  • Printing medium comprised of porous medium
    Patent number: 5965244
    Abstract: Provided is a printing medium particularly useful for inkjet printing. The printing medium is comprised of a substrate and a coating layer. The coating layer comprises porous particles, a resin binder and colloidal particles, with the colloidal particle being of a size that is greater than the size of the pores of the porous particles, but smaller than the interstitial pores created by the porous particles. The printing medium allows one to realize high optical density and high image resolution, while also offering good mechanical properties, fast drying, good waterfastness and consistent performance in different environments.
