Abstract
The recording sheet has an ink-receiving layer and an ink permeable layer. The ink permeable layer is arranged on a surface of the ink-receiving layer and includes a filler and a binder. The binder contains as a primary component a water-insoluble polyester resin having a high hydroxyl value in the range of 25 to 65. The ink permeable layer has a significant ink phobicity. The ink permeable layer does not contain a surfactant and is low lipophilic. Thus, when it receives ink containing an organic solvent, the ink does not disperse within the ink permeable layer to provide printed images without bleeding.
