摘要： The invention improves a sizing effect even on paper containing no internal sizing agent and improves productivity by making solution polymerization in a small amount of an organic solvent. The invention provides a cationic surface sizing agent composed of a copolymer obtained by solution polymerization of (a) 15 to 35% by weight of a tertiary amino group-containing monomer, (b) 30 to 85% by weight of C1 to C4 alkyl (meth)acrylate, and (c) 1 to 50% by weight of styrenes in an organic solvent in the presence of a chain transfer agent. The copolymer may be subjected to cationization treatment with a quaternization agent. As a constituent monomer of the copolymer, 0 to 20% by weight of another copolymerizable vinyl monomer (d) may be contained. The cationic surface sizing agent is applied to paper.

摘要： It is an object to improve sizing performance and anti-plate-soiling property in offset printing, for example, in a cationic surface sizing agent to be used for coating base paper of newsprint paper, and as a means for solving the object, a cationic surface sizing agent is produced by quaternizing a copolymer having a weight average molecular weight ranging from 30,000 to 60,000 obtained by polymerizing (a) 20 to 40% by weight of a monomer containing tertiary amino group; (b) 10 to 80% by weight of a C4 to C18 alkyl ester of (meth) acrylic acid; and (c) 0 to 70% by weight of a styrene or derivative thereof, using an azoic polymerization initiator in the presence of a chain transfer agent. In this manner, it is possible to improve sizing performance without reducing the hydrophobic level of copolymer and to suppress sensitization of printing plate such as PS plate by specifying the monomer composition ratio, using an azoic polymerization initiator, and specifying molecular weight of the copolymer.
摘要翻译：本发明的目的是提高胶版印刷中的施胶性能和抗平板性能，例如在用于涂布新闻纸的原纸的阳离子表面施胶剂中，作为解决该目的的方法，阳离子表面施胶剂通过季铵化通过聚合（a）20至40重量％的含有叔氨基的单体而获得的重均分子量范围为30,000至60,000的共聚物; （b）10〜80重量％的（甲基）丙烯酸的C 4〜C 18烷基酯; 和（c）0〜70重量％的苯乙烯或其衍生物，在链转移剂存在下使用偶氮聚合引发剂。以这种方式，可以在不降低共聚物的疏水性水平的情况下提高施胶性能，并且通过使用偶氮聚合引发剂指定单体组成比例和确定共聚物的分子量来抑制印刷板如PS板的敏化。
