Abstract: An aqueous ink composition including water; an optional co-solvent; a sulfonated polyester, wherein the sulfonated polyester has a degree of sulfonation of at least about 3.5 mol percent; and an isoprene rubber. A process of digital offset printing including applying an ink composition onto a re-imageable imaging member surface at an ink take up temperature, the re-imageable imaging member having dampening fluid disposed thereon; forming an ink image; transferring the ink image from the re-imageable surface of the imaging member to a printable substrate at an ink transfer temperature; wherein the ink composition comprises water; an optional co-solvent; a sulfonated polyester having a degree of sulfonation of at least about 3.5 mol percent; and an isoprene rubber. A process including combining a sulfonated polyester resin, having a degree of sulfonation of at least about 3.5 mol percent, water, an optional co-solvent, and an isoprene rubber to form an aqueous ink composition, wherein the ink composition is substantially colorless.

Abstract: Tintenzusammensetzung, die Folgendes enthält: eine Feuchthaltemittelmischung, die ein erstes Feuchthaltemittel und ein zweites Feuchthaltemittel umfasst; wobei das erste Feuchthaltemittel einen Gefrierpunkt aufweist; wobei das zweite Feuchthaltemittel den Gefrierpunkt des ersten Feuchthaltemittels unterdrückt, um der Tintenzusammensetzung die Eigenschaft zu verleihen, bei einer gewünschten Temperatur gelagert werden zu können, ohne zu erstarren; Wasser; ein optionales Co-Lösungsmittel; ein optionales Farbmittel; und einen sulfonierten Polyester. Ein Vorgang des digitalen Offsetdrucks unter Verwendung der Tintenzusammensetzung.

Abstract: An ink composition including a humectant blend comprising a first humectant and a second humectant; wherein the first humectant has a freezing point; wherein the second humectant suppresses the freezing point of the first humectant such as to impart to the ink composition the characteristic of being able to be stored at a desired temperature without solidifying; water; an optional co-solvent; an optional colorant; and a sulfonated polyester. A process of digital offset printing using the ink composition.
