関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a matte coated paper excellent in smoothness, ink acceptability, printing smoothness and printing gloss.

なく、読み易いため、広い方面に利用されている。2. Description of the Related Art In recent years, the visualization of printed matter has progressed, and the demand for quality of coated paper for printing has become stronger and stronger. Traditionally,
The matte coated paper has a high white gloss and gives an elegant feeling compared to the coated paper for printing having a high printing gloss, and at the same time, when used as a text sheet, there is no glare on the surface, It is widely used because it is easy to read.

紙は、通常の印刷用塗被紙に比較して、平滑性、インキ
受理性、印刷平滑及び印刷光沢が劣っている。Matte coated paper has a base paper coated with a coating liquid containing a large amount of a pigment relatively coarser than the pigments used for ordinary printing coated papers in order to suppress white paper gloss. Moreover, in order to keep the glossiness of the white paper low, the calendering process is extremely light or may not be applied at all. Therefore, the matte coated paper is inferior in smoothness, ink acceptability, print smoothness and print gloss to the ordinary printing coated paper.
【０００４】これらの問題点を解決するために、原紙の

度、剛直度の低下を引き起こす。However, there is a limit to improving the smoothness by improving the texture, and especially for a low basis weight base paper, N
The amount of timber used is large and it is difficult to deal only with the formation. On the other hand, strengthening the machine calender is effective in improving the smoothness of the base paper, but with a normal blade coater where the smoothness of the coated paper is most easily obtained, coating defects such as streaks and scratches are caused, which is not preferable. . Further, when dealing with the problem after coating, a calendering process can be considered, but strong calendering causes an increase in glossiness of white paper and a decrease in opacity and rigidity.

As a result of intensive research aimed at manufacturing, the present invention has been completed.

たものであることを特徴とする。The matte-coated paper of the present invention is a matte-coated paper in which the base paper for coating has a 10 second Cobb size degree of 10 to 30 g / m 2 and a smoother smoothness of 4
The coating liquid is bent blade coated and calendered under the condition that the coating length is 00 mmHg or less, and the contact length of the blade contacting the backing roll on the coating base paper is 2 to 5 mm. .
【０００９】以下、本発明の艶消し塗被紙について、詳
細に説明する。本発明の艶消し塗被紙において、塗被用
原紙のスムースター平滑度が４００ｍｍＨｇを超えて高
い場合、塗工後の塗被紙において十分な平滑性が得られ
ず印刷適性が悪くなる問題がある。The matte coated paper of the present invention will be described in detail below. In the matte coated paper of the present invention, when the smoother smoothness of the base paper for coating is higher than 400 mmHg, sufficient smoothness cannot be obtained in the coated paper after coating, resulting in poor printability. is there.

ブレードの接触長が狭い場合には、ブレード先端での線
圧が高くなり、進入してきた粒子を除去できなくなる。
その改善としては、バッキングロールに接触する接触長
を２〜５ｍｍに維持して塗工する方法が効果的である。However, even if the smoother smoothness of the base paper for coating is set to 400 mmHg or less, when the ordinary bevel blade coating is performed, foreign matter from the coating liquid or the base paper,
Alternatively, fine particle agglomerates in the coating liquid tend to be caught on the blade, resulting in coating defects such as streaks and scratches. Further, when the contact length of the blade that comes into contact with the backing roll is narrow, the linear pressure at the blade tip becomes high, and the particles that have entered cannot be removed.
As an improvement, a method of applying a coating while keeping the contact length of the backing roll to be 2 to 5 mm is effective.
【００１１】しかしながら、このような方法で塗工した
場合、接触時間が長くなること及び高い押し付け圧とな
ることから、塗被用原紙への塗被液の陥没が起こり易く
なるという欠点がある。However, when coating is carried out by such a method, the contact time becomes long and the pressing pressure becomes high, so that there is a drawback that the coating liquid is likely to sink into the coating base paper.
【００１２】この問題は、塗被用原紙のサイズ性を高く

０秒コブサイズ度が３０ｇ／ｍ2 を超えて高いと塗被液
の陥没が大きくなり、塗工適性が悪化する。This problem can be solved by increasing the size of the base paper for coating. That is, it is desirable that the 10 second Cobb size degree of the base paper for coating is in the range of 10 to 30 g / m 2 . Here, the 10-second bump size degree of the base paper for coating is 10
When it is less than g / m 2 , the penetration of the coating liquid into the coating base paper is too small and the strength of the coating layer is reduced.
When the 0 second Cobb size degree is higher than 30 g / m 2 , the coating liquid is largely depressed and the coating suitability is deteriorated.

Examples thereof include a method of internally adding a ketene dimer, a rosin sizing agent and the like to the pulp blending method, and a method of surface coating starch and a synthetic polymer agent and the like with a size press.
