Double functionalized aromatic ketone compounds and photoinitiator containing same

Abstract

The invention discloses a double functionalized aromatic ketone photoinitiator. The photoinitiator contains biphenyl or naphthyl substituted dihydroxy-ketone, diamino-ketone or hydroxyl-ketone and amino-ketone mixed type double functionalized aromatic ketone compounds and related diphenylmethane, diphenyl ether or diphenylamine derivative ethylene oxide or aziridine aromatic ketone double functional group compounds or compositions which contain the compounds. The compounds can be used as the photoinitiator of photopolymerization of an alkene unsaturated compound or a mixture which contains the compound, and the compounds can also be combined with another photoinitiator and / or other additives for use. Compared with a traditional photoinitiator, the compounds do not generate or generate less volatile organic compounds when in use.

Description

【Technical field】 The invention belongs to a difunctional aromatic ketone compound and a photoinitiator containing the aromatic ketone compound used as an ethylenically unsaturated compound system photopolymerization reaction. 【Background technique】 Monofunctional and difunctional α-hydroxyacetophenone and α-aminoacetophenone compounds are commonly used photoinitiators for free radical photopolymerization in the market. 该类化合物已公开于各种专利文献中,例如PCT国际公开号为2008122504A1、2005014515A2和2008084853A1的申请,美国专利4,582,862、4318791、4795766、4,992,547、5,541,308、5,077,402、4,559,371、4,739,052、7482392B2,德国专利2808459和 Japanese patent 2009203299A.
