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 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.
