Title (EN) INK-JET OVERCOATS INCLUDING LATEX POLYMERS AND INORGANIC NANO PARTICLES
(FR) COUCHES DE FINITION POUR IMPRESSION JET D'ENCRE COMPRENANT DES POLYMÈRES DE LATEX ET DES NANOPARTICULES INORGANIQUES
Abstract:
(EN) The present disclosure is drawn to a nanoparticle containing overcoat composition for use in ink-jet printing. The composition can include a liquid vehicle and a composite latex particulate. The composite latex particulate can include inorganic nanoparticles at least partially encapsulated by a polymer. The inorganic nanoparticles can be silica, titania, alumina, zinc oxide, silicates, oxides of indium and tin, and combinations thereof. The inorganic nanoparticles can comprise from about 1 wt% to about 20 wt% of the composite latex particulate. The overcoat composition can be used to improve the properties of ink-jetted images.
(FR) La présente invention concerne une composition pour couche de finition contenant des nanoparticules et utilisable en impression jet d'encre. Ladite composition peut comprendre un support liquide et un matériau particulaire composite à base de latex. Ledit matériau particulaire composite à base de latex peut comprendre des nanoparticules inorganiques au moins partiellement encapsulées dans un polymère. Lesdites nanoparticules inorganiques peuvent être constituées de silice, de titane, d'alumine, d'oxyde de zinc, de silicates, d'oxydes d'indium et d'étain, ainsi que de combinaisons de ceux-ci. Lesdites nanoparticules inorganiques peuvent comprendre d'environ 1 à environ 20 % en poids de matériau particulaire composite à base de latex. Ladite composition pour couche de finition peut être utilisée pour améliorer les propriétés des images obtenues par impression jet d'encre.
