Problems solved by technology

[0053] In general, it is well known that at low temperatures the solubility of salts decreases and the risk of precipitation or crystallization increases
[0054] According to the above content, there is almost no one kind of salt that can meet the above standards and requirements at the same time

Embodiment

[0204] The following ink compositions according to the invention were prepared by mixing the products given in Table I below in the proportions indicated. The viscosity and conductivity of the inks obtained are also given below.

[0205] Viscosity was measured using a low shear 30 coaxial cylinder viscometer from Contraves (Switzerland) at 20 °C and conductivity at room temperature, typically 20 °C.

[0206] Table I

[0207]

[0208] The ink compositions of the present invention prepared according to Examples 1 to 4 and those of Comparative Examples 1 and 2 were filtered on a filter having a pore size of 1 μm to give an ink capable of inkjet by jetting.

[0209] exist The inks thus prepared were tested on a 9040 model continuous deflection inkjet printing printer.

[0210] The marks, prints obtained using the inks in Examples 1 to 4 and Comparative Examples 1 and 2 were all of high quality and their resistance to friction of water on glass was excellent.

Abstract

An ink composition for continuous deflected ink jet printing, liquid at ambient temperature, comprising: a) a solvent comprising, preferably consisting of, one or organic solvent compound(s), and optionally water, the said solvent representing at least 20 % by weight of the total weight of the ink; b) at least one compound imparting conductivity to the ink composition, chosen from among the ionic liquids, the said 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; and the ink composition comprising 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. A process for marking substrates using said ink composition. A substrate provided with a marking obtained by drying and / or absorption of said ink composition.

Description

technical field [0001] The present invention relates to ink compositions for marking all types of supports, substrates and objects, the properties of which are particularly suitable for liquid jet printing or marking, and especially for the marking of a very wide variety of supports, substrates, and objects Continuously deflected inkjet marks whether they are porous or non-porous. Background technique [0002] Inkjet printing is a well-known technology that allows to print, mark or decorate all types of objects at high speed with information that can change according to requirements, such as barcodes, sales deadlines, etc., and without bringing these objects into contact with printing devices, And even on non-planar supports. [0003] Inkjet printing systems can be divided into two main types: "drop-on-demand" (DOD) or "continuous inkjet (CJ)". [0004] We are more interested in the latter process, and more specifically in continuous deflection inkjet technology. [0005]...
