PHOTOPOLYMERIZATION INITIATOR COMPRISING AN ARYLIODONIUM SALT FOR DENTAL PHOTOCURABLE COMPOSITIONS

摘要

(Project) To provide a photopolymerization initiator that exhibits excellent sensitivity to photopolymerization and can ensure sufficient pot life to ambient light, and a dental photocurable composition containing the photopolymerization initiator. (Solution Means) In (c) photoinitiator used for dental photocurable composition, (c-1) a photosensitizer, (c-2) a polymerization accelerator, and (c-3) formula (1): [Formula 1] (wherein R1 represents an organic group bonded to I, R2 represents an alkyl group in which some hydrogen atoms are substituted with fluorine atoms, b represents the number and is an integer of 1 to 5) A photoinitiator containing the photopolymerization initiator, and a dental photocurable composition comprising the photoinitiator.
