Abstract
The present invention is drawn to a media sheet for ink-jet printing and can comprise a media substrate and a coating composition applied to the media substrate to form an ink-receiving layer. The ink-receiving layer can include semi-metal oxide or metal oxide particulates, at least 5 wt % of a water soluble coating formulation additive, and a binder. The media sheet can also have a wash conductivity less than about 80 microsiemens/cm, said wash conductivity determined by measuring the conductivity of a 50 mL bath of deionized water after placing a 100 cm2 sample of the media sheet in the deionized water for 45 seconds at room temperature under agitation.
