    Abstract: An ink composition includes colorant, hydroxylated and non-hydroxylated co-solvents, and water. A weight percent ratio of hydroxylated to non-hydroxylated co-solvents ranges from 46:54 to about 62:38. The composition also includes an acid and a polyurethane copolymer binder. The acid is selected from the group consisting of oleic acid, linoleic acid, undecanoic acid, dodecanoic acid, tridecanoic acid, and combinations thereof. The binder is formed from the polymerization of a diisocyanate and at least three diols including a first diol containing a hydrophilic stabilizing group, and a second diol having less than 8 atoms in a backbone chain between two hydroxyl groups. A mole percentage of the second diol is at least 30% of a total mole percentage of diol monomers in the binder. An acid number of the binder ranges from 50 to 75. The composition also includes lithium present in an amount ranging from about 50 to about 400 ppm.

    Abstract: A print head module for delivering ink to a print head comprising a module venting system comprising a one-time vent built into the interior of the print head module in which, when an amount of ink comes in contact with the one-time vent, air is prevented from passing through the one-time vent. A system for delivering ink to a print head comprising a print head, a external reservoir of ink, and a print head module comprising a one-time vent built into the interior of the print head module and fluidly coupling the print head to the external reservoir of ink, in which, when an amount of ink comes in contact with the one-time vent within the print head module, air is prevented from passing through the one-time vent.

    Abstract: An ink-jet ink is disclosed which comprises polymer-dispersed pigment particles in a liquid vehicle, wherein the polymer has an acid number of at least about 175 and comprises polymer molecules having anionic groups and hydrogen bond-forming groups. The anionic groups and the hydrogen bond-forming groups are configured on each of the polymer molecules to permit association of the anionic groups with cationic groups on a print medium, and to also permit the hydrogen bond-forming groups on neighboring polymer molecules to interact pair wise with each other, as the liquid vehicle dries and/or is absorbed into the medium.
