Patent ID: 11608316

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), R1, R2, R3, R5 and R6 represent a hydroxy group or an alkoxy group; the R4's independently represent an organic group containing a thioether bond; R7 and R9 independently represent a hydrogen atom or an alkyl group with 1 to 4 carbons; R8 represents 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.
