Beschreibung
Zusammenfassung:	An inkjet overcoat composition includes an aqueous vehicle. The inkjet overcoat composition also includes modified silica nanoparticles dispersed in the aqueous vehicle and a sugar alcohol dissolved or dispersed in the aqueous vehicle. Each modified silica nanoparticle includes a silica core and a hydrotropic silane coupling agent attached to the silica core. La présente invention concerne une composition de couche de finition pour jet d'encre qui comprend un véhicule aqueux. La composition de couche de finition pour jet d'encre comprend également des nanoparticules de silice modifiées dispersées dans le véhicule aqueux et un alcool de sucre dissous ou dispersé dans le véhicule aqueux. Chaque nanoparticule de silice modifiée comprend un cœur de silice et un agent de couplage silane hydrotropique fixé au cœur de silice.
