FIELD: chemistry.
SUBSTANCE: invention relates to the use of an aqueous polymer dispersion comprising: (a) at least two monomers M1 with a glass transition temperature ≥25°C, (b) at least two monomers M2 with a glass transition temperature of <25°C, and optionally additional monomers M3, as a binder in coating agents for improving colour retention.
EFFECT: disclosed dispersion significantly improves colour retention.
