    • A process for making paper products is described in which sizing is effected by use of a hydrophobic cellulose-reactive sizing agent in combination with a promoter. As promoters water-insoluble bases are used which are formed by the reaction of saturated fatty acids, unsaturated fatty acids, hydroxy substituted fatty acids and/or mixtures thereof and alkanoldimaines and/or aliphatic polymaines. Further a corresponding paper sizing composition is described which comprises a hydrophobic cellulose-reactive sizing agent and such a promoter. The combination of hydrophobic celluulose-reactive sizing agent and promoter provides a synergistic effect so that for achieving the same sizing level a lower amount of hydrophobic cellulose-reactive sizing agent is required. Alternatively at the same concentration of the hydrophobic cellulose-reactive sizing agent a higher sizing level can be achieved.
    • 描述了制造纸制品的方法,其中通过使用疏水纤维素反应性施胶剂与促进剂组合来进行施胶。 作为助溶剂,使用通过饱和脂肪酸,不饱和脂肪酸,羟基取代的脂肪酸和/或其混合物和烷基酰亚胺和/或脂族多聚核苷酸的反应形成的不溶于水的碱。 此外,描述了相应的纸张施胶组合物,其包含疏水性纤维素反应性施胶剂和这种促进剂。 疏水纤维素糖反应性施胶剂和促进剂的组合提供了协同效应,使得为达到相同的施胶水平,需要较少量的疏水纤维素反应性施胶剂。 或者,在相同浓度的疏水性纤维素反应性施胶剂中,可以实现更高的施胶量。
