Estimating the term…
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.
A coated substrate for ink-jet ink printing, said coated substrate having a printing surface and an opposing back surface, said printing surface comprising a coating formulated for accepting an ink-jet ink composition, and said back surface comprising a coating formulated for repelling said ink-jet ink composition.
Ink-jet ink printing media, comprising:
A composite coating material for overcoating hydrophilic coated printing media, comprising:
A coated substrate for ink-jet ink printing, said coated substrate having a printing surface and an opposing back surface, said printing surface comprising a coating formulated for accepting an ink-jet ink composition, and said back surface comprising a backcoating formulated for repelling said ink-jet ink composition, said backcoating further comprising a hydrophobic polymeric binder blended with a natural wax.
