Title
(EN) NON-NEWTONIAN INKJET INKS
(FR) ENCRES À JET D'ENCRE NON NEWTONIENNES
Abstract
(EN) The present disclosure provides non-Newtonian inkjet inks and related methods. In one example, a non-Newtonian inkjet ink can comprise a low molecular weight organic gelator in an amount ranging from 0.1% to 10% by weight based on the total weight of the non-Newtonian inkjet ink; a salt in an amount of 0.05% to 20% by weight based on the total weight of the non-Newtonian inkjet ink; and an organic solvent. Additionally, the low molecular weight organic gelator and the salt can form a structured network and the inkjet ink can have a viscosity ranging from 100 cps to 10,000 cps at a temperature of 25 °C and a viscosity ranging from 1 cps to 10 cps at a temperature of 50 °C.
(FR) La présente invention concerne des encres à jet d'encre non newtoniennes, et des procédés associés. Dans un exemple, une encre à jet d'encre non newtonienne peut comprendre: un gélifiant organique de faible poids moléculaire dans une quantité allant de 0,1 % à 10 % en poids par rapport au poids total de l'encre à jet d'encre non newtonienne; un sel dans une quantité de 0,05 % à 20 % en poids par rapport au poids total de l'encre à jet d'encre non newtonienne; et un solvant organique. En outre, le gélifiant organique de faible poids moléculaire et le sel peuvent former un réseau structuré et l'encre à jet d'encre peut avoir une viscosité allant de 100 cps à 10.000 cps à une température de 25 °C, et une viscosité allant de 1 cps à 10 cps à une température de 50° C.
