Abstract
An ink sorptive coating for ink jet recording media, and ink jet recording media that contain the same, wherein the ink jet recording medium contains a substrate having an ink sorptive layer coated thereon. The ink sorptive coating layer contains (1) a polymer or copolymer that comprises a polyalkyl oxazoline monomer unit or a polyphenyl oxazoline monomer unit, or a copolymer that comprises a polyalkyl oxazoline monomer unit and a polyphenyl oxazoline monomer unit, and (2) a hydrophilic, water-insoluble polymer or copolymer which preferably contains hydroxyl groups. The ink sorptive coating provides the ink jet media with improved image quality, dry time and a low degree of curl.
