Actinic ray curable ink-jet ink and printed matter

摘要

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 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, and wherein the cationically polymerizable epoxy compound has a solubility parameter (sp value) of from 10 to 20, and the cationically polymerizable oxetane ring-containing compound has a solubility parameter (sp value) of from 5 to 10.
