Patent ID: 7150522

Claim:
An improved process for producing an ink-jet recording media by applying a sealable topcoat to an ink-receptive coating on a substrate comprising: (a) applying a porous ink-receptive coating to a surface of said substrate, said porous ink-receptive coating comprising a plurality of pores; (b) applying an anionic porous topcoat on said porous ink-receptive coating, said porous topcoat consisting essentially of polymer particles having a T g within a range of 60° to 100° C. and a size less than 250 nanometers and, optionally, at least one pigment and at least one binder; (c) drying said topcoat at a temperature below said T g ; (d) printing an image on said topcoat of said ink-jet recording media with a dye-based ink, and (e) applying heat to said topcoat above the T g of the polymer and within said T g range until said topcoat is fused.
