Inkjet recording medium suitable for recording images with dye and pigmented inks, comprising a substrate coated with a first ink-receptive layer of a polymeric binder and a cross-linker and a second layer of 45-98% of polymeric binders where at least one binder is a copolymer of hydroxyethylmethacrylate, a polymer and copolymer of vinylpyrrolidone, a fully or partially hydrolyzed polyvinyl alcohol and its derivatives, or combination thereof. The second layer optionally further contains at least one nitrogeneous polymer or non-polymeric nitrogeneous compound, or a mixture thereof, having a pKa of at least 8 and preferably greater than 9. The substrate provides high quality printed images when printed with an ink containing a reactive dye having ionizable and/or nucleophilic groups capable of reacting with the coating agent in one or more of the two layers. Printed images are bleed-resistant, water-resistant, and/or are characterized by an enhanced chroma and hue. |
