Patent ID: 8449669

Claim:
A composition for cast-coating on ink-jet media using a cast-coating drum, comprising: a liquid vehicle; a plurality of silica particulates suspended in the liquid vehicle in an amount of about 1 wt % to about 35 wt %, said silica particulates having a particle size less than about 150 nm; and from 0.5 wt % to 10 wt % of internal release agent, wherein the composition is substantially free of a polymeric binder, and wherein the composition, when cast-coated on a porous particulate-coated ink-receiving media to a coat weight of less than 2 gsm, produces a gloss increase of at least 2 gloss units at 20 degrees over the gloss of the porous particulate-coated ink-receiving media, and wherein the composition has a surface energy greater than the surface energy of the cast-coating drum.
