Title (EN) INK COMPOSITIONS
(FR) COMPOSITIONS D'ENCRE
Abstract:
(EN) The present disclosure is drawn to an ink composition including an aqueous liquid vehicle, from 2 wt% to 7 wt% self-dispersed pigment dispersed in the aqueous liquid vehicle, and from 0.5 wt% to 5 wt% acidic polymeric binder particles having an acid number from 30 to 200 and a particle size from 1 nm to 100 nm dispersed in the aqueous liquid vehicle. The ink composition can also include from 0.1 wt% to 0.75 wt% monovalent salt solubilized in the aqueous liquid vehicle. The self-dispersed pigment to monovalent salt weight ratio in the ink composition can be from 3:1 to 50:1, for example.
(FR) La présente invention concerne une composition d'encre comprenant un véhicule liquide aqueux, de 2 % en poids à 7 % en poids de pigment à dispersion spontanée dispersé dans le véhicule liquide aqueux, et de 0,5 % en poids à 5 % en poids de particules de liant polymère acide ayant un indice d'acide de 30 à 200 et une taille de particule de 1 nm à 100 nm dispersées dans le véhicule liquide aqueux. La composition d'encre peut aussi comprendre de 0,1 % en poids à 0,75 % en poids d'un sel monovalent solubilisé dans le véhicule liquide aqueux. Le rapport pondéral pigment à dispersion spontanée sur sel monovalent dans la composition d'encre peut, par exemple, être compris entre 3:1 et 50:1.
