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.
一种光聚合敏化剂可以避免因添加剂(如光聚合敏化剂)在表面上渗出而导致的固化产品的粉尘或着色问题,例如在光固化或固化产品存储期间发生的开花现象,并且提供实际上足够的光固化速率。 公式(I)中具有酯基的9,10-双(羧酸酯基烷氧基)蒽化合物,其中A是C1-20烷基,可由烷基支链化,R是C1-20烷基,可由烷基支链化,C1-20烷基可选为环烷基或环烷基烷基,且X和Y分别是氢,C1-8烷基或卤素。
