摘要： A color toner composition includes dyed toner resin particles having a volume average diameter in the range of from about 2 microns to about 10 microns with a size distribution span value of less than 1.0. Preferred particles are characterized further by a micro-serrated surface exhibiting a roughness index value larger than about 1.2. The resin toner particles are prepared utilizing a dye-mediating co-solvent which facilitates transfer from a dispersion medium to the resin particles.

摘要： 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.
