  • Polymer matrix coating for ink jet media
    Patent number: 5700582
    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.
