Abstract

Disclosed are encapsulated toners comprised of a core containing a polymer, such as a styrene methacrylate, magnetite, and surface treated particles, which core is encapsulated in a polymeric shell. More specifically, the encapsulted toner is comprised of a core containing a styrene butylmethacrylate copolymer, a magnetite, preferably Mapico Black, and surface treated iron particles including those particles available from Bayer as AC5130M, 0.4 micron, and wherein the core components are enca sulated in a polymeric shell obtained by interfacial polymerization,

Toner compositions obtained by a process which comprises forming an organic phase comprised of polymer and solvent, such as toluene, xylene, or halogenated components including trichloroethylene, forming an aqueous phase comprised of water and pigment, and flushing the pigment into the organic phase followed by dilution. In another embodiment, the toner is obtained by a process which comprises forming an organic phase by the mixing of a polymer and a solvent, forming an aqueous phase cake by...
