A process for preparing a dispersion dyed color toner for developing latent electrostatic images includes dyeing a particulate polymer resin in organic medium in which the resin is not soluble. The resin is a functionalized resin having sites suitable for interacting with functionalized dyes have corresponding functionality. The functionalized dye is applied to the resin particles typically with a dyeing aid, or surfactant. The particle size distribution of the polymer resin is substantially unchanged during the toner preparation process.
