| description | To provide paper having high print surface strength.SOLUTION: Paper comprises base paper and a coating layer, the coating layer including chemically-modified and fibrillated cellulose fiber. The chemically-modified and fibrillated cellulose fiber is obtained by treating chemically-modified cellulose with a double disc refiner that has DA and DB as two discs and DM as a disc therebetween, in which at least one of the DA and the DB or the DM are fixed and the other is rotated. The chemically-modified and fibrillated cellulose fiber has a cellulose I-type crystallinity of 50% or more, an anion conversion rate of 0.10-2.00 meq/g, and an average fiber diameter of more than 500 nm.SELECTED DRAWING: None
【課題】高い印刷表面強度を有する紙を提供する。【解決手段】原紙および塗工層を備える紙であって、前記塗工層がフィブリル化された化学変性セルロース繊維を含み、前記フィブリル化された化学変性セルロース繊維は、２個のディスクとしてＤＡおよびＤＢと、その間に存在するディスクとしてＤＭとを備え、前記ＤＡと、前記ＤＢまたは前記ＤＭの何れか一方が固定され、他方が回転するダブルディスクリファイナーを用いて化学変性セルロースを処理して得られた繊維であり、前記フィブリル化された化学変性セルロース繊維のセルロースＩ型の結晶化度が５０％以上であり、アニオン化度が０．１０〜２．００ｍｅｑ／ｇであり、平均繊維径が５００ｎｍよりも大きい、紙。【選択図】なし |
