Embodiment 1

[0152] Coating solution 1b for base coat at 15 g / m 2 The dry solids content was coated by an air knife coater onto the paper support prepared above and the coating was dried. Next, apply 15 g / m on the obtained base coat with a curtain coater 2 The coating solution A for the ink-receiving layer in solid content was dried and then dried to obtain the recording medium of Example 1.

Embodiment 2

[0154] The recording medium of Example 2 was prepared in the same manner as in Example 1, except that the coating solution 1c for an undercoat layer was used instead of the coating solution 1b for an undercoat layer in Example 1.

Embodiment 3

[0156] The recording medium of Example 3 was prepared in the same manner as in Example 1, except that the coating solution 1d for an undercoat layer was used instead of the coating solution 1b for an undercoat layer in Example 1.

Abstract

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.

Description

technical field [0001] The present invention relates to an inkjet recording medium and a method for producing the same, and more particularly to such an inkjet recording medium comprising a support, an undercoat layer on the support, and an inkjet receiving layer on the undercoat layer (which is formed by coating a coating solution containing inorganic ultrafine particles for the ink receiving layer). This inkjet recording medium has excellent coating adhesion, and has high gloss, high ink absorption, excellent image color and high smoothness. Background technique [0002] The inkjet recording system ejects ink droplets according to various operating principles and deposits them on a recording medium such as paper, thereby accomplishing the recording of images or letters. Recording systems have the characteristics that they perform these operations at high speed, generate little noise, can easily perform multi-color printing, have great versatility in recorded graphics, do ...
