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. |
