ABSTRACT:
The invention provides an ink jet recording medium which attains the prevention of the bronzing of cyan ink and the prevention of the migration of magenta ink at the same time and is excellent in image characteristics. The ink jet recording medium comprises a substrate and an ink-receiving layer provided with at least an upper layer as the outermost layer and a lower layer as a layer lying just under the upper layer, both layers having a porous structure formed of an alumina hydrate and a binder, wherein both of the upper and lower layers contain an alkylsulfonic acid and only the lower layer contains a cationic polymer.
