| titleOfInvention | Calcium carbonate pigment for coated paper and coated paper using the pigment |
| abstract | In the calcium carbonate slurry to which the dispersant is added, 0.1 parts by mass or more of aluminum sulfate is added to 100 parts by mass of calcium carbonate solid content, and the aluminum sulfate is stirred so as to cover each calcium carbonate particle, Then, an aqueous alkali solution containing at least one selected from sodium hydroxide, potassium hydroxide and ammonium hydroxide is added at a pH of 8 while stirring, and then the stirring is continued to prepare a slurry containing the calcium carbonate pigment of the present invention. To do. According to the present invention, it is possible to produce calcium carbonate pigments for coated papers for commercial printing papers, which are excellent in gloss development and ink absorbability, and in an extremely small amount of alkali such as aluminum sulfate and sodium hydroxide. Thus, there is provided a method for producing a pigment that has a short working time, extremely good workability, good rheological properties, and can be applied at high speed by a high speed coating machine. |
