ABSTRACT:
An ink-jet recording media is provided with a sealable coating that is applied to a non-permeable substrate to improve fade resistance, dry time and water resistance. The ink-jet recording media comprises: (a) a non-permeable substrate; (b) a porous basecoat disposed on a surface of the non-permeable substrate, the basecoat comprising at least one pigment, at least one binder, and, optionally, at least one mordant, and adapted to receive a colorant from an ink comprising at least one colorant and a liquid vehicle containing at least one polar solvent; and (c) a porous topcoat. Either (1) the porous basecoat further comprises a solvent-swellable polymer, adapted to swell when contacted by at least one polar solvent of the liquid vehicle, and the porous topcoat is either optional or comprises at least one pigment and at least one binder, or (2) the porous topcoat comprises the solvent-swellable polymer and at least one binder.
