肟酯化合物以及含有该化合物的光聚合引发剂
摘要：
下述通式（1）表示的肟酯化合物。式中，R1～R4表示OR11、COOR11等，R11表示氢原子、C1～20的烷基、C6～30的芳基、C7～30的芳烷基或C2～20的杂环基，这些基团的氢原子还可以被－CR21＝CR22R23、－CO－CR21＝CR22R23、－O－CO－CR21＝CR22R23等取代（R21～R23与R11相同）；X表示硫原子、NR33（R33为氢原子、C1～20的烷基等）等；a表示0～4的整数；b表示1～5的整数，R4中的至少一个是具有－CR21＝CR22R23、－CO－CR21＝CR22R23、－O－CO－CR21＝CR22R23等的基团。
摘要（英）：

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.
