example 1

[0097] Commercially available LBKP as a source pulp was beaten using a double-disc refiner to obtain a beaten papermaking stock (A) having 300 mL of Canadian Standard Freeness (C.S.F). Similarly, commercially available LBKP as a source pulp used as a base layer was beaten using the same equipment to obtain a beaten papermaking stock (B) having 450 mL of Canadian Standard Freeness (C.S.F). The beaten paper stock (A) and the beaten paper stock (B) were mixed at a dry weight ratio of 9:1 to prepare a paper stock.

[0098] Alumina hydrate liquid dispersion (solid matter content: 10% by weight) was prepared by dispersing alumina hydrate having the boehmite structure described in Example 1 of Japanese Patent Application Laid-Open No. 9-99627 in deionized water. A cationic resin liquid dispersion was prepared by dispersing a cationic resin, Weisstex H-90 (trade name, manufactured by Nagase Kasei Kogyo K.K., active ingredient content: 45%) in deionized water. The alumina hydrate liqu...

[0102] The beaten paper stock (A), the beaten paper stock (C) and the beaten paper stock (D) were mixed in a dry weight ratio of 8:1:1 to prepare a paper stock. Paper was manufactured using the same paper machine as in Example 1 so as to have the same paper basis weight as in Example 1. Then, coating was performed with the same on-machine coating liquid in the same manner and in the same amount as in Example 1. Smoothing the paper is carried out in the same manner as in Example 1. Thus, a recording medium is obtained. Its feel is similar to traditional plain paper. Table 1 shows the properties of the resulting recording media.

[0103] Typical effects of the present invention are as follows:

[0104] (1) Excellent ink absorption performance can be obtained without causing sticking of paper or ink strike-through, even if printing is performed on an ultra-high-speed printer having a solid line head.

[0105] (2) Even at high-speed printing, excellent color developing perfor...

Abstract

A recording medium having a non-sized single-layer fibrous structure which is composed mainly of a fibrous material and contains no filler and employing a face of the single-layer fibrous structure as an ink-receiving face, wherein alumina hydrate of a boehmite structure and a cationic resin are present at least near the surface of the fibrous material.

Description

technical field [0001] The present invention relates to a recording medium suitable for recording using ink, which has excellent ink absorbency, can maintain the feel of ordinary paper on the surface, and can give high image density and clear image tone. The present invention also relates to a process of manufacturing the recording medium, and an image forming method using the recording medium. Background technique [0002] The inkjet recording device uses various ejection principles to eject fine ink droplets on a recording medium similar to paper to record images, images, and text. The inkjet recording device has the characteristics of high printing speed, low noise, easy color printing, flexible recording method, no need for image development and fixing, and the like. Therefore, the inkjet recording apparatus has gradually been widely used as an image forming apparatus for information recording and other application fields. [0003] In addition, images formed by a colo...
