Sealable topcoat for porous media

摘要

A process is provided that allows the production of an ink-jet recording media (10) by applying a sealable topcoat (18) to an ink-receptive coating (14) on a substrate (12). A porous ink-receptive coating (14) comprising a plurality of pores is applied to a surface of the substrate (12). An anionic porous topcoat (18) comprising polymer particles (16) having a Tg in the range of 60 DEG to 100 DEG C and a size less than 250 nanometers is applied on the porous ink-receptive coating (14). The topcoat (18) is then dried at an elevated temperature and an image is printed on the topcoat (18) of the ink-jet recording media (10) using a conventional ink-jet printer. The topcoat (18) is then heated until it becomes fused by using a heating device. The media (10) formed provides the advantages of improved air fade resistance, good image quality and high gloss.
