録材及び記録方法に関する。Detailed Description of the Invention (Industrial Application Field) The present invention relates to a recording material suitably used in an inkjet recording method, and in particular has excellent water-based ink absorption and coloring properties, and is capable of producing fine and clear recorded images with high rust. The present invention relates to a recording material and a recording method suitable for providing.
更に本発明は記録画像の保存性、特に耐水性に優れた被
記録材及びそれを用いる記録方法に関する。Furthermore, the present invention relates to a recording material with excellent storage stability of recorded images, particularly water resistance, and a recording method using the same.

等が知られている。(Prior art) Conventionally, recording materials for inkjet use include: (1) general paper containing valves as its main component and made into a paper of low size to resemble filter paper or blotting paper; (2) A coating layer is provided on a base material using a pigment such as silica or zeolite that has 7τ pores, has a large oil absorption ti1, and adsorbs the coloring component in the ink.

と呼ばれる現象が生じてドツトが円形にならずギザギザ
になる現象やドツトが大きくなり過ぎて解像度の低下を
きたし、良質な画像が得られないという欠点があった。Although the above recording material (1) is low cost and has excellent ink absorption, the ink penetrates deeply into the fiber layer of the paper, so the coloring property of the coloring material in the ink is 3 (3), and the ink is absorbed along the fibers on the paper surface, a phenomenon called feathering occurs, which causes the dots to become jagged instead of circular, and the dots to become too large, resulting in a decrease in resolution and the ability to obtain high-quality images. There was a drawback that there was no
このため、専らこの様なノンコートタイプの紙は、モノ
クロ記録やパソコンの端末等の比較的解像度が低く高濃
度の画像を必ずしも必要としない用途に用いられてきた
。For this reason, such non-coated paper has been used exclusively for monochrome recording, personal computer terminals, and other applications that do not necessarily require images with relatively low resolution and high density.
上記被記録材(2)では、従来、例えば、特開昭58−
132586号公報及び特開昭59−35977号公報
にある様に、比較的サイズ度の高い紙(市販の上質紙等
)を基紙としたコート紙が用いられてきた。The recording material (2) has conventionally been used, for example, in JP-A-58-
As disclosed in Japanese Patent Application Laid-open No. 132586 and Japanese Patent Application Laid-open No. 59-35977, coated paper based on relatively high-sized paper (such as commercially available wood-free paper) has been used.
こうしたコート紙では、インク吸収層が多孔質で均一に
なっているため、適度なインク吸収性とドツト形状や解
像度に優れた画像が得られる。In such coated paper, the ink absorbing layer is porous and uniform, so images with appropriate ink absorbency and excellent dot shape and resolution can be obtained.

塗工層が基紙より剥れる、いわゆる粉落ちの問題が発生
する。このような紙粉は装置内部を汚すだけでなく、イ
ンクジェットヘッドのノズル詰りの原因にもなり特に問
題である。However, in a recording method that requires color images of higher quality and resolution, it is necessary to absorb and fix more ink at high speed. Conventionally, this has been dealt with by increasing the coating amount of the ink absorption layer and increasing the void volume of the ink absorption layer, but as the coating layer becomes thicker, the recording material becomes more difficult to handle, such as in the conveyance system of the recording device. When the coating layer comes into contact with the base paper, the coating layer peels off from the base paper, which causes a so-called powder-shedding problem. Such paper dust not only stains the inside of the apparatus, but also causes nozzle clogging of the inkjet head, which is a particular problem.

