Abstract:
1. An ink-jet recording medium comprising: a support; and an ink receiving layer disposed on the support, the ink receiving layer containing at least fine polymer particles and having a porous structure, wherein secondary particles of the fine polymer particles constitute the porous structure of the ink receiving layer, wherein the fine polymer particles are selected from the group consisting of homo- or co-polymers of vinyl monomers, ester polymers, urethane polymers, amide polymers, epoxy polymers, and modified products and copolymers of these polymers, and the content of the fine polymer particles is 50% by mass or more of solid contents in the ink receiving layer, and wherein the ink receiving layer has a pore volume per unit thickness (A/B) of 2.0×10 wherein A is a pore volume (×10 B is a dry thickness (μm) of the ink receiving layer.
