Abstract: An ink jet recording medium having an ink receiving layer formed on a substrate, wherein an ink fixing agent contained in the ink receiving layer is a serpentine compound containing at least one metal selected from the group consisting of Mg and Zn, and an ink fixing agent which comprises a serpentine compound containing at least one metal selected from the group consisting of Mg and Zn and is used in the ink jet recording medium. According to the present invention, an ink jet recording medium having excellent ink absorptivity (color development, resolution) and excellent water resistance and light resistance for an image recorded on the medium can be provided by using a serpentine compound as an ink fixing agent. That is, according to the present invention, there can be provided an ink jet recording medium which is best suited for recording with a water/oil ink, can record a high-definition image at a high reproducibility and has excellent keeping properties, especially water resistance and light resistance.

Abstract: A dye fixing agent for water-color ink to be contained in the water-color ink accepting layer of an ink jet recording medium having an water-color ink accepting layer formed on a substrate, which is a hydrotalcite compound containing a silicic acid anion and a sulfuric acid ion, or a silicic acid anion as an anion(s). An ink jet recording medium comprising the dye fixing agent for water-color ink formed on a substrate. The dye fixing agent for water-color ink of the present invention is excellent in the fixability of water-color ink, the resolution of an image recorded on a medium, water resistance and light resistance.
