Aromatic ketone oxime photoinitiator compound

Abstract

The invention discloses a kind of compounds with a general formula of I-VIII. The compounds can be singly used as an alkene unsaturated system photopolymerization initiator and also can be combined with another photoinitiator and/or other additives.

Description

【Technical field】 The invention relates to some novel mono- or bifunctional aromatic ketone oxime compounds and the use of the compounds as photoinitiators for radical polymerization of ethylenically unsaturated systems. The characteristic of this type of compound is that not only the structure contains a common C=N-O key group, but also the same substrate is used in the preparation process. 【Background technique】 肟酯类化合物作为光引发剂近年来研究活跃,已有较多专利文献报道,例如专利CN1514845A,CN1720245A,CN101014569A,CN101321727A,CN101679394A,CN101687794A,CN99108598,CN02811675,CN1800885A,CN1928716A,CN101158812A,CN101525393A,CN101634807A,US3558309 . However, although oxime esters have been reported as photoinitiators in the seventies of last century (European Polymer Journal, 1970, 6, 933), and commercial products such as Quantacure PDO have appeared in the early stage, they have real practical value There are very few, which is mainly because the comprehensive performance of the stability and activity of th...
