| 简介 |
The object of the present invention is to provide an ink jet recording medium which is high in gloss and ink absorption and excellent in image colorfulness and adhesion of the coats and a method for producing the same. According to the present invention, there is provided an ink jet recording medium which comprises a support, an undercoat layer containing a salt of an alkaline earth metal and an adhesive provided on the support and an ink-receiving layer provided by coating a coating solution containing inorganic ultrafine particles on the undercoat layer. The undercoat layer preferably contains the adhesive in an amount of 0.05-0.8 time the amount of the salt of alkaline earth metal in weight ratio. Furthermore, the undercoat layer preferably contains an organic pigment. The alkaline earth metal is preferably calcium or magnesium, and more preferably the salt of the alkaline earth metal is a carbonate. The inorganic ultrafine particles are of an amorphous synthetic silica produced by a gas phase method or an alumina compound. There is further provided a method for producing the ink jet recording medium according to which the ink-receiving layer is provided after the undercoat layer is coated and subjected to a hot calendering treatment. |
