Title:
PHOTOPOLYMERIZATION INITIATOR
Document Type and Number:
WIPO Patent Application WO/2021/117880
Kind Code:
A1
Abstract:
[Problem] The present invention addresses the problem of providing a photopolymerization initiator that is highly compatible with a monomer used together therewith, has an inhibited odor or bleed-out problem, and has high sensitivity to long-wavelength light. [Solution] The present invention has been achieved through discovery of a photopolymerization initiator having, in the molecule, at least one ethylenically unsaturated bond and at least one photopolymerization-initiating functional group. As the ethylenically unsaturated bond, at least one selected from an acrylamide group, an acrylate group, a vinyl group, an allyl group, a maleimide group, and the like can be suitably used. As the photopolymerization-initiating functional group, a benzophenone compound having a specific structure can be suitably used. [Selected figure] None
