Abstract

An inkjet-recording medium has excellent various preservabilities, for example, the lightfastness of an image, resistance to bleeding under high-temperature and high-humidity conditions, and resistance to indoor fading and discoloration when a surface of a printing paper is subjected to laminating treatment. In an inkjet-recording medium having an ink-receiving layer on one surface of a base, the base having abilities to absorb and retain an ink solvent, a low oxygen-permeable resin layer preferably having an oxygen permeability of 10 cc/(m²·D·atm) at a temperature of 20° C. and at a relative humidity of 90% is provided on another surface of the base.

Claims

1. An inkjet-recording medium having an ink-receiving layer on one surface of a base with an ability to absorb an ink solvent, the inkjet-recording medium comprising:

a low oxygen-permeable resin layer provided on another surface, which is remote from the ink-receiving layer, of the base.

2. The inkjet-recording medium according to claim 1, wherein the base has a first region far from the ink-receiving layer and a second region near the ink-receiving layer along the thickness direction, the permeability of the first region to the ink solvent being greater than that of the second region.

3. The inkjet-recording medium according to claim 1, wherein the base comprises paper or a porous resin.

4. A method for forming an inkjet print, comprising the steps of:

forming an inkjet image at an ink-receiving layer of an inkjet-recording medium comprising a base and a low oxygen-permeable resin layer; and

laminating an image-protecting layer principally composed of a thermoplastic resin on the ink-receiving layer with the inkjet image, the ink-receiving layer being disposed on one surface of the base, the low oxygen-permeable resin layer being disposed on another surface of the base remote from the ink-receiving layer, wherein the base has an ability to absorb an ink solvent.

5. An inkjet print produced by a method comprising the steps of:

forming an inkjet image at an ink-receiving layer of an inkjet-recording medium comprising a base and a low oxygen-permeable resin layer; and

laminating an image-protecting layer principally composed of a thermoplastic resin on the ink-receiving layer with the inkjet image, the ink-receiving layer being disposed on one surface of the base, the low oxygen-permeable resin layer being disposed on another surface of the base remote from the ink-receiving layer, wherein the base has an ability to absorb an ink solvent.
