Title:
USE OF ARYLVINYL A-CARBONYL ACID ESTER COMPOUND AS PHOTOINITIATOR IN LED PHOTOPOLYMERIZATION AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/169520
Kind Code:
A1
Abstract:
The use of an arylvinyl α-carbonyl acid ester compound (I) as a photoinitiator in LED photopolymerization and a preparation method therefor, which relate to the field of polymer photocuring, and are provided on the basis of the problems that an existing photoinitiator has a weak initiation capability under an LED light source, the color of a cured film is relatively deep and cannot be used for deep polymerization, etc. The initiator has a certain absorption in the visible light area, such that the initiator has a relatively high initiation efficiency under an LED light source; moreover, the initiator also has a good photo-bleaching performance, such that the initiator can be used in colorless polymerization and deep polymerization to facilitate the development of the LED photopolymerization industry.
