Abstract
The invention provides a recording medium for ink having an ink absorbing ability capable of absorbing ink of a large amount at a high speed, showing an excellent color forming ability and capable of suppressing an image deterioration by a dye displacement which tends to appear particularly in an image storage under a high humidity condition, and an image deterioration caused by light when a printed image is displayed, and showing an excellent stability with time of the printed image, and a method for producing such recording medium for ink. The invention also provides a recording medium for ink having at least one layer laminated on a substrate and including an ink receiving layer containing alumina hydrate as an outermost layer, in which a surface of the substrate at least on the side of the ink receiving layer is subjected to a cationizing treatment, further having an undercoat layer on the side of such cationizing treatment to obtain cations in a predetermined distribution, and having an outermost ink receiving layer laminated on said undercoat layer, and a producing method for such recording medium for ink.
