    • PROBLEM TO BE SOLVED: To provide a method for producing coated paper for printing use, by providing at least one side of substrate paper with one or more coating layers by a curtain coating system; more specifically, without such troubles that a curtain coating film becomes nonuniform and discontinuous due to air entrained by the substrate paper, and/or the coating film contacts the substrate paper, is accelerated to a substrate paper-traveling speed and drawn to cause coating layer defects in the production of the coated paper for printing use produced by providing at least one or more coating layers, effecting reducing fine coating layer defects.
      SOLUTION: The method for producing the coated paper for printing use, includes providing at least one side of substrate paper with one or more coating layers, wherein at least one layer among the coating layers is provided by the curtain coating system, and a coating liquid for the coating layers has a tensile viscosity of 0.005-1 Pa s determined by CaBER method, at a Henky strain of 0-5.

    • 要解决的问题:提供一种用于制造用于印刷用途的涂布纸的方法,通过帘式涂布系统提供基材纸的至少一侧一个或多个涂层; 更具体地说,没有这样的麻烦,即由于基片纸夹带的空气和/或涂膜接触基片纸而使幕涂膜变得不均匀和不连续,被加速到基底纸移动速度并且被拉伸以形成涂层 通过提供至少一个或多个涂层而产生的用于印刷的涂布纸的生产缺陷,从而减少细涂层缺陷。 解决方案:用于印刷用涂布纸的制造方法包括:向基材纸的至少一面提供一层或多层涂层,其中涂层中的至少一层由帘式涂布系统提供, 涂层的涂布液在0-5的亨氏应变下,通过CaBER法测定的粘度为0.005-1Pa s。 版权所有(C)2010,JPO&INPIT
