An oxime ester compound represented by general formula (1) [wherein R1 to R4 are each OR11, COOR11, or the like; R11 is a hydrogen atom, a C1-20 alkyl group, a C6-30 aryl group, a C7-30 arylalkyl group, or a C2-20 heterocyclic group, the hydrogen atoms of these groups being optionally replaced by -CR21=CR22R23, -CO-CR21=CR22R23, -O-CO-CR21=CR22R23, or the like (wherein R21 to R23 have the same meanings as defined above for R11); X is a sulfur atom, NR33 (wherein R33 is a hydrogen atom, a C1-20 alkyl group, or the like), or the like; a is an integer of 0 to 4; b is an integer of 1 to 5; and at least one of the R4 moieties is a group having -CR21=CR22R23, -CO-CR21=CR22R23, -O-CO-CR21=CR22R23 or the like]. |
