Abstract: An ink-jet ink which includes a liquid vehicle and a polymer-dispersed pigment dispersed in the liquid vehicle is disclosed and described. More specifically, the polymer-dispersed pigment can include a pigment encapsulated with a polymer having hydrophilic and hydrophobic moieties. The polymer can be a polymerization product of at least a first monomer having a hydrophilic group, and a second monomer having a hydrophobic group. Further, the polymer can be configured such that the polymer-dispersed pigment is stable in the liquid vehicle at a pH of from about 5.5 to about 8.5. Such polymer-dispersed pigments allow for formation of ink-jet inks with improved options for bleed control mechanisms and increased reliability of ink-jet architecture.

Abstract: An ink composition includes a colorant, a co-solvent, and an acid chosen from oleic acid, linoleic acid, undecanoic acid, dodecanoic acid, tridecanoic acid, and combinations thereof. The ink composition further includes lithium and water. An anti-evaporative layer forms, during uncapped non-use, at an interface between air and the ink composition in an orifice of a nozzle, thereby reducing evaporation of the water from the ink composition.

Abstract: An inkjet ink including a polymer-attached pigment formulated to exhibit a compact configuration and an elongated configuration, which provides the polymer-attached pigment with a variable particle size. The polymer-attached pigment may include a pigment having at least one polymer attached to its surface. The at least one polymer may be formed from a hydrophobic segment and a hydrophilic segment, where the hydrophilic segment is soluble in an aqueous environment and the hydrophobic segment is insoluble in the aqueous environment. The polymer-attached pigment may be dispersed in an ink vehicle to provide a low viscosity inkjet ink. The inkjet ink may optionally include at least one binder formed from a hydrophobic segment and two hydrophilic segments. A method of producing a printed image having good durability and gloss is also disclosed.
