Zusammenfassung:An ink-jet ink is disclosed which comprises polymer-dispersed pigment particles in a liquid vehicle, wherein the polymer has an acid number of at least about 175 and comprises polymer molecules having anionic groups and hydrogen bond-forming groups. The anionic groups and the hydrogen bond-forming groups are configured on each of the polymer molecules to permit association of the anionic groups with cationic groups on a print medium, and to also permit the hydrogen bond-forming groups on neighboring polymer molecules to interact pair wise with each other, as the liquid vehicle dries and/or is absorbed into the medium.
