Abstract: Process for improving the printability of paper by a single- or two-sided application of aqueous coating materials consisting of a) 100 parts by weight of a finely dispersed pigment b) 5 to 70 parts by weight (based on solids) of a cationic aqueous polymer dispersion of a paper size and c) 0.01 to 10 parts by weight of a surfactant which interferes with the formation of the surface sizing and/or of a polymeric dispersant to the surface of the paper in a quantity of 0.5 to 4 g/m and drying the coated paper.

Abstract: Mixtures of paper sizing agents are produced by mixing an aqueous suspension of a hydrolyzed cationic starch with fine particle aqueous polymer dispersions which constitute a paper sizing agent, and by emulsifying C14-C22-alkyl diketens in said mixture at temperatures of at least 70 DEG C. The mixtures are used for paper beater and surface sizing.
