    摘要: Provide a newsprint paper for offset printing that offers good printing efficiency and print quality, wherein the paper, despite a high content of deinked pulp, notably suppresses show-through in offset printing and also reduces paper powder deposit on the blanket cylinders of the press. Adding a filler or fillers by more than 15 percent by weight but less than 40 percent by weight as ash relative to the paper weight notably suppresses show-through of a newsprint paper for offset printing. In particular, adding calcium carbonate with an average grain size of 0.5 to 5 μm and zeta potential of 0 mV or above by more than 15 percent by weight but less than 40 percent by weight as ash relative to the paper weight not only suppresses show-through further but also reduces the paper powder deposit on the blanket cylinders of the press.

    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.
