PURPOSE:To improve a printability and a handleability at the time of printing by a method wherein a chemical pulp made of a kenaf wood part is incorporated in a total pulp composition by a specific value or more, and the measured smoothness value of a base paper surface is determined to be more than a specific value. CONSTITUTION:A chemical pulp made of a kenaf wood part is incorporated in the amount of 10wt.% or more in a total pulp composition forming base paper. The measured value of a base paper surface by a regular reflection-type smoothness meter is determine to be 8% or more under a pressurizing condition of 20kg/cm<2>. In addition to the kenaf wood part chemical pulp, as a pulp forming base paper for pressure-sensitive copy paper, a hard-wood chemical pulp, a coniferous chemical pulp, a high-yield pulp, and others can be used. For applying a smoothening treatment to the base paper surface, a machine calender made of only metal rolls and mounted on the utmost rear part of a paper machine can be used, but a supercalender, a gloss calender, a soft calender, or the like, made of metal rolls and elastic rolls, is effectively used in an on-machine or off-machine state. |
