FIELD: improvement of glazed piper and board printing properties and coverability.
SUBSTANCE: claimed method includes addition to fibrous starting material polysaccharide and at least dispersed polymer, containing hydrophobic monomers, as hydrophobic agent. As polysaccharide cationic, non-ionic and/or anionic starch are used. Styrene, butadiene, vinylacetate, acrylonitrile, and/or acrylates, preferably styrene, butadiene, and/or acrylates are used to produce polymer dispersion. Polymer dispersion is obtained by emulsion polymerization. Mixture added to starting fibrous material for paper production contains polysaccharide and at least dispersed polymer, containing hydrophobic monomers, as hydrophobic agent.
EFFECT: paper and board with improved printing characteristics.
