Abstract
The present invention is drawn to a composition for cast-coating on ink-jet media. The composition includes a liquid vehicle, silica particulates, and an internal release agent. The composition is substantially free of polymeric binder and can improve the glossiness of a porous particulate-coated ink-receiving media by at least 2 gloss units at 20 degrees. The silica particulates can be suspended in the liquid vehicle at about 1-35 wt %, and can have a particle size of less than about 150 nm. The internal release agent can be present at about 0.5-10 wt %.
