Abstract: An ink composition comprises a colorant and an additive. The additive is selected from the group consisting of first dispersants synthesized from an aromatic mercaptan, a hydrophilic monomer, a hydrophobic polymeric reactant having a siloxyl substituent and a first stabilizing reactant; second dispersants synthesized from a non-aromatic mercaptan, a hydrophilic monomer, a hydrophobic polymeric reactant having a siloxyl substituent, and a second stabilizing reactant selected from the group consisting of nonylphenoxy (PEG)4-6 methacrylate, nonylphenoxy (PPG)4-6 methacrylate, nonylphenoxy (PEG)4 6 acrylate, nonylphenoxy (PPG)4-6 acrylate and mixtures thereof; humectant mixtures comprising a bis-hydroxy terminated thioether, a lactam, and a compound selected from the group consisting of polyalkylene glycols, polyol/alkylene oxide condensates and mixtures thereof; and mixtures thereof.

Abstract: Wet-rub resistant ink compositions are described and the ink compositions have a binder material or binder composition which may be prepared from monomeric precursors which include vinyl halides, acrylates, alkylol amides and urethanes.
