る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink jet recording method, and more particularly to an ink jet recording method for recording a high print quality on uncoated paper such as plain paper.

利点がある。2. Description of the Related Art The ink jet recording method is one in which small droplets of ink are ejected by various mechanisms and adhered onto a recording sheet to form dots for recording, which is more noise-free than the dot impact type recording method. In addition, there are advantages that it is easy to make full color and high-speed printing is possible.

る。However, in ink jet recording, it is important to match the ink used and the paper,
If this matching is inadequate, the ink will bleed or the ink density will drop, and a high-quality image will not be obtained, and the ink absorption speed will be slow, making it unsuitable for high-speed recording, and making full-color difficult. Becomes So, conventionally,
As the ink jet recording paper, so-called coated paper is used as a special paper in which a recording layer containing a pigment capable of promoting ink absorption is provided on the surface of the base paper.

るパルプの叩解度を高くした記録紙が開発されている。However, since this coated paper is expensive because it is a special paper, it has been desired to obtain high quality ink jet recording by using inexpensive uncoated paper.
Therefore, as an uncoated paper type inkjet recording paper, a recording paper was developed in which a surface sizing agent (starch, polyvinyl alcohol, styrene-acrylic resin) was added, or the pulp used as the base paper had a high beating degree. ing.

とはできなかった。However, in the case of uncoated paper in which ink bleeding is suppressed by adding an excessive surface sizing agent, for example, the ink absorption speed decreases, and the beating degree is increased to reduce bleeding. In the case of uncoated paper, there are drawbacks such as reduced opacity and deterioration of formation, which makes it difficult to adapt to multi-color inkjet recording and also to single-color inkjet recording. Again, we were not able to obtain a satisfactory quality record.

874, Japanese Patent Application No. 4-356137). However, since inks for inkjet printers differ depending on manufacturers and models, their physical property values are also various. Therefore, there are many cases where a recording paper that is good for a certain model and a certain ink is not good for another model and a certain ink.

ていた。In addition, as the need for a color ink jet printer compatible with plain paper (non-coated paper) increases, the ink absorbency becomes more important. Therefore, in order to improve the ink absorbability, recording is performed. It tends to lower the surface tension of the ink. However, in the area where the surface tension of the recording ink is low, ink bleeding (deterioration of dot shape) cannot be prevented only by the conventional method such as adding a sizing agent to the recording paper, and new measures are sought. It had been.

The ink used in the inkjet recording method of the present invention uses water or a mixture of water and a water-soluble organic solvent as a solvent, and a surfactant, a viscosity adjusting agent, a surface tension adjusting agent, etc., are added as necessary. Among them, those having a surface tension γ 1 of about 24 to 70 dyn / cm are used in the present invention (see FIG. 1).

When it is less than 70%, it becomes difficult to suppress ink bleeding, and when it exceeds 70 dyn / cm, the drying property of the ink becomes insufficient. The inkjet recording paper used in the present invention has a critical surface tension of about 22 to 33 dyn / c.
Use m. Critical surface tension is 33 dyn / cm
When it exceeds, the ink absorbability is good, but the ink is likely to bleed and the recording density is lowered. On the contrary, if it is less than 22 dyn / cm, the ink absorbency becomes insufficient.

An acrylic resin, a styrene-maleic acid resin, a polyacrylamide resin, a petroleum resin, or the like can be used according to the purpose. In the present invention, among these, higher fatty acid cation sizing agents can be particularly preferably used from the viewpoint of suppressing ink bleeding. In addition to the above-mentioned surface sizing agent, hydrophilic resins (starch, polyvinyl alcohol, etc.), defoaming agents, water-soluble alkaline salts, dye fixing agents are used in the coating liquid applied to base paper for manufacturing inkjet recording paper. Agents, flow modifiers, dyes, etc. are also added as appropriate.
