Abstract: An inkjet ink includes pigment, dispersing agent, fixing agent, binder and water. The binder is selected from polyurethanes of a low acid value, the dispersing agent has a low acid value, and the fixing agent is a multivalent calcium salt used in a low concentration. The inkjet ink is easy to apply by using commercial inkjet printing presses, has high storage stability, adheres to surfaces that do not absorb water, exhibits high resistance to wiping and is very advantageously capable of being overprinted by other water-based inkjet inks. A printing process is also provided.

Abstract: The invention is directed to a printing process in which a substrate to be printed is disposed opposite an ink carrier having a liquid ink layer and the liquid ink layer is irradiated regionally, wherein the liquid ink layer comprises a liquid and carbon containing particles X dispersed in the liquid, where said carbon containing particles X are present as carbon nanotube particles, graphite particles and/or structural analogue particles of graphite selected from the group consisting of graphene particles, graphene oxide particles, graphite oxide particles, fullerene particles and particles of graphite intercalation compounds.
