A photo-curing ink composition comprises a photocation-polymerizable substance, a photocation polymerization initiator, and a surfactant having a functional group. The surfactant is selected and the amount thereof is adjusted so that the acid value per 100 g of the ink composition is not more than 150 mg KOH. The surfactant is selected and the amount thereof is adjusted so that the amine value per 100 g of the ink composition is not more than 23 mg KOH. The ink composition is excellent in dispersion performance, storage stability, and curing performance.
一种光固化油墨组合物包括一种可光致发光聚合的物质、一种光致发光聚合
引发剂和一种具有官能团的表面活性剂。选择表面活性剂并调整其用量,使每 100 克油墨组合物的酸值不超过 150 毫克 KOH。选择表面活性剂并调整其用量,使每 100 克油墨组合物中的胺值不超过 23 毫克 KOH。该油墨组合物在分散性能、储存稳定性和固化性能方面都非常出色。
