  • WHITE INKJET INK
    Publication number: 20230265303
    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.

  • WHITE INK COMPOSITIONS
    Publication number: 20220135818
    Abstract: A white ink composition can include an aqueous ink vehicle including water and organic co-solvent, from 5 wt % to 30 wt % white metal oxide pigment, from 0.05 wt % to 1 wt % block copolymer dispersant adsorbed on a surface of the white metal oxide, and from 2 wt % to 30 wt % polyurethane binder. The block copolymer dispersant can have a weight average molecular weight from 5,000 Mw to 20,000 Mw and an acid number from 0 mg KOH/g to 40 mg KOH/g based on dry weight of the block copolymer dispersant.
