Abstract
An ink/media set is provided having improved durability. The ink contains an aqueous medium and a dye or pigment dispersion as the colorant. The media has a coating that contains a hydrophilic polymer and a reactive component. The printed media is exposed to an energy source that binds the ink to the media coating, and renders the coating more durable.
