Abstract
The present invention provides the use of aqueous polymer dispersions comprising (a) at least two monomers M1 having a glass transition temperature≧25° C., (b) at least two monomers M2 having a glass transition temperature<25° C., and also further monomers M3, as binders in coating materials for improving the shade stability (color retention).
