Multi-functional group type aromatic ketone compound and photoinitiator containing same

Abstract

The invention discloses a multi-functional group type aromatic ketone compound (shown as in general formulas I-VI), a photoinitiator containing the same and a synthesizing method of the multi-functional group type aromatic ketone compound.

Description

【Technical field】 The invention relates to some multifunctional aromatic ketone compounds and photoinitiators containing the compounds. 【Background technique】 A prominent problem encountered in the increasing practical application of various ultraviolet (UV) radiation curing systems is that, while trying to achieve the required light curing efficiency, it is also trying to reduce or eliminate the adverse environment that its products may bring. and health risks. At the level of the photoinitiator that must be used, this correspondingly requires that the photoinitiator has both high initiation activity and low volatile organic compound (Volatile Organic Compounds, VOC for short) residue after the job is completed. A potential strategy in this field is to research and develop new photoinitiators with multiple photoactive initiation sites, which can initiate the rapid polymerization of ethylenically unsaturated systems and lead to the formation of films with higher crosslink d...
