摘要： The present disclosure provides non-Newtonian inkjet inks and related methods. In one example, a non-Newtonian inkjet ink can comprise a dispersion of metal oxide particles in an amount ranging from 0.1% to 10% by weight based on the total weight of the non-Newtonian inkjet ink; a salt in an amount of 0.05% to 10% by weight based on the total weight of the non-Newtonian inkjet ink; and an organic solvent. Additionally, the metal oxide can form a structured network in a presence of the salt and the inkjet ink can have a dynamic viscosity ranging from 25 cps to 10,000 cps at shear rate of 5 s−1 and a dynamic viscosity ranging from 1 cps to 50 cps at a shear rate of 10,000 s−1.

摘要： The present disclosure provides an example of a white ink. The ink includes an aqueous ink vehicle and from 5 wt % to 60 wt % of a white flocculated colorant mass. The white flocculated colorant mass can include white metal oxide pigment having an average particulate size from 100 nm to 2,000 nm, silica coated on the white metal oxide pigment to form a silica-coated pigment, and a polymeric dispersant associated with a surface of the silica-coated pigment.

摘要： The present disclosure provides an example where a white ink can include an aqueous ink vehicle and from 5 wt % to 60 wt % of a white flocculated colorant mass. The white flocculated colorant mass can include white metal oxide pigment, an alumina coating, and polymeric dispersant associated with a surface of the alumina-coated pigment. The white metal oxide pigment can have an average particulate size from 100 nm to 2,000 nm. The alumina coating on the white metal oxide pigment can form an alumina-coated pigment where the alumina coating is predominantly alumina, and the white metal oxide pigment content to alumina content can be from 99:1 to 9:1 by weight.

摘要： In a 3D printing method example, color is added to a part. A build material is applied, and is pre-heated to a temperature ranging from about 50 C to about 400 C. A black ink, including an infrared absorbing colorant, is selectively applied on at least a portion of the build material. A white ink, including a white colorant that is opaque in visible wavelengths and is transparent to infrared wavelengths, is selectively applied on the black ink. A colored ink, including a colorant having a color other than black or white, is selectively applied on the white ink. The build material and the applied inks are then exposed to infrared radiation. The black ink at least partially fuses the portion of the build material in contact therewith. At least some of the white colorant and the colorant are embedded in the at least partially fused portion at a surface thereof.

The white ink can include an aqueous ink vehicle, from 5 wt % to 50 wt % of a white metal oxide pigment, and from 0.02 wt % to 2 wt % of an anionic low molecular weight polymer. The white metal oxide pigment can have an average particulate size from 100 nm to 2,000 nm, and can be dispersed by a non-ionic or predominantly non-ionic dispersant having an acid number not higher than 100 mg KOH/g based on dry polymer weight. The anionic low molecular weight polymer can have a weight average molecular weight of 3,000 Mw to 50,000 Mw and an acid number higher than 100 mg KOH/g based on dry polymer weight.
