    Abstract: The printability of paper is improved by applying an aqueous coating agent consisting of a) 100 parts by weight of a finely divided pigment, b) from 5 to 70 parts by weight, based on solids, of a cationic aqueous polymer dispersion of a paper size and c) from 0.01 to 10 parts by weight of a surfactant which interferes with the formation of the surface size and/ or of a polymeric dispersant in an amount of from 0.5 to 4 g/m2 to one or both surfaces of the paper and drying the coated paper.

    Abstract: The printability of paper is improved by appln. to 1 or both sides, at a rate of 0.5-4 g/square m, of a compsn. contg. (a) 100 pts. wt. of finely divided pigment, (b) 5-70 pts., as polymer, of a cationic aq. polymer dispersion of a paper size, where the Tg of the polymer is 5-80 deg C, and (c) 0.01-10 pts. of a surface-active cpd. and/or a polymeric dispersant which prevents surface sizing, followed by drying of the paper.
