PROBLEM TO BE SOLVED: To obtain a new O-acyloxime useful as a photopolymerization initiator, having excellent heat stability and storage stability, capable of exhibiting high reactivity in photopolymerization technology, and capable of being easily synthesized and handled. SOLUTION: Compounds of formulas I-IV (R1 in phenyl or the like; R2 is a 2-12C alkanoyl or the like; R3 to R7 are each H, a halogen, a 1-12C alkyl or the like; R1' is a 2-12C alkoxycarbonyl or the like; R4' to R6' are each H, a halogen, a 1-12C alkyl, a cyclopentyl or the like; M is a 1-12C alkylene, cyclohexylene or the like), for example, 1-(4-phenylsulfany-phenyl)-butane-1,2- dione 2-oxime-O-benzoate. The compounds of formula I-IV each is obtained, for example, by reacting the corresponding oxime with an acyl chloride or anhydride in the presence of a base such as a tertiary amine in an inert solvent such as tetrahydrofuran or in a basic solvent such as pyridine. |
