Abstract
The invention relates to a composition for modifying rheology of coating colour and its use. The composition comprises an aqueous polymer dispersion, comprising a copolymer of monomer (a), which is at least one optionally substituted styrene, and monomer (b), which is at least one C1-C4-alkyl (meth)acrylate. The copolymer has a particle size D50<100 nm. Composition comprises also degraded starch having an average molecular weight Mn<1000 g/mol.
