Abstract: The present disclosure is drawn to aqueous pigment dispersions. In one example, an aqueous pigment dispersion can include from 40 wt % to 90 wt % water, from 2 wt % to 30 wt % organic co-solvent, from 7.5 wt % to 30 wt % copper phthalocyanine pigment, from 0.5 wt % to 5 wt % styrene-acrylic dispersant, and from 0.5 wt % to 5 wt % hydrophilic polyurethane dispersant having a weight average molecular weight from 10,000 Mw to 30,000 Mw. The styrene-acrylic dispersant and the hydrophilic polyurethane dispersant can be present at a weight ratio from 1:10 to 2:1.

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.

Abstract: A magenta pigment dispersant can include a mixture of quinacridones including a first quinacridone including two nitrogen- and aromatic-containing pendant groups and a second quinacridone with one nitrogen- and aromatic-containing pendant group.

Abstract: An example of an inkjet composition includes a colorant, a density modifier selected from the group consisting of a triiodo amino derivative of isophthalic acid, a mixture of polysucrose and sodium diatrizoate, colloidal silica particles coated with polyvinylpyrrolidone, and combinations thereof; and an aqueous vehicle. The inkjet composition may be inkjet printed on a substrate, using a thermal or piezoelectric printer.

Abstract: Yellow inkjet inks are disclosed. In an example, an inkjet ink composition comprises: at least one colorant comprising at least one yellow pigment; at least one solvent comprising at least one triol; water; and at least one binder. The binder comprises a polyurethane-based binder dispersion, which comprises water and a polyurethane.

Abstract: An aqueous radiation curable dispersant formulation includes water and styrene acrylic resin stabilized thioxanthone derivative photoinitiator particles dispersed in the water. The styrene acrylic resin stabilized thioxanthone derivative photo initiator particles have a volume-weighted mean diameter of less than 40 nm. The styrene acrylic resin stabilized thioxanthone derivative photo initiator particles include a water-insoluble, thioxanthone derivative photoinitiator core having one, two, or three units. When the water-insoluble, thioxanthone derivative photoinitiator core includes two units or three units, the units are covalently bonded together.
