    Abstract: The present invention relates to a method of printing an image on a fibrous substrate by inkjet printing, wherein the method comprises applying a water-based ink composition onto the substrate, wherein the ink composition comprises a carboxylic or sulfonic acid functional co-polymer having an acid number of ≥ 225 mg KOH/g, a pigment, water and at least one organic co-solvent. The present invention also relates to use of said water- based ink composition for printing an image on a fibrous substrate by inkjet printing.

    Abstract: A thermal inkjet dye sublimation ink consists of a disperse dye colorant dispersion, a co-solvent system, an additive, and a balance of water. The colorant dispersion is present in an amount ranging from about 1 wt% actives to about 7 wt% actives. The co-solvent system is present in a total amount ranging from about 12 wt% to about 25 wt%. The co-solvent system consists of glycerol present in an amount ranging from about 9 wt% to about 16 wt%, ethoxylated glycerol present in an amount ranging from 0 wt% to about 5 wt%, and a water soluble or water miscible organic solvent present in an amount ranging from 0 wt% to about 7 wt%. The additive is selected from the group consisting of a surfactant, a chelating agent, a buffer, a biocide, and combinations thereof.

    Abstract: The present disclosure is drawn inkjet inks, which can include an aqueous ink vehicle and a pigment particle having a block copolymer attached to a surface of the pigment particle. The block copolymer can be linked to the surface through a nitrogen atom-containing coupling group bonded to the surface through the nitrogen atom. The block copolymer can include a steric stabilizing block formed by polymerizing a monomer having a sterically bulky group, and an ionic stabilizing block formed by polymerizing a monomer having an acidic group or a basic group.
