(FR) COMPOSITION D’ENCRE POUR JET D’ENCRE
Abstract:
(EN) In one aspect the present disclosure relates to an aqueous inkjet ink composition comprising a yellow azo pigment, a pigment synergist, a polymeric dispersant, 5 to 20 wt % of a latex polymer, 5 to 40 wt% of an organic co-solvent that has a boiling point of a boiling point in the range of about 170 °C to about 285 °C, and water. The pigment synergist comprises a pigment of the formula (I): where each of R1 to R10 is each independently selected from H, carboxylate, and/or a sulphonate group.
(FR) Selon un aspect, la présente invention concerne une composition d'encre aqueuse pour jet d'encre comprenant un pigment azoïque jaune, un synergiste de pigment, un dispersant polymère, 5 à 20 % en poids d'un polymère de latex, 5 à 40 % en poids d'un co-solvant organique qui a un point d'ébullition dans la plage d'environ 170 °C à environ 285 °C, et de l'eau. Le synergiste de pigment comprend un pigment de la formule (I), chaque constituant de R1 à R10 étant choisi indépendamment parmi un H, un carboxylate et/ou un groupe sulfonate.
