Paragraph 0059-0061, (2022/01/08)
The invention belongs to the field of radiation curing new materials, and relates to an aromatic ketone compound, in particular to a monosubstituted or polysubstituted polyfunctional group aromatic ketone compound, a preparation method thereof and a photopolymerization composition containing an ethylenically unsaturated compound system, which takes the compound as an effective component. The invention provides monosubstituted and polysubstituted polyfunctional group aromatic ketone compounds. The polyfunctional group aromatic ketone compounds have a general formula structure as shown in (I). The invention also discloses a preparation method and an application of the polyfunctional aromatic ketone compound. According to the invention, industrial-grade raw materials which are low in cost and easy to obtain are used as a starting point to prepare the monosubstituted or polysubstituted functionalized aromatic ketone compound in a breakthrough way, and the compound is applied to a photoinitiator in radiation curing, so that the problems of toxicity and VOCs pollution of the photoinitiator are solved, and the economic competitiveness of the photoinitiator is strived; the overall cost is reduced, and the photo-initiation efficiency is improved.
