Title:
NOVEL COMPOUND, PHOTOPOLYMERIZATION INITIATOR CONTAINING SAID COMPOUND, AND PHOTOSENSITIVE RESIN COMPOSITION CONTAINING SAID PHOTOPOLYMERIZATION INITIATOR
Document Type and Number:
WIPO Patent Application WO/2019/168089
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a novel compound which absorbs long-wavelength active energy rays and generates with high-efficiency radicals and strong bases, and which has excellent reaction efficiency in a base generating chain reaction; a photopolymerization initiator which contains said compound; and a photosensitive resin composition which contains said photopolymerization initiator. This novel compound is represented by formula (1). (In formula (1), R1, R2, R3, R5 and R6 independently represent a hydroxyl group, an alkoxy group, or an organic group other than those substituents. The R4's independently represent an organic group including a thioether bond. 'A' represents a substituent represented by formula (1-1) or (1-2). (In formula (1-1), R7 and R8 independently represent a hydrogen atom, an alkyl group or a heterocyclic group. In formula (1-2), R9 and R10 independently represent an amino group or a substituted amino group.))
