PROBLEM TO BE SOLVED: To provide a porous resin film excellently absorbing water as a solvent in a water-based ink or a water-based glue and to provide a recording medium capable of absorbing an ink without causing uneven density even when a large amount of an ink is discharged, that is, even in solid printing or the like in ink jet recording. SOLUTION: The porous resin film comprises a thermoplastic resin, an inorganic or organic fine powder and a hydrophilizing agent, and has a liquid- absorbing volume in the range of at least 0.5 ml/m2 measured according to the Japan TAPPI No. 51-87. |
