Abstract
Re-dispersible pigmented printing ink compositions, preferably for the continuous ink jet printing process are obtained by the addition of a flocculating agent to the pigment dispersion in the printing liquid. The compositions do not form hard sediments and are easy to re-disperse on stopping and resuming the printing operations. Suitable flocculating agents bind the pigment particles in the sediment into three-dimensional 'airy' structures, which are easy to break up. The ink compositions of the invention are furthermore characterized by a good printability in the dispersed state.
