DENTAL PHOTOCURABLE COMPOSITIONS COMPRISING PHOTOPOLYMERIZATION INITIATOR COMPRISING AN ARYLIODONIUM SALT
The present invention provides a photopolymerization initiator capable of exhibiting excellent sensitivity to photopolymerization and ensuring a sufficient pot life under ambient light, and a dental photocurable composition comprising the photopolymerization initiator. More specifically, the present invention provides a photopolymerization initiator (c) used in a dental photocurable composition, comprising: (c-1) a photosensitizer, (c-2) a polymerization accelerator, and (c-3) an aryliodonium salt represented by the formula (1): [Chemical Formula 1] [(R1)<sub>2</sub>I]<sup>+</sup>[(R2)<sub>b</sub>PF<sub>6-b</sub>]<sup>-</sup> .... (1)wherein, R1 represents an organic group bonded to I, R2 represents an alkyl group in which a part of hydrogen atoms is substituted with a fluorine atom, and b represents the number thereof which is an integer of from 1 to 5, and a dental photocurable composition comprising the photopolymerization initiator..
