<p>A water-based lithographic ink composition is described, and contains water, a resin-bonded pigment; a nonionic surfactant, a rewetting agent, and a polymerizable surfactant. The nonionic surfactant is present in an amount such that the dynamic surface tension of the total composition is about 20 to about 40 dynes/cm. The polymerizable surfactant is present in an amount of about 0.5 % by weight to about 2 % by weight of the composition. The ink composition may also contain other, conventional ink component, as desired.</p> |
