Abstract

The present invention describes the use of finely divided dye-containing polymers PD in the form of an aqueous polymer dispersion or a polymer powder obtainable therefrom, the polymer matrix of which comprises at least one organic dye D in homogeneously dispersed form, as color-imparting constituent in cosmetic compositions. The present invention also describes cosmetic compositions which comprise a color-containing polymer in an amount of from 0.1 to 50% by weight, based on the total weight of the cosmetic composition, and additives customary for cosmetic compositions.
