Zusammenfassung:	An example inkjet ink composition includes a colorant, an acid, lithium, an organic solvent package, at least 50 wt % water with respect to the weight of the inkjet ink composition, and from about 0.25 wt % to about 2 wt %, with respect to the weight of the inkjet ink composition, of a polyurethane binder. The acid is selected from the group consisting of oleic acid, linoleic acid, undecanoic acid, dodecanoic acid, tridecanoic acid, and combinations thereof. The organic solvent package includes from about 1 wt % to about 12 wt %, with respect to the weight of the inkjet ink composition, of a first solvent having 1 or 2 free hydroxyl groups and 0 to 3 glycol units and from about 0.5 wt % to about 25 wt %, with respect to the weight of the inkjet ink composition, of a second solvent selected from the group consisting of 1-(2-hydroxyethyl)-2-pyrrolidinone, 2-pyrrolidone, glycerol, and combinations thereof.
