Beschreibung
Zusammenfassung:	The present disclosure provides novel aqueous ink-jet inks containing an aqueous vehicle, a pigment and a random polyurethane copolymer as a binder. The random polyurethane copolymer contains short hard segments without any ionic group. Also disclosed is the use of these dispersions in an ink-jet ink. La présente invention concerne de nouvelles encres aqueuses pour jet d'encre contenant un véhicule aqueux, un pigment et un copolymère de polyuréthane aléatoire comme liant. Le copolymère de polyuréthane aléatoire contient des segments durs courts sans aucun groupe ionique. L'invention concerne également l'utilisation de ces dispersions dans une impression pour jet d'encre.
