Abstract: An example of a liquid ink includes a pigment dispersion, a polyurethane dispersion, a polytetrafluoroethylene wax emulsion, a co-solvent, and a balance of water. A particle diameter of a polytetrafluoroethylene wax in the polytetrafluoroethylene wax emulsion is less than 50 nm. Examples of the liquid ink may be incorporated into a thermal inkjet printing system.

Abstract: An inkjet ink can include an ink vehicle and ink solids carried by the ink vehicle. The ink solids can include a pigment, 5 wt % to 40 wt % polymeric binder, and 0.3 wt % to 3 wt % wax. The wax can have a melting point of from 90° C. to 115° C. and an average particle size of from 0.1 μm to 0.5 μm. Further, the wax can include wax particles having a particle size greater than 1 μm but which are present at a quantity no greater than 0.1% of the total number of wax particles based on particle count.

Abstract: An example of a liquid bonding agent, for a liquid ink including a wax emulsion in an amount less than 1% actives, includes a calcium salt, the wax emulsion, an acetylenic surfactant, a glycol, and a balance of water. The wax emulsion is present in the liquid bonding agent in an amount ranging from greater than 0% actives to about 2% actives. The liquid bonding agent is to be digitally printed with a thermal inkjet printhead on a substrate under the liquid ink.
