| 摘要 |
The present invention is drawn to a method of preparing a porous media substrate, comprising preparing a coating composition including metal or semi-metal oxide particulates, a polymeric binder, and at least one water soluble coating formulation additive; applying the coating composition to a media substrate to form an ink-receiving layer having a porous surface, wherein at least a portion of the water soluble coating formulation additive remains unreacted at the ink-receiving layer; and removing at least a portion of the water soluble coating formulation additive from the ink-receiving layer.
