Abstract
This compound which has excellent solvent solubility and compatibility with a resin, and which can generate bases and radicals with high efficiency by being irradiated with active energy rays, is represented by formula (1), where, in formula (1), R, R, R, Rand Rrepresent a hydroxy group or an alkoxy group; the R's independently represent an organic group containing a thioether bond; Rand Rindependently represent a hydrogen atom or an alkyl group with 1 to 4 carbons; Rrepresents an alkylene group or an arylene group; and X represents an oxygen atom or a sulfur atom. A photopolymerization initiator can include said novel compound; and a photosensitive resin composition can include said photopolymerization initiator, from which a cured product can be obtained that has high sensitivity and no metal corrosion.
