<p>An actinic radiation curable jet-printing ink containing a polymerizable monomer component, characterized in that the polymerizable monomer component comprises 95 to 99.99wt% of a monofunctional monomer and 0.01 to 5wt% of a polyfunctional monomer and that a 10-µm thick cured film formed by using the ink exhibits a ductility exceeding 120% when stretched at 170ºC at a strain rate of 2/min.</p>
