ABSTRACT:
A process is provided that allows the production of an ink-jet recording media by applying a sealable topcoat to an ink-receptive coating on a substrate. A porous ink-receptive coating including a plurality of pores is applied to a surface of the substrate. An anionic porous topcoat consisting essentially of polymer particles having a Tgin the range of 60° to 100° C. and a size less than 250 nanometers is applied on the porous ink-receptive coating. The topcoat is then dried at an elevated temperature and an image is printed on the topcoat of the ink-jet recording media using a conventional ink-jet printer. The topcoat is then heated until it becomes fused by using a heating device. The media formed provides the advantages of improved air fade resistance, good image quality and high gloss.
