Abstract: A method for dehydrating a dispersion of a chemically modified pulp (oxidized pulp, carboxymethylated pulp, or cationized pulp) obtained by chemically modifying a pulp feedstock, characterized by dehydrating the dispersion of a chemically modified pulp by means of a screw press.

Abstract: A method for producing an anionically-modified cellulose nanofiber dispersion, the method comprising: preparing a dispersion containing anionically-modified cellulose; and defibrating the cellulose in the dispersion, wherein at least a part of hydroxyl groups in pyranose rings in the anionically-modified cellulose is modified by oxidation or substitution, and an electrical conductivity of the anionically-modified cellulose aqueous dispersion that is subjected to defibration is 500 ?S/cm or lower at a concentration of 1.0 wt %. The dispersion has high transparency.

Abstract: Herein provided are processes for preparing coated printing paper having good print quality by spray coating. Specifically, a coated printing paper is prepared by a process for preparing a coated printing paper having one or more coating layers on at least one side of a base paper, comprising the steps of: preparing a spray coating solution containing a pigment and an binder including a starch, wherein (a) the starch is present at 30-100% by weight of the total amount of the binder, and (b) the Brookfield viscosity measured at 30° C., 100 rpm is 300 mPa·s or less; and applying the coating solution by spray coating to form the outermost coating layer.
