ABSTRACT:
A recording medium for ink, capable of rapidly absorbing large amounts of ink, showing excellent color forming ability and capable of suppressing image deterioration caused by dye displacement that occurs when an image is stored in humid conditions and image deterioration caused by light when a printed image is displayed, and providing a printed image showing excellent long-term stability. The invention also provides a recording medium for ink having at least one layer provided on a substrate, and an ink receiving layer containing alumina hydrate as an outermost layer. A surface of the substrate at least on the side of the ink receiving layer is subjected to a cationizing treatment. An undercoat layer is provided on the same side as the cationizing treatment, to obtain cations in a predetermined distribution. The outermost ink receiving layer is provided on the undercoat layer.
