An ink composition for continuous deflected ink jet printing, liquid at ambient temperature, comprises: a) a solvent comprising, preferably consisting of, one or more organic solvent compound(s), and optionally water, the said solvent representing at least 20 % by weight of the total weight of the ink; b) at least one compound imparting conductivity to the ink composition, chosen from among the ionic liquids, the said compound representing 0.2 % by weight to 4 % by weight of the total weight of the ink composition, preferably 0.5 to 3 % by weight of the total weight of the ink composition; and the ink composition comprising less than 10 % by weight, preferably less than 5 % by weight, more preferably less than 1 % by weight, and most preferably 0 % by weight of water relative to the total weight of the ink composition. A process for marking substrates using said ink composition. A substrate provided with a marking is obtained by drying and/or absorption of said ink composition. |
