    • PURPOSE: To obtain a paper-coating resin especially, good in water resistance effect and ink receptivity, by reacting a polyalkylenepolyamine with an alicyclic dicarboxylic acid, a urea and an alkylating agent and, optionally, formaldehyde and/or glyoxal.
      CONSTITUTION: polyalkylenepolyamine (a) is reacted with an alicyclic dicarboxylic acid and/or a free carboxyl group-containing reaction product (b) obtained by a reaction of an alicyclic dicarboxylic acid with a glycol, a urea (C), an alkylating agnet (d) and, optionally, formaldehyde and/or glyoxal (e). By using an alicyclic dicarboxylic acid instead of the conventional aliphatic or aromatic dicarboxylic acid, the performance of the resin can be prominenetly improved. In order to react components (a)W(e) with each other, a reaction product among components (a), (b) and (c) is reacted with component (d) and, optionally, component (e).

    • PROBLEM TO BE SOLVED: To provide offset paper having good printing quality and printing operability by effectively improving surface strength of the paper such as a vessel pick strength by applying a small amount of a surface treating agent, suppressing elongation of paper during transfer of dampening water in the offset printing and preventing reduction of tension and color displacement during running of a web rotary offset press.
      SOLUTION: This offset paper is prepared by applying the surface treating agent containing a promoter for increasing strength of wet paper to a printing base paper sheet and drying the paper sheet. Preferably, a polyamide polyamine epichlorohydrine resin is used as the promoter and applied to the base paper sheet in an amount of 0.005-1.0 g/cm
      2 based on the solid on one surface of the base paper sheet.

    • 要解决的问题:通过施加少量的表面处理剂,通过有效地提高纸的表面强度,例如容器选择强度来提供具有良好的印刷质量和印刷可操作性的胶印纸,抑制纸张在转印期间的伸长率 在胶版印刷中润湿水,并防止卷筒纸胶版印刷机运行期间的张力和颜色位移减小。

      解决方案:通过将含有增强湿纸强度的促进剂的表面处理剂涂布到印刷原纸上并干燥纸张来制备该胶印纸。 优选地,使用聚酰胺多胺表氯醇树脂作为促进剂,并且以原料纸的一个表面上的固体为基础,以0.005-1.0g / cm 2 SP / 2的量施加到原纸上。 版权所有(C)2004,JPO
