PHOTOPOLYMERIZATION INITIATOR

摘要

PROBLEM TO BE SOLVED: To provide a new photopolymerization initiator having an improved solubility in an aqueous alkali solution, and to provide a photosensitive resin composition forming little sludge using the photopolymerization initiator.

SOLUTION: The photopolymerization initiator comprises a specific aryl-bisimidazolium salt represented by formula (I) or (II) in which at least one N in an imidazole ring has a salt structure. The photosensitive resin composition comprises the photopolymerization initiator.
