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