The present invention features an inkjet recording medium suitable for recording images with dye and pigmented inks, comprising a substrate coated with at least two layers comprising: n (a) a first ink-receptive layer comprising a polymeric binder and a cross-linker and optionally containing a plasticizer coated over the substrate; and n (b) a second layer comprising of 45 to 98% of polymeric binders where at least one binder is selected from group of polymers consisting of: n (i) at least one copolymer of hydroxyethylmethacrylate, a polymer and copolymer of vinylpyrrolidone, and n (ii) a fully or partially hydrolyzed polyvinyl alcohol and its derivatives, and combination thereof, n wherein the second layer optionally further contains at least one nitrogeneous polymer, at least one non-polymeric nitrogenous compound, or a mixture thereof, wherein the nitrogenous polymer or nitrogenous compound preferably has a pKa higher than 8, and more preferably higher than 9, n wherein said first layer is located between said second layer and the substrate in said recording medium. The paper 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. Images printed on this paper substrate are bleed-resistant, water-resistant (e.g., water-fast), and/or are characterized by an enhanced chroma and hue. |
