Abstract
An example of a white inkjet ink includes: a non-self-dispersed white pigment: from about 0.01 wt % active to about 5 wt % active, based on a total weight of the white inkjet ink, of a first anionic dispersant that is a copolymer having a weight average molecular weight (Mw) ranging from about 125.000 g/mol to about 30,000,000 g/mol: from about 0.01 wt % active to about 5 wt % active, based on the total weight of the white inkjet ink, of a second anionic dispersant that is a copolymer having a weight average molecular weight (Mw) ranging from about 700 g/mol to about 30.000 g/mol: a rheology modifier: a polymeric binder; and an aqueous vehicle.
Claims15
