Embodiment 1

[0064] The porous film containing amorphous silica manufactured by PPG Co. "Teslin TM "Make base layer. This porous film thickness is 180 microns, and porosity is 65% (volume), and pore size is 0.01-1 micron. The acrylic adhesive layer (thickness=30 microns) of liner is laminated on one side of base layer ).

[0065] On the non-adhesive side of the prepared base layer having an adhesive layer, the hydrophilization treatment solution of the following composition was applied and dried.

[0066] Surfactant (Pelex TM TR, manufactured by Kao Corp.)

Embodiment 2

[0083] Embodiment 2 (comparative example)

[0084] The procedure described in Example 1 was repeated except that no aluminum sulfate was added to the coating solution for forming the ink characteristic receiving layer for comparison. Printing test 1 was performed. The result is as follows.

[0085] With a drying time of 80 seconds, the ink showed sufficient water resistance, but a large degree of staining occurred at the border (300%). It is considered that this contamination is caused by a decrease in ink fixing force. Compared with Example 1, its color development was unclear.

Embodiment 3

[0087] The steps described in Example 1 were repeated, except that the surface of the base layer was not subjected to hydrophilic treatment in this example. Printing test 1 was performed. The result is as follows.

[0088] With a drying time of 40 seconds, this ink is considered to dry relatively slowly. But almost no contamination was observed at the border (300%). Its color rendering is excellent enough to be compared with Example 1.

Abstract

Provided is an ink image recording medium with excellent color rendering properties, which can effectively prevent the coloring components in the ink from transferring into the micropores of the medium. The image recording medium comprises (i) a substrate layer containing permeable micropores and (ii) an ink image-receiving layer containing a water-soluble salt as a coagulant, which layer is placed on the surface of the substrate layer, and the substrate layer is activated by a surfactant. The bottom layer and the inner surface of micropores are hydrophilic, and the ink image receiving layer contains polar organic polymers.

Description

field of invention [0001] The present invention relates to an image recording medium, and more particularly, the present invention relates to an image recording medium for recording an ink image by a printing method such as an ink jet recording method. The image recording medium according to the present invention is capable of forming or recording an image having high ink drying performance (water-fastness) and high water repellency. Background of the invention [0002] Hitherto, materials having a porous base layer containing many permeable micropores have been known as ink image recording media such as ink jet recording paper. For example, International Publication No. WO99 / 03685 discloses an ink image recording medium comprising a base layer composed of a porous thin film containing a surfactant and a multivalent metal salt in pores of the base layer. The polyvalent salt is immobilized in the micropore by making the inner wall (inner surface) of the micropore of the base...
