Title:
PHOTOPOLYMERIZATION INITIATOR
Document Type and Number:
WIPO Patent Application WO/2024/085227
Kind Code:
A1
Abstract:
[Problem] The present invention addresses the problem of providing a photopolymerization initiator which is unlikely to be affected by oxygen inhibition, exhibits good photoinitiation properties even in the air, has high sensitivity to long wavelength light rays, and can suppress odors and bleeding out in an obtained cured product. [Solution] Provided is a photopolymerization initiator which has, in the molecule, one or more benzopheno groups and one or more hetero atom-containing saturated or unsaturated cyclic substituent groups having 5 or more ring-forming atoms. One or more carbon atoms in an aryl group in one or more benzopheno groups is bonded to one or more hetero atom-containing saturated or unsaturated cyclic substituent groups having 5 or more ring-forming atoms via a carboxylic acid ester group or a carboxylic acid amide group.
