Recording sheet

摘要

A recording sheet for use with inkjet printers which achieves high color density while being free of bleeding is provided. The recording sheet has an ink-receiving layer and an ink permeable layer arranged on a surface of the ink-receiving layer. The ink permeable layer includes a filler, a surfactant, and a binder. The surfactant includes a fluorosurfactant having perfluoro-alkyl groups in its chemical structure. The ink permeable layer is made hydrophobic as well as lipophobic since hydrophilic groups on the surfaces of the filler particles will be covered by perfluoro-alkyl groups of the fluorosurfactant. This prevents aqueous ink added an organic solvent from dispersing within the ink permeable layer. The ink permeable layer includes a binder containing a water-insoluble resin having a hydroxyl value of 4 or higher (mgKOH/g) to lower the affinity to the ink.
