Abstract: PROBLEM TO BE SOLVED: To obtain a constituent readily mixable in a cosmetic composition and suitable for imparting a color to the cosmetic composition having advantages of a pigment, the so-called chemically inert behavior toward other constituents of the cosmetic composition and low solubility in water. SOLUTION: This fine dye-containing polymer PD comprises a polymer substrate containing at least one organic dye in the uniformly dispersed form.

Abstract: PROBLEM TO BE SOLVED: To provide a colorant-containing aqueous polymer dispersion containing no anionic emulsifying agent, its manufacturing method, and a cosmetic composition using the same. SOLUTION: The colorant-containing aqueous polymer dispersion comprises (a) (i) a polymer matrix to be prepared from an ethylenically unsaturated monomer M and (ii) colorant-containing polymer particles which are uniformly dispersed in the above polymer matrix and contain at least one organic colorant C to be selected from a dye, an UV absorber, and a fluorescent brightener and, simultaneously, have an average particle diameter d50 of
