Abstract: An ink composition for continuous deflected ink jet printing, liquid at ambient temperature is disclosed. One aspect is an ink composition comprising: a solvent including organic solvent compound(s), and optionally water, the solvent representing at least 20 % by weight of the total weight of the ink. Furthermore, there is at least one compound imparting conductivity to the ink composition, chosen from among the ionic liquids, the 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. Lastly, the ink composition includes 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.

Abstract: Thermochromic ink composition for ink jet printing, liquid at room temperature, comprising: a) a solvent; b) a binder; c) a heat resistant, and water or steam resistant pigment; d) a heat sensitive, and water or steam sensitive, dye; wherein the pigment and the dye are selected to be complementary in the colour spectrum, and wherein said dye is capable of undergoing decomposition upon exposure to both heat and water or steam so that the colour of the ink composition or of a marking printed using said ink composition changes to the colour of the pigment upon exposure to both heat and water or steam. Method for marking a substrate by spraying said ink composition onto this substrate, and substrate provided with a marking obtained by drying and/or absorption of said ink composition. Method of indicating sterilization or pasteurization or autoclaving of a substrate using said ink.
