Title:
MIGRATION-RESISTANT PHOTOPOLYMERIZATION SENSITIZER
Document Type and Number:
WIPO Patent Application WO/2020/121544
Kind Code:
A1
Abstract:
[Problem] To provide a photopolymerization sensitizer which imparts sufficient photocuring speed for practical purposes without causing the problem of coloring or powder blowing in cured products due to additives such as the photopolymerization sensitizer bleeding to the surface as a result of blooming or the like when photocuring or during storage of cured products. [Solution] A 9,10-bis(alkoxy carbonyl alkylene oxy)anthracene compound represented by general formula (1) and having an ester group. (In general formula (1), A represents a C1-20 alkylene group, and said alkylene group may be branched by an alkyl group. R represents a C1-20 alkyl group, and said alkyl group may be branched by an alkyl group and may be a cycloalkyl group or a cycloalkyl alkyl group. X and Y may be the same or different, and each represent a C1-8 alkyl group or a halogen atom.
