Abstract: The present invention provides single fluid lithographic printing inks that include a continuous phase and a discontinuous emulsified phase. The continuous phase includes a polymer or mixture of polymers having from about 0.25 to about 15 meq/gram of groups capable of hydrogen bonding with the hydrophilic phase, from about 1.0 to about 3.0 meq/gram of one or more members selected from the group consisting of aromatic groups, cyclic aliphatic groups, and combinations thereof, and from about 0.3 to about 3.0 meq/gram of aliphatic hydrocarbon segments, each independently having from about 8 carbon atoms to about 51 carbon atoms. The emulsified phase includes water and/or a liquid polyol. The invention further provides a method of making a single fluid ink composition and a process of printing using the single fluid ink of the invention with improved resistance to toning.
