(57) Abstract: An object of the present invention is to provide an ink jet recording medium having high gloss, high ink absorptivity, excellent image coloration, and having little ripple after recording, and a method for producing the same. Things. An ink jet recording medium comprising a base paper, an undercoat layer containing a salt of an alkaline earth metal and an adhesive, and an ink receiving layer containing inorganic ultrafine particles applied thereon. This is an inkjet recording medium provided with a barrier layer containing a pigment and an adhesive between a base paper and the undercoat layer. Preferably, the alkaline earth metal is calcium carbonate. Further, it is preferable that the inorganic ultrafine particles are amorphous synthetic silica prepared by a gas phase method. Further, it is a method for producing an ink jet recording medium in which after applying an undercoat layer, a heat calendering treatment is performed, and then the ink receiving layer is provided. |
