Abstract
A printing medium suitable for inkjet printing comprises a substrate having at least two water-absorptive coatings applied sequentially. Each of the two water-absorptive coatings comprises hydrophilic organic polymer and small discrete nonfilm-forming particles. The hydrophilic organic polymer of the interior water-absorptive coating adjacent the exterior water-absorptive coating contains a greater quantity of nitrogen-containing substance than the hydrophilic organic polymer of the exterior water-absorptive coating. 'Nitrogen-containing substance' is defined as being independently selected from the group consisting of quaternary ammonium mer units, poly(N-vinylpyrrolidinone), copolymer of N-vinylpyrrolidinone and .alpha.-(meth)acrylyloxy-.omega.-(hydroxy, methoxy, or ethoxy)-poly(ethylene oxide), and two or more thereof.
