Abstract: The described invention is an unique universal ink jet media. The invention incorporates a unique barrier layer based upon UV or EB curable chemistry which replaces common polyethylene extruded bases. The invention also incorporates multiple ink receptive layers. The first layer is based upon gelatin and/or polyvinyl alcohol (PVOH) chemistries and gives the invention excellent ink drytime. Poor drytime is a common problem which leads to smudging and print defects, especially as ink jet printer speeds increase as technology improves. The high ink absorbency of the invention also makes this media well suited for wide format ink jet printers. The next ink receptive layer(s) are based upon pigmented, cellulose chemistry which reduces the tack of the sheet and gives the sheet good waterfastness. This is important for the end use in that the sheet may be frequently handled and exposed to dampness.

Abstract: This patent describes an inkjet printable recording media that dries quickly to produce a waterfast, water-resistant and smudge-resistant print. The media is especially well-suited for the growing field of digital photography where a durable photo-like print is desired, and for high-speed commercial inkjet printing. The invention provides novel coatings, coated media, and methods of use. In particular, the coatings comprise a porous, water-absorbent base coating, a water-resistant ink-receptive coating comprised of nanoparticle-sized pigments, and, optionally, a glossy top coating. The novel coated media comprises an inkjet printable substrate having multiple coating layers, and provides high quality, waterfast images. When used on an inkjet printer, the coated media permits the ink to dry almost instantly to produce a waterfast, high gloss image.
