The work is aimed at control of physical and chemical properties of paper by surface application of water based polymer dispersions. The polarity and specific charge density as well as hydrophobic effect of alkylketen-dimer, styrene-acrylate copolymer, styrene-butadiene latex, copolymers of styrene and dimethyl aminopropylamine maleimide and styrene-acrylic ester on printing properties of modelled papers was studied. All papers were printed with thermal inkjet printer using dye and pigmented water-based inks. Print quality was evaluated in terms of optical density, water fastness and print sharpness. The necessity to modify and to optimise sizing solutions in order to create a cationic and simultaneously sufficiently and adequately hydrophilic paper surface is emphasized.
