Multi-functionalized benzoylformicacid hydroxy-ketone ester compounds and photoinitiator containing compounds

Abstract

The invention discloses novel Multi-functionalized benzoylformicacid hydroxy-ketone ester compounds, phosphorus-acyl derivatives, a combination containing the compounds, and a photoinitiator being used for photopolymerization of an alkene unsaturated compound system and containing the compounds. The compounds contain at least one of compounds shown in the following general formula I-III or any combination comprising the compounds shown in the following general formula I-III. The compounds can be used as alkene unsaturated compounds or the photoinitiator or photopolymerization of a mixt6ure containing the compounds, and can be combined with another photoinitiator and / or other additives for use.

Description

Multifunctional hydroxy ketone benzoylformate compound and photoinitiator containing the compound 【Technical field】 The present invention describes a series of benzoylformic acid hydroxyketoester aromatic ketone compounds, their phosphono derivatives, compositions containing these compounds, and photopolymers containing such compounds for the photopolymerization of ethylenically unsaturated compound systems. Initiator. 【Background technique】 Benzoylformate (methylphenylgloxylate) compounds and α-hydroxyketone (hydroxy-ketone) type structures have been proved to be effective free radical photoinitiators, some of which have been commercialized, such as DarocurMBF, Darocur1173, Darocur2959, and Irgacure184. Recently, Ciba Corporation (now belonging to BASF Corporation) proposed the photoinitiator compound [US Patent 2005 / 0228062A1, Chinese Patent 1649905A, and U.S. Patent 2009 of the following general structure on the basis of modifying the benzoylformate structure. / 00927...

AI Technical Summary

Problems solved by technology

It is worth noting that the composite structure of benzoylformate compounds and α-hydroxyketone compounds, that is, multiple photoactive functionalized benzoylformate hydroxyketone compounds, has not been reported in the literature. We found that this type of new structure is very easy prepared and can be used as a photoinitiator for free radical polymerization of ethylenically unsaturated compounds
