ABSTRACT:
The present invention relates to amphipathic copolymeric binder particles chemically grown in a substantially nonaqueous liquid carrier to form an organosol. The invention also pertains to dry particulate electrographic toners incorporating an organosol comprising an amphipathic copolymer wherein the amphipathic copolymer incorporates one or more S portions and one or more D portions. Methods of making dry electrophotographic toner particles, and methods of electrographically forming an image on a substrate using these toners, are also described. Preferably, fluidized drying techniques are used to form the dry toner particles from the organosol.
