Printability of paper

摘要

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.
