    摘要: PROBLEM TO BE SOLVED: To provide a newsprint for offset printing which has sufficient sizing properties and hardly causing color shift even when multicolor printing is carried out.
    SOLUTION: The newsprint for the offset printing has a water resistant tensile strength of not less than 3.5 s, and a surface-treating agent coated on both surfaces of base paper. The surface-treating agent includes an adhesive, an alkylketene dimer-based surface-sizing agent, and a polymer-based surface-sizing agent. The newsprint can prevent color shift in printing because the water resistant tensile strength representing sizing properties and tensile characteristics, is high, can prevent wrinkling, paper break or the like caused by slippage and paper shift in printing, which becomes problems when the alkylketene dimer-based surface sizing agent is used, and also can prevent the occurrence of piling in printing.
