FIELD: chemistry.
SUBSTANCE: invention relates to aqueous polyacrylate dispersions for coating. The dispersion contains a hydrophobic polymerisation product with hydroxyl functional groups, a hydrophilic polymerisation product with hydroxyl functional groups and contains, as a solvent, cosolvents consisting of at least one hydrophobic, water-immiscible hydrocarbon whose initial boiling point (according to ASTM D86-05) ranges from 170°C to 250°C and final boiling point (according to ASTM D86-05) ranges from 200°C to 280°C.
EFFECT: invention is suitable for producing aqueous two-component polyurethane lacquer with considerably larger thickness of the bubble-free layer.
