Abstract
A liquid composition, including a solvent, for printing with a binary deflected continuous jet printing technique, wherein upon printing the liquid composition form drops that are each: not charged by an electric field, have a zero electric charge, form a dipole under the effect of an electric field, and are then deflected by the electric field. The liquid composition has all the following characteristics: a conductivity at 20° C. from 5 to 500 μS/cm, still preferably a conductivity at 20° C. from 5 to 500 μS/cm, the value of 500 μS/cm being excluded, better a conductivity at 20° C. from 5 to 400 μS/cm, still better a conductivity at 20° C. from 30 to 400 μS/cm, for example from 30 to 200 μS/cm; a dynamic viscosity at 20° C. from 1 to 25 cPs, preferably from 6 to 25 cPs; and a density from 0.8 to 2.5 g/cm3, preferably from 1.2 to 2.5 g/cm3.
