An ink jet-recording ink composition capable of being cured through the irradiation with radiant rays comprises at least a coloring material, a polymerizable compound and a polymerization initiator, wherein the polymerization initiator is a compound possessing, in the molecule, a polymerizable structure represented by the following general formula (I):
Wherein Ra and Rb each independently represents a hydrogen atom, a halogen atom, a cyano group or an organic group; Z represents CN or COY; X represents a group or a halogen atom bonded to the a -carbon through a hetero atom; and Y represents a group or a halogen atom bonded to the carbonyl group through a hetero atom. The ink composition is highly sensitive to the irradiation with radiant rays, permits the formation of a high quality image and is excellent in the storage stability. The composition can likewise be used in the preparation of a lithographic printing plate, which is free of any developing treatment and permits the formation of images having high printing durability and high quality.
一种可通过辐射线照射固化的喷墨记录墨
水组合物至少包括一种着色材料、一种可聚合化合物和一种聚合
引发剂,其中聚合
引发剂是一种在分子中具有由以下通式 (I) 表示的可聚合结构的化合物:
其中 Ra 和 Rb 各自独立地代表氢原子、卤素原子、
氰基或有机基团;Z 代表 CN 或 COY;X 代表通过杂原子与 a - 碳键合的基团或卤素原子;Y 代表通过杂原子与羰基键合的基团或卤素原子。这种油墨组合物对辐射线的照射非常敏感,可以形成高质量的图像,并具有出色的储存稳定性。该组合物还可用于平版印刷板的制备,无需任何显影处理,可形成具有高印刷耐久性和高质量的图像。
