Patent ID: 8398233

Claim:
An inkjet recording medium, comprising: a substrate; and an ink receiving layer disposed on a surface of the substrate, the ink receiving layer including cationically-modified fumed silica having nanoparticles of any of alumina or silica mixed therein, the cationically-modified fumed silica being present in an amount ranging from about 60 wt % to about 90 wt % of a total amount of pigment present in the ink receiving layer, the alumina nanoparticles having an individual particle size ranging from about 15 nm to about 50 nm and being present in an amount ranging from about 10 wt % to about 40 wt % of the total amount of pigment present in the ink receiving layer, and the silica nanoparticles having an individual particle size ranging from about 5 nm to about 45 nm and being present in an amount ranging from about 10 wt % to about 30 wt % of the total amount of pigment present in the ink receiving layer; wherein the ink receiving layer has a coating density that is equal to or greater than about 0.7 g/cc.
