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.

Coated media for improved output tray stacking performance

A recording medium comprising a substrate coated with at least one ink receiving layer and at least one protective layer which comprises polymeric particles having film forming temperatures between 60 to 140&deg; C., preferably between 100 to 120&deg; C., and at least one binder. In the related printing method, the printed medium is heated to form a stable image protecting coating.
