Abstract
The present invention is directed to an ink jet recording medium. The ink jet recording medium has an ink absorbent layer provided upon a substrate, with a humidity barrier layer provided upon the ink absorbent layer. The ink absorbent layer comprises a blend of poly(2-ethyl-2-oxazoline), poly(vinyl pyrollidone), and a hydrophobic polymer, and the humidity barrier layer comprises a blend of polyethylene oxide and boehmite alumina. The ink jet recording medium is fast drying over different relative humidity conditions, making it particularly suitable for high speed printing applications.
