An ink jet-recording ink capable of being cured through the irradiation with a radioactive ray, in which the ink jet-recording ink comprises a coloring material, a polymerizable compound and a polymerization initiator system, wherein the polymerization initiator system comprises a polymerization initiator and at least one co sensitizing agent selected from the group consisting of compounds represented by the foregoing general formulas (i) to (iv) and (vii) to (ix), as well as a method for preparing a lithographic printing plate comprises the steps of (1) A step for injecting an ink jet-recording ink as set forth in claim 1 on the surface of the substrate; and (2) A step for curing the ink by the irradiation of the substrate carrying the injected ink thereon with a radioactive ray to thus form an image of cured ink on the substrate. The ink is highly sensitive to a radioactive ray, permits the formation of a high quality image and has excellent storage stability. In addition, the method permits the formation of a high quality image excellent in the printing durability.
一种可通过放射性射线照射固化的喷墨记录墨水,其中喷墨记录墨水包括着色材料、可聚合化合物和聚合引发剂体系、其中,聚合引发剂系统包括聚合引发剂和至少一种从由上述通式(i)至(iv)和(vii)至(ix)所代表的化合物组成的组中选出的辅助敏化剂,以及制备平版印刷板的方法,该方法包括以下步骤 (1) 将权利要求 1 所述喷墨记录墨水注入基底表面的步骤;(2) 用放射性射线照射承印物,使油墨固化,从而在承印物上形成固化油墨的图像。这种油墨对放射性射线高度敏感,可以形成高质量的图像,并具有出色的储存稳定性。此外,该方法还能形成高质量的图像,印刷耐久性极佳。
