Full range ink jet recording medium

The invention relates to an ink jet recording medium having two coating layers on a base substrate. The surface coating layer of the medium primarily comprises inorganic particulates and the underlayer coating layer of the medium primarily comprises polymeric materials. More particularly, this invention relates to an ink jet recording medium that performs well within a full environment range.

The present invention is directed to an anti-fogging coating that can be used for anti-fog applications. The coating is transparent, and comprises a hydroxyl group containing polymer, an aluminum containing crosslinker, and a surface active agent containing hydroxyl and/or siloxane groups. Additionally, the coatings possess a T.sub.fog of greater than about 30 minutes and a haze of less than about 5%, and can advantageously be used to provide to glass or plastic substrates an anti-fogging surface.

Transparent anti-fog coating

The present invention is directed to an ink-receiving sheet having anti-blocking properties, containing (A) a polymer substrate; (B) an ink-receptive coating disposed on at least one layer which having a water-soluble component; and (C) particulates dispersed in the ink-receptive coating, having an average particle size of from 15 um to about 50 um, a particle size span is equal to or smaller than 1.0, and a refractive index of from about 1.2 to about 2.4. The present invention is also directed to the ink receptive coating per se, and to methods of ink jet printing using the above ink-receiving sheet.

Anti-blocking clear ink receiving sheet

The present invention is directed to a polymer matrix coating used for ink jet recording media. The polymer matrix coating has a glass transition temperature that is greater than or equal to about 120.degree. C. and less than or equal to about 300.degree. C., an integrity value of greater than or equal to about -20% and a swellability of greater than or equal to about 50%. The coating avoids the problem of pigment ink cracking that can occur in conventional ink jet recording media.

Polymer matrix coating for ink jet media

Film mediums useful in ink jet printing which films comprises a transparent, translucent or opaque substrate, having on at least one side thereof a water-insoluble, water-absorptive and ink-receptive matrix, said matrix comprised of a hydrogel complex and a polymeric high molecular weight quaternary ammonium salt.

Archivable ink jet recording media

A film medium useful in ink jet printing which film comprises a transparent or opaque substrate, having on at least one side therof an annotatable water-in-soluble, water-absorptive and ink-receptive matrix, said matrix comprised of a hydrogel complex and a pigment.
