    摘要： A recording material for back-printing contains (i) a back-printing sheet comprising a transparent substrate, an ink-absorbing layer that is provided on the transparent substrate, and a porous ink-receiving layer that is provided on the ink-absorbing layer and has filler dispersed in a binder resin, and (ii) a back-printing sheet cover film having a cover substrate, and an adhesive layer that has an adhesive resin and is formed on the cover substrate, the refractive index of the filler and the refractive index of the adhesive resin are different to one another. Specifically, the difference between the refractive index of the filler and the refractive index of the adhesive resin is at least 1.0.

    摘要： A recording sheet adaptable to print an image using pigment ink, on which a smear is hardly generated, is provided. A recording sheet includes an ink permeable layer prepared by adding 3-30 parts by weight of a nonionic surfactant including an amine compound as a main component to 30 parts by weight of a water-insoluble component including an inorganic filler and a binder as main components. Ink applied on such an ink permeable layer is directly absorbed into the layer in a depth direction without dispersing in a lateral direction. Therefore, any smear (banding) is hardly generated on a printed image formed on the recording sheet using ink.

    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.
