To provide a photopolymerization sensitizer which will not cause problems of dusting or coloring of a cured product by 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 imparts a practically sufficient photo-curing rate.
An oligomer of a 9,10-bis(substituted oxy)anthracene compound having repeating units represented by the following formula (1):
wherein n represents a repetition number and is from 2 to 50, each of X and Y which may be the same or different, is a hydrogen atom, a C1-8 alkyl group or a halogen atom, and A is a bivalent substituent.
提供一种光聚合增感剂,该增感剂不会因添加剂(如光聚合增感剂)在固化物表面的渗出(如在光固化时或在固化物储存期间的开花)而导致固化物的起尘或着色问题,并能提供实际上足够的光固化率。
具有下式(1)所代表的重复单元的 9,10-双(取代氧基)蒽化合物的低聚物:
其中 n 代表重复数,从 2 到 50,X 和 Y 可以相同或不同,各自为氢原子、C1-8 烷基或卤素原子,A 为二价取代基。
