肟酯光引发剂
摘要：
本发明涉及一种肟酯光引发剂。本发明涉及式(I)、(II)和(III)的化合物，其中R1、R2、R′2和R″′2为例如C1-C20烷基，条件是R1、R2、R′2和R″′2中至少一个带有规定的取代基；R3、R4和R5例如彼此独立地为氢或限定的取代基，条件是R3、R4或R5中至少一个不是氢或C1-C20烷基；R6，R7，R8，R′7，RV，R′8，R″6，R″7，R″′6和R″′7例如彼此独立地具有对于R3、R4和R5给出的含义之一；R9为例如C1-C20烷基，其在光聚合反应中显示出非常好的性能。
摘要（英）：

The invention relates to oxime ester photoinitiators, and relates to compounds of formula (I), (II), and (III), wherein R1, R2, R2' and R2'' for example are C1-C20alkyl, provided that at least one of R1, R2, R2' and R2'' carries a specified substituent; R3, R4, and R5 for example independently of one another are hydrogen or a defined substituent provided that at least one of R3, R4 or R5 is other than hydrogen or C1-C20alkyl; R6, R7, R8, R7', RV, R8', R6'', R7'', R6'' and R7'' for example independently of one another have one of the meanings as given for R3, R4, and R5; and R9 for example is C1-C20alkyl; exhibit an unexpectedly good performance in photopolymerization reactions.
