[EN] PHOTOPOLYMERIZATION SENSITIZER HAVING MIGRATION RESISTANCE<br/>[FR] SENSIBILISATEUR DE PHOTOPOLYMÉRISATION AYANT UNE RÉSISTANCE À LA MIGRATION<br/>[JA] 耐マイグレーション性を有する光重合増感剤
A photopolymerization sensitizer may not cause problems of dusting or coloring of a cured product due to bleeding of additives such as the photopolymerization sensitizer on the surface, e.g., by blooming at the time of photo-curing or during storage of the cured product, and which provides a practically sufficient photo-curing rate. A 9,10-bis(alkoxycarbonylalkyleneoxy)anthracene compound having ester groups, of formula (I):
wherein A is a C
1-20
alkylene group, optionally branched by an alkyl group, R is a C
1-20
alkyl group, optionally branched by the alkyl group, the C
1-20
alkyl group optionally being a cycloalkyl group or a cycloalkylalkyl group, and X and Y are independently a hydrogen, a C
1-8
alkyl group, or a halogen.
