    Abstract: An object of the present invention is to provide an active energy ray-curable lithographic ink that exhibits good adhesion to a plastic film and does not cause a decrease in the adhesion capability even during hot-water treatment. The present invention encompasses a printing ink that includes (a) a urethane (meth)acrylate and (c) another polymerizable monomer, wherein the printing ink has an ink tack value of 5.0 or more and 18.0 or less and a viscosity (C) and a viscosity (B) that are both 5 Pa·s or more and 100 Pa·s or less, as measured at a rotational speed of 20 rpm and a rotational speed of 50 rpm respectively at 35° C., using a cone-plate rotating viscometer, and wherein the viscosity ratio (B)/(C) is 0.60 or more and 1.00 or less.