が激しく起こる。乾燥条件を緩やかにしたり、例えば、
塗工回数を数回に分けて行うことによりこのような問題
は幾分は解決されるが、この場合には製造コストが高く
なるという聞届もある。Furthermore, in the manufacturing process, a large amount of the coating liquid must be rapidly dried, which causes migration of the binder in the coating liquid, resulting in a severe decrease in the strength of the coating layer and ink absorption. By relaxing the drying conditions, for example,
Although such problems can be solved to some extent by dividing the coating into several coats, there are reports that this increases manufacturing costs.
これらの欠点を解決する方法として、基紙としてサイズ
度の低い紙を用いて、その上に多孔質の顔料層を設ける
方法か挙げられる。例えば、特開昭59−185690
号公報にはサイズ度4秒以下の基紙上に特定の物性を有

いる。One method for solving these drawbacks is to use paper with a low sizing degree as the base paper and provide a porous pigment layer thereon. For example, JP-A-59-185690
The publication exemplifies a recording material having a coating layer containing silica having specific physical properties on a base paper having a size degree of 4 seconds or less.

点がある。(Problems to be Solved by the Invention) This type of recording material has the advantage that even when a relatively thin ink-receiving layer is provided, a recording material with excellent ink absorption properties can be obtained.

ンク中の染料の耐水性が低くなること、等の問題点を有
している。However, even with such recording materials, (1) a large amount of ink penetrates deeply into the base paper, resulting in low print density; (2) the ink-receiving layer is thin and cannot hold much ink, so the base paper When the ink is absorbed by the navigation recording material (1)
Deterioration of resolution and print quality due to poor dot shape or excessive smearing of adhered ink droplets as mentioned in (3) The binder being applied during coating is absorbed into the low-size base paper, resulting in (4) The dye in the ink cannot be retained in the ink-receiving layer and is absorbed by the base paper, resulting in poor water resistance, etc. It has the following problems.

来、これら相互の物性に着目してF記の問題点を解決す

It has not been done.

い。In addition, according to the knowledge of the present invention, in particular, the bleeding and dot shape of ink droplets attached to the recording material are greatly affected by the ash content of the base paper in this type of paper, and the ash content is less than 2%. In some cases, the adhered ink droplets smear significantly along the fiber direction of the surface of the base paper, resulting in poor dot shape and the smearing of the ink droplets being larger than necessary. On the other hand, if it exceeds 15%, it is not preferable because the recording material itself will lose its stiffness and powder will fall off from the base paper.

層も含むものとする。Although the size degree of the base paper used in the present invention is not particularly limited, the size degree of the base paper is preferably in the range of 4 to 15 seconds. In particular, if the size of the base paper is less than 4 seconds, the binder in the coating liquid will be significantly absorbed into the base paper during coating.
This is undesirable because powder falls off on the surface of the coating layer. The sizing degree of the base paper referred to here is a value adjusted by adding an internal sizing agent 111 during paper making, and the surface size includes the coating layer.

明の方法に有効である。The methods described above are suitable for the method of the present invention.To explain some of them, there is an electrostatic attraction method. A method in which a strong electric field is applied between the ink particles and the ink particles are drawn out one after another from a nozzle, and an information signal is given to the deflection electrodes while the drawn ink flies between the deflection electrodes to record the information. There is a method in which ink particles are ejected in response to an information signal without having to do so, and either method is effective for the method of the present invention.

ができる点である。The second method is to apply high pressure to the ink using a small pump and mechanically vibrate the nozzle using a crystal oscillator, etc., to forcibly eject microscopic ink particles. At the same time as injection, +? It is charged according to the r-report signal. When the charged ink particles pass between the deflection electrode plates, they are deflected according to the weight of the band. Another method using this method is called the microdot inkjet method. In this method, ink pressure and excitation conditions are maintained at appropriate values within a certain range, and two types of ink droplets, large and small, are ejected from the nozzle tip. Only the medium- and small-diameter ink droplets are used for recording. A feature of this method is that it is possible to obtain a group of microdroplets even with a nozzle diameter as large as that of conventional methods.

方式である。A third method is a piezo element method, in which a piezo element is used as a pressure means for applying pressure to the ink, rather than a mechanical means such as a pump as in other methods. This method applies an electric signal to a piezo element to cause mechanical displacement, thereby applying pressure to the ink and ejecting it from a nozzle.
