<p>Provided is an actinic energy radiation curable ink-jet ink, an ink-jet recording method, and printed matter satisfying ink storage stability, ejection stability, weather resistance, flexibility, safety, odorless properties. An actinic energy radiation curable ink-jet ink comprises a cationically polymerizable compound and a photo-cationic polymerization initiator, wherein the cationically polymerizable compound comprises a vinyl ether group as a. reactive group, the photo-cationic polymerization initiator is a photo acid generator, a amount of generation of protonic acid from the photo acid generator is 1 x 10 -4 mol/L or less, and comprising a radical polymerization inhibitor; wherein the amount of generation of protonic acid is defined as a difference of a hydrogen ion concentration (mol/L) in dioxane solution between immediately after preparation and after refluxing when 0.02 mol/L of the photo acid generator in dioxane solution are refluxed 20 hours under atmospheric pressure.</p> |
