Abstract
Aqueous, low viscosity, stable printing ink compositions suitable for drop-on-demand ink jet printing contain specific selected amounts of a solid pigment preparation, a water-soluble organic solvent, a humectant and water so that the compositions resist clogging ink jet nozzles and give prints of excellent image resolution which are resistant to water and migration.
