LIQUID COMPOSITION, ESPECIALLY INK COMPOSITION, FOR PRINTING WITH A BINARY DEFLECTED CONTINUOUS JET, WITH NON-CHARGED DROPS, USE OF SAID COMPOSITION, MARKING METHOD AND MARKED SUBSTRATE

Liquid composition, such as an ink composition, liquid at room temperature, said liquid composition being a liquid composition specifically for printing with a binary deflected continuous jet printing technique wherein said 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 said electric field, characterised in that said liquid composition comprises a solvent comprising one or more organic solvent compound(s) and optionally water, said solvent having globally a dielectric constant less than 15; a binder; one or more dyes and/or pigments; and in that said 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. Use of this liquid composition in a printer or printing head implementing said printing technique. Method for treating and/or marking a substrate by projection of said liquid composition on this substrate by said printing technique. Substrate, provided with a marking or treatment obtained by drying and/or absorption of said liquid composition.
