Title
(EN) INK COMPOSITION
(FR) COMPOSITION D'ENCRE
Abstract
(EN)
The present invention relates to an ink composition suitable for being ejected from an inkjet marking device at an operating temperature. The ink composition comprises a water-dispersible resin and has a dynamic surface tension of below 35 mN/m and a static surface tension of above 21 mN/m both determined at the operating temperature. The ink composition may comprise a mixture of water-soluble organic solvents having a difference in the relative dielectric constant of more than 5, preferably between 10 and 50. The ink composition may comprise a polymeric cosolvent, in particular a polyethylene glycol or polyethylene glycol (di)methyl ether. The ink composition may comprise a mixture of surfactants comprising at least one surfactant of a first type selected from the group consisting of acetylene glycols and ethoxylated acetylene glycols and at least one surfactant of a second type selected from the group consisting of silicone surfactants and fluorochemical surfactants.

La présente invention concerne une composition d'encre appropriée pour être éjectée d'un dispositif de marquage à jet d'encre à une température de fonctionnement. La composition d'encre comprend une résine dispersible dans l'eau et présente une tension de surface dynamique inférieure à 35 mN/m et une tension de surface statique supérieure à 21 mN/m, toutes deux déterminées à la température de fonctionnement. La composition d'encre peut comprendre un mélange de solvants organiques solubles dans l'eau présentant une différence en termes de permittivité relative supérieure à 5, de préférence entre 10 et 50. La composition d'encre peut comprendre un cosolvant polymère, en particulier un éther de polyéthylène glycol ou de polyéthylène glycol (di)méthyle. La composition d'encre peut comprendre un mélange de tensioactifs renfermant au moins un tensioactif d'un premier type choisi dans le groupe constitué de glycols d'acétylène et de glycols d'acétylène éthoxylés et au moins un tensioactif d'un second type choisi dans le groupe constitué de tensioactifs de silicone et de tensioactifs fluorochimiques.
