Abstract (en)
[origin: WO2006058711A2] The invention relates to a paper sizing agent comprising a stable aqueous dispersion of a reactive sizing agent, 5 to 100 % by weight, with regard to the reactive sizing agent, of an essentially linear nitrogen-containing polymer with at least 3 mmol/g of basic nitrogen atoms, and 1 to 50 % by weight of cationic starch with a degree of substitution of at least 0.05. The paper sizing agent exhibits a good sizing effect and has a constant viscosity.
