The ink of the invention comprises at least a pigment, a polymeric dispersant, a solvent and an actinically or thermally cur - c:::, able silicone- containing binder polymer including ethylenically unsaturated groups and segments derived from at least one silicone- ei containing vinylic monomer or macromere. The ink of the invention is characterized by having capability to be cured actinically or 0 theimally to form a colored coat on a silicone hydrogel contact lens, wherein the ink is characterized by having an longer print life using a pad-printing system by at least 30% comparing to the ink which has the same composition except of no polymeric dispersant, wherein ink life is a number of printed parts that can be achieved in a print cycle.
