FIELD: chemical or physical processes.
SUBSTANCE: invention relates to use of an aqueous polymer dispersion as a water retention modifier in a coloring coating. Aqueous dispersion is characterized by a viscosity value of 1–150 mPa·s with content of 40 wt % of solid substances and contains polymer particles with particle size D50 in range of 45–85 nm. Dispersion is obtained by free-radical emulsion copolymerisation of at least monomer (a) and monomer (b), where monomer (a) is at least one optionally substituted styrene, and monomer (b) is at least one C1-C4 alkyl (meth) acrylate, in a reaction mixture containing split starch, which has average molecular weight Mn 100–990 g/mol.
EFFECT: technical result is providing static retention of water coloring coating without increasing viscosity of coloring coating.
