PAPER SURFACE TREATMENT WITH COMPOSITION TO INCREASE PRINTABILITY; AQUEOUS PAPER COATING COMPOSITION

摘要

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<2> and drying the coated paper.
