Document Type and Number:
WIPO Patent Application WO/2019/208321
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide a photopolymerizable composition which can act as a photopolymerization sensitizer that is active against light having a wavelength falling within the wavelength range from 300 to 500 nm, and which has such a property that a cured article produced by polymerizing a photopolymerizable composition containing the photopolymerization sensitizer is rarely discolored.
[Solution] A photopolymerization sensitizer composition which is characterized by comprising a photopolymerization sensitizer comprising an alkoxyanthracene compound represented by general formula (1) and a singlet oxygen quencher; and a photopolymerizable composition which contains the photopolymerization sensitizer composition. (In general formula (1), n represents an integer of 1 or 2; R represents an alkyl group having 1 to 12 carbon atoms; and X represents any one of a hydrogen atom and an alkyl group having 1 to 8 carbon atoms.)
