Beschreibung
Zusammenfassung:	A pigment ink composition for printing of a textile substrate is liquid at room temperature and includes a solvent. A binary deflected continuous jet printing technique is used. The ink composition forms, during printing, drops that are not charged by an electric field, each have a zero electric charge, and each form a dipole under the effect of an electric field. The drops are deflected by the electric field. The ink composition includes: an aqueous solvent including at least 50% by volume of water based on the total volume of the solvent; at least 13% by weight based on the total weight of the ink composition, of one or several dispersion(s) of binding polymer(s); and one or several dispersion(s) of pigment(s); wherein the weight ratio of the dispersion(s) is greater than 2; and the ink composition has a dynamic viscosity at 20° C. of more than 16 cPs.
