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 a wavelength range of from 300 to 500 nm, and which has such a property that coloring of a cured product produced by polymerizing a photopolymerizable composition containing the photopolymerization sensitizer is less.
A photopolymerization sensitizer composition characterized by comprising a photopolymerization sensitizer containing an alkoxyanthracene compound represented by the formula (1) and a singlet oxygen quencher; and a photopolymerizable composition containing the photopolymerization sensitizer composition:
in the formula (1), n represents an integer of 1 or 2; R represents a C1-12 alkyl group; and X represents a hydrogen atom or a C1-8 alkyl group.
本发明的目的是提供一种可光聚合组合物,该组合物可作为光聚合敏化剂,对波长在300至500纳米范围内的光具有活性,并且具有这样一种特性,即通过聚合含有该光聚合敏化剂的可光聚合组合物而生产的固化产品着色较少。
一种光聚合增感剂组合物,其特征在于包括含有式(1)表示的烷氧
蒽化合物和单线态氧淬灭剂的光聚合增感剂;以及含有该光聚合增感剂组合物的可光聚合组合物:
式(1)中,n 代表 1 或 2 的整数;R 代表 C1-12 烷基;X 代表氢原子或 C1-8 烷基。
