る。2. Description of the Related Art Conventionally, in order to improve surface properties such as smoothness, gloss, and printability of paper, a slurry-like coating liquid obtained by adding a white pigment such as kaolin and a binder to an aqueous medium is applied to the paper. Coating is well known. In this case, as a coating method, generally, the coating liquid from the preparation tank is supplied to the coating head to coat the running paper, and the excess coating liquid is removed with a blade or the like and returned to the tank. The method of circulating the coating liquid is widely adopted, such as mixing with a new coating liquid and using it again for coating.

する要望が高まってきている。On the other hand, in recent years, in order to improve productivity,
Paper coating has been actively performed at a higher coating speed (about 1400 m / min or more) than the conventional coating speed (about 1000 m / min), so it should be coated under high-speed operation. There is an increasing demand for a paper coating liquid which can produce a coated paper of good quality.

公報）。By the way, as the above-mentioned paper coating liquid, one containing clay, ground calcium carbonate, latex, oxidized starch and a dispersant is generally used.
A small amount of a water-soluble polymer substance such as sodium alginate or carboxymethyl cellulose (CMC) is added to such a coating liquid in order to adjust the viscosity and fluidity of the coating liquid. Further, in order to obtain a coating liquid excellent in water retention, viscosity and fluidity, a copolymer of acrylic acid and methacrylic acid, a copolymer of unsaturated carboxylic acid and unsaturated carboxylic acid ester and a polyol compound are used. It has been proposed to add a small amount of the additive (Japanese Patent Publication No. 9238/1992).

になる。However, the additives conventionally used for controlling the viscosity and fluidity of the coating liquid are blended in the coating liquid in an amount such that the B-type viscosity of the coating liquid is appropriate. In this case, since the high shear viscosity of this coating liquid increases, it becomes difficult to adjust the coating liquid amount on the paper surface with a blade etc. when coating at high speed (about 1400 m / min or more), There is a drawback that the coating liquid adheres more than necessary, and as the viscosity of the coating liquid at high shear increases, the fluidity of the coating liquid deteriorates and streaks on the surface of the resulting coated paper. , Spits, scratches, etc., and the surface properties such as gloss, smoothness and printability of the coated paper (print gloss during printing and wet inking property) are remarkably impaired. Furthermore, the coating liquid containing the above-mentioned additive has a large change in viscosity with time, and when the coating liquid is circulated and used many times, the viscosity of the coating liquid largely increases, resulting in deterioration of workability and coating. It causes deterioration of quality of craft paper.

キレンオキシド付加物の作用により、このような問題は
生じない。The paper coating liquid of the present invention comprising such an aqueous suspension has a low viscosity at high shear and is extremely excellent in high speed coating property. In the case of a conventional coating liquid, when it is applied to the surface of paper running at a high speed (for example, about 1400 m / min or more), a large shearing force is applied to the coating liquid to increase the viscosity of the coating liquid, As a result, it becomes difficult to control the coating amount of the coating liquid on the paper surface, and unnecessary amount of coating liquid adheres to the paper surface, or streaks, spits, scratches, etc. occur on the coating layer surface. The gloss and smoothness of the surface of the layer decrease, and further, during printing, there is a decrease in print gloss and a lack of wet ink receptivity. On the other hand, the coating liquid of the present invention does not cause such a problem due to the action of the alkylene oxide adduct of the higher alcohol which is the component (C).

Further, in the coating liquid of the present invention, since the alkylene oxide adduct of higher alcohol acts as a lubricant, the pigment concentration or the solid content concentration in the coating liquid is high, for example, about 60 to 65% by weight, The coating liquid has good coatability and can be smoothly coated on the surface of the paper substrate.
