INK-JET OVERCOATS INCLUDING LATEX POLYMERS AND INORGANIC NANO PARTICLES

摘要

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.
