发明名称 Newsprint papers
摘要 An object of the present invention is to provide a newsprint paper having a friction coefficient in an appropriate range, a sufficient sizing quality, a low "neppari" strength and excellent printability. A newsprint paper having a static friction coefficient in an appropriate range of 0.44-0.74, a sufficient sizing quality and a low "neppari" strength can be obtained by applying a coating solution containing an alkenyl ketene dimer represented by general formula 1 below and a paper surface-modifying agent on a newsprint base paper, especially a neutralized newsprint base paper containing 1% by weight or more and 30% by weight or less of calcium carbonate as a filler and 50% by weight or more of deinked pulp. wherein R1 and R2 represent an unsaturated hydrocarbon group containing 8-30 carbon atoms.
