    摘要： Disclosed herein are inkjet ink compositions comprising: at least one pigment and at least one polyurethane comprising: at least one polypropylene glycol, and at least one diisocyanate. The at least one polyurethane contains at least 70 wt % polypropylene glycol relative to the at least one polyurethane and has a weight average molecular weight (Mw) of no more than 80,000.

    摘要： Disclosed herein are polymers, which can be incorporated in pigment dispersions and inkjet ink compositions, comprising first monomers selected from ethylenically unsaturated hydrophobic monomers, and second monomers selected from maleic anhydride, maleic acid, and salts, esters, imides, and amides thereof. The polymers can have a portion of the second monomers functionalized with at least one organic group having a calcium index value greater than or equal to a calcium index value of phenylphosphonic acid. Additionally and/or alternatively, the at least one polymer can be crosslinked via the second monomers. Dispersions and inkjet ink compositions comprising such polymers can also further comprise at least one pigment and a liquid vehicle. Also disclosed are methods of making such polymers.
