摘要： Provide a paper offering good paper strength properties in terms of strength and stiffness, high smoothness and excellent printing quality by adjusting the ash content in paper to a range of 3 to 40 percent by solid weight and allowing the paper to contain a pre-coagulated filler having an average particle size of 10 to 80 μm as measured by the laser diffraction method, wherein such filler is obtained by processing a filler using a composite acrylamide copolymer comprising (A) an anionic polysaccharide and (B) a cationic and/or amphoteric acrylamide copolymer.

摘要： The present invention aims to provide printability improving agents and surface-treating agents capable of improving offset printability of papers, especially newsprint papers to be printed with offset inks as well as papers, especially newsprint papers that can be successfully printed with offset inks. According to a first aspect of the present invention, a printability improving agent comprising a cationic copolymer consisting of one or more hydrophobic monomer unit(s) selected from a specific group and a quaternary ammonium salt-containing monomer unit or a surface-treating agent comprising the printability improving agent and a water-soluble polymer material selected from a specific group is applied on the surface of a base paper, especially a newsprint base paper. According to a second aspect of the present invention, a hydrophobic monomer unit selected from a specific group and a quaternary ammonium salt-containing monomer unit is polymerized to give a cationic copolymer, which is then further polymerized with a hydrophobic monomer to give a copolymer. Alternatively, a hydrophobic monomer unit selected from a specific group and a quaternary ammonium salt-containing monomer unit is polymerized to give a cationic copolymer, which is further polymerized with a hydrophobic monomer in the presence of a surfactant to give a copolymer. A printability improving agent comprising the copolymer or a surface-treating agent comprising the printability improving agent and a water-soluble polymer material selected from a specific group is applied on the surface of a base paper, especially a newsprint base paper.
摘要翻译：本发明的目的在于提供可印刷性提高剂和表面处理剂，其能够改善纸，特别是用胶印油墨印刷的新闻纸的胶版印刷性，以及纸，特别是可以用胶印油墨成功印刷的新闻纸。根据本发明的第一方面，提供了一种包含阳离子共聚物的可印花改性剂，所述阳离子共聚物由选自特定基团和含季铵盐单体单元的一种或多种疏水性单体单元或表面处理剂组成，将可印刷性改进剂和选自特定组的水溶性聚合物材料施加在原纸，特别是新闻纸原纸的表面上。根据本发明的第二方面，将选自特定基团和含季铵盐的单体单元的疏水性单体单元聚合，得到阳离子共聚物，然后与疏水性单体进一步聚合，得到共聚物。或者，将选自特定基团和含季铵盐的单体单元的疏水性单体单元聚合，得到阳离子共聚物，其在表面活性剂存在下进一步与疏水性单体聚合，得到共聚物。包含共聚物或包含可印刷性改进剂的表面处理剂和选自特定组的水溶性聚合物材料的可印刷性改进剂施加在原纸，特别是新闻纸原纸的表面上。
