Title (EN) POLYMERS FOR INKJET INK COMPOSITIONS
(FR) POLYMÈRES POUR COMPOSITIONS D'ENCRE À JET D'ENCRE
Abstract:
(EN) Disclosed herein are polymers, which can be incorporated in pigment dispersions and inkjet ink compositions, comprising first monomers selected from ethylenically unsaturated hydrophobic monomers, and second monomers selected from maleic anhydride, maleic acid, and salts, esters, imides, and amides thereof. The polymers can have a portion of the second monomers functionalized with at least one organic group having a calcium index value greater than or equal to a calcium index value of phenylphosphonic acid. Additionally and/or alternatively, the at least one polymer can be crosslinked via the second monomers. Dispersions and inkjet ink compositions comprising such polymers can also further comprise at least one pigment and a liquid vehicle. Also disclosed are methods of making such polymers.
(FR) L'invention concerne des polymères, qui peuvent être incorporés dans des dispersions de pigment et des compositions d'encre à jet d'encre, comprenant des premiers monomères choisis parmi des monomères hydrophobes à insaturation éthylénique, et des seconds monomères choisis parmi l'anhydride maléique, l'acide maléique, et leurs sels, esters, imides et amides. Une partie des seconds monomères desdits polymères peuvent être fonctionnalisés avec au moins un groupe organique ayant une valeur d'indice de calcium supérieure ou égale à la valeur d'indice de calcium de l'acide phénylphosphonique. En outre et/ou en variante, les polymères peuvent être réticulés par l'intermédiaire des seconds monomères. Les dispersions et compositions d'encre à jet d'encre comprenant ces polymères peuvent en outre également comprendre au moins un pigment et un véhicule liquide. Des procédés de production desdits polymères sont en outre décrits.
