Ink composition, inkjet recording method, printed material, process for producing lithographic printing plate, and lithographic printing plate
Abstract:
An ink composition is provided that includes a cationically polymerizable compound (a), a compound (b) that generates an acid when exposed to radiation, a colorant (c), and a salt of a weak acid having a pKa of 4 to 8 (d). There is also provided an inkjet recording method that includes a step of discharging the ink composition onto a recording medium, and a step of irradiating the discharged ink composition with radiation so as to cure the ink composition.
Abstract(Chinese):

提供一种油墨组合物，其包含阳离子聚合性化合物（a），暴露于辐射时产生酸的化合物（b），着色剂（c）和pKa为4-8的弱酸盐（ d）。 还提供了一种喷墨记录方法，其包括将油墨组合物排出到记录介质上的步骤，以及用放射线照射排出的油墨组合物以固化油墨组合物的步骤。
