Patent ID: 7866811

Claim:
A print medium, comprising: a substrate; a porous ink-receiving layer disposed on the substrate, the porous ink-receiving layer including at least one water-soluble polymer and greater than about 80% content of inorganic particles, the at least one water-soluble polymer selected from the group consisting of polyvinyl alcohol, cationic polyvinylalcohol, acetoacetylated polyvinylalcohol, silylated polyvinylalcohol, carboxylated polyvinylalcohol, polyvinylpyrrolidone, copolymer of polyvinylacetate and polyvinylpyrrolidone, copolymer of polyvinylalcohol and polyvinylpyrrolidone, cationic polyvinylpyrrolidone, starch or derivatives thereof, gelatin or derivatives thereof, cellulose or derivatives thereof, maleic anhydride polymers or copolymers thereof, acrylic ester copolymers, polyacrylamide, casein, water- or ammonia-soluble polyacrylates, polymethacrylates and copolymers thereof, and combinations thereof; and a porous surface layer disposed on the porous ink-receiving layer, wherein the porous surface layer includes polymer particles and a non-ionic stabilizing surfactant, the polymer particles having an average particle size ranging from about 100 nanometers to 300 nanometers.
