etc., regardless of whether it is clear or pigmented, and which gives a cured object having excellent properties. The photocurable composition is prepared by compounding an iodonium salt compound represented by the general formula (I) with a cationically polymerizable compound, a sensitizer, etc.
