Problems solved by technology

However, in the case of forming an image on a recording medium using a line-type recording head and a single-pass method, the image cannot be drawn repeatedly because the recording head passes over the recording medium only once
Therefore, especially in the case of using plain paper as a recording medium, it is easy to cause a decrease in the density (print density) of the formed image and a problem of bleeding.
[0004] Also, when an image is formed on a recording medium using a line type recording head and a single-pass method, the ink penetrates excessively into the recording medium, and the image can be seen coming through even on the side (back) on which no image is formed on the recording medium. , prone to ink bleeding to the back
Thus, in the case of forming an image on a recording medium using a line type recording head and a single pass method, the quality of the formed image may be very poor

[0017] Hereinafter, the ink according to the first embodiment of the present invention will be described. The ink according to the first embodiment contains a pigment, first particles containing a first resin, second particles containing a second resin, and a humectant. The first resin contains repeating units derived from methyl methacrylate (hereinafter, sometimes referred to as MMA units) at a ratio of 30% by mass to 70% by mass relative to all repeating units. In the second resin, the content of MMA units is less than 30% by mass relative to all repeating units. In addition, the content ratio of the MMA unit in the second resin may be 0% by mass. That is, the second resin may not contain MMA units. The humectant contains α,ω-alkanediol.

[0018] Since the ink according to the first embodiment has the above-mentioned structure, it is possible to use the ink to increase the print density of the image formed on the recording medium while ensuring excellent ejection s...

[0073] Next, the inkjet recording system according to the second embodiment of the present invention will be described. The inkjet recording system of the second embodiment includes a conveying unit and an inkjet recording head (hereinafter, sometimes referred to as a “recording head”), and the conveying unit conveys a recording medium. In the inkjet recording system of the second embodiment, the ink of the first embodiment is used. Hereinafter, the inkjet recording system of the second embodiment will be described with reference to the drawings. In addition, for ease of understanding, the drawings mainly schematically show each structural element, and for the convenience of drawing, the size, number, etc. of each structural element shown in the drawing may differ from actual ones.

Abstract

The invention provides inkjet ink and an inkjet recording system. The inkjet ink includes a pigment, first particles containing a first resin, second particles containing a second resin, and a moisturizing agent. The first resin includes a repeating unit derived from methyl methacrylate at a content percentage of at least 30% by mass and no greater than 70% by mass relative to all repeating unitsincluded in the first resin. The second resin has a content percentage of the repeating unit derived from methyl methacrylate of less than 30% by mass relative all repeating units included in the second resin. The moisturizing agent includes an alpha, omega-alkanediol. In the inkjet recording system (100), a plurality of nozzles eject the inkjet ink to form dots on a recording medium conveyed by the conveyance section.

Description

Technical field [0001] The present invention relates to ink for inkjet and an inkjet recording system. Background technique [0002] As the recording head of the inkjet recording system, a linear recording head is known. In addition, inkjet printing methods include, for example, a multi-stroke method and a single-stroke method. The multi-stroke method refers to a method in which the recording head is moved back and forth on the recording medium several times while ejecting inkjet ink (hereinafter, sometimes abbreviated as "ink") from the recording head. The single-stroke method refers to a method in which the recording head passes through the recording medium only once and the ink is ejected from the recording head at the same time. The single-stroke method has the advantage of achieving high-speed printing. [0003] Therefore, from the viewpoint of increasing printing speed, an image forming apparatus in which a linear recording head and a single-stroke method are combined is b...
