Abstract: The present invention is drawn to compositions and coated substrates wherein a hydrophobic backside coating layer can be implemented for use that mitigates ink transfer, surface damage, smudging, and sticking between stacked sheets in output trays of ink-jet ink printers. The backside coating can comprise hydrophobic beads suspended in a polymeric blend having a hydrophilic polymeric binder component and a hydrophobic polymeric binder component. Alternatively, the coating can comprise a hydrophobic binder blended with a natural wax. Either coating can be applied directly to the backside of a media substrate or on top of an existing hydrophilic layer that is typically applied for curl and sheet feed performance.

Abstract: Ink-receiving print media products capable of producing high quality printed images which are light-fast, humid-fast, have low coalescence (graininess) levels, and are characterized by other beneficial attributes. The print media products have at least one ink-receiving layer supported by a substrate. The ink-receiving layer includes a binder blend designed to achieve the aforementioned goals, namely, gelatin, a poly(vinyl alcohol-polyethylene oxide) copolymer, and a poly((styrene)-(n-butyl acrylate)-(methyl methacrylate)-(2-(tert-butylamino) ethyl methacrylate)) copolymer. One or more optional pigments and/or additional binders can also be included within the ink-receiving layer. The ink-receiving layer may optionally be employed in combination with one or more additional material layers thereover or thereunder which can contain, for example, one or more pigments and/or binders.
