    摘要: A process for the preparation of pigmented toner compositions comprising: a) forming at a first temperature, a first melt mixture comprised of a partially crosslinked thermoplastic resin, pigment, optionally a wax, and optional additives, wherein the partially crosslinked thermoplastic resin is comprised of a mixture of crosslinked resin macrogel particles, crosslinked resin microgel particles, and uncrosslinked resin; and b) melt mixing at a second temperature, the first melt mixture to form a second mixture, wherein the macrogel particles are partially converted into microgel particles, and wherein the second temperature is less than or equal to the first temperature.
