Abstract:
Liquid composition, such as an ink composition, liquid at room temperature, the liquid composition being a liquid composition specifically for printing with a binary deflected continuous jet printing technique wherein the liquid composition forms upon printing drops which are not charged by an electric field, which each have a zero electric charge, which each form a dipole under the effect of an electric field, and then are then deflected by the electric field, characterised in that the liquid composition comprises a solvent comprising one or more organic solvent compound(s) and optionally water, the solvent having globally a dielectric constant less than 15; a binder; one or more dyes and/or pigments; and in that the liquid composition has an electrical conductivity at 20° C. less than or equal to 200 μS/cm, preferably less than or equal to 150 μS/cm, still preferably less than or equal to 100 μS/cm.
