Abstract
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.
Claims20
An ink jet recording medium, comprising a base substrate that has coated on a surface thereof a polymer matrix coating that can receive a pigmented ink and which contains at least one layer having 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 greater than or equal to about -20% and a swellability greater than or equal to about 50%.
An ink jet recording medium, comprising a base substrate that has coated on a surface thereof a polymer matrix coating that can receive a pigmented ink and which contains at least one layer having 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 greater than or equal to about -20%, and a swellability greater than or equal to about 50%;
- and
- said polymer matrix coating comprising a water-soluble component which is soluble in water in an amount of about at least 1% on a wt/wt basis of the water-soluble component in water at a temperature in the range of about 5.degree. C. to about 100.degree. C.
