Abstract
An example of a white inkjet ink includes: a non-self-dispersed white pigment; from about 0.005 wt % to about 1 wt %, based on a total weight of the white inkjet ink, of an anionic copolymer dispersant having a weight average molecular weight (Mw) ranging from about 125,000 g/mol to about 30,000,000 g/mol; a polymeric binder; and an aqueous vehicle. The white inkjet ink may be used in a textile printing kit.
