Abstract
Disclosed is an actinic ray curable ink-jet ink comprising a cationically polymerizable compound including a cationically polymerizable epoxy compound and a cationically polymerizable oxetane ring-containing compound, wherein the actinic ray curable ink-jet ink contains the cationically polymerizable epoxy compound in an amount of from 35 to 95% by weight based on the total amount of cationically polymerizable compound, the cationically polymerizable epoxy compound having a solubility parameter (sp value) of from 10 to 20, and the cationically polymerizable oxetane ring-containing compound having a solubility parameter (sp value) of from 5 to 8.0, and wherein the actinic ray curable ink-jet ink has a viscosity at 25° C. of 5 to 50 mPa·s.
