Document Type and Number:
WIPO Patent Application WO/2020/004601
Kind Code:
A1
Abstract:
Provided are: an oxime ester compound useful as a photopolymerization initiator used in a polymerizable composition; and a photopolymerization initiator containing the oxime ester compound. This compound has a group represented by general formula (I), and a photoradical cleavable group that does not have an oxime ester group, in the same molecule. In general formula (I), R1 and R2 each independently represent a hydrogen atom, a halogen atom, a nitro group, a cyano group, or the like, one or more of the hydrogen atoms in the groups represented by R1 and R2 may be substituted with a halogen atom, a nitro group, a cyano group, or the like, one or more of the methylene groups in the groups represented by R1 and R2 may be substituted with -O-, -CO-, -COO-, -OCO-, -NR3-, or the like, provided that oxygen atoms are not adjacent to each other, R3 represents a hydrogen atom or a hydrocarbon group having 1-20 carbon atoms, n represents 0 or 1, and * represents a bond.
