Abstract
A porous resin film which comprises 30 to 90 wt % of a thermoplastic resin containing a hydrophilic thermoplastic resin component; and 70 to 10 wt % of an inorganic or organic fine powder was disclosed. The porous resin film of the present invention is valuable as an ink-jet recording medium since the film shows excellent ink absorbing and drying properties even when a large amount of ink is discharged thereon, and thus can produce thereon a high-definition image.
