Abstract: A toner process comprised of a first heating of a mixture of an acicular magnetite dispersion, a colorant dispersion, a wax dispersion, and a core latex comprised of a first latex containing a vinyl crystalline polyester resin substantially free of crosslinking, and wherein said polyester is substantially dissolved in a vinyl monomer and polymerized to provide said first core latex resin, and which mixture contains a second crosslinked resin containing latex wherein said heating is accomplished in the presence of a coagulant to provide aggregates; adding a shell latex comprised of a polymer substantially free of crosslinking, and further heating said aggregates to provide coalesced toner particles, and wherein said further heating is at a higher temperature than said first heating.

Abstract: A toner composition is provider including a branched amorphous polyester resin and a crystalline polyester resin, wherein the toner possesses rheological properties yielding desired characteristics.

Abstract: A process for preparing toner particles and compositions adapted for use in preparing toners that comprise a blend of a first polyester resin with a second sharp melting polyester resin. The process includes forming an emulsion resin comprising a branched polyester resin, a crystalline polyester resin, a colorant, and optionally a wax. The resin mixture is aggregated using an aggregating agent, such as a zinc acetate solution, to form an aggregate mixture. The aggregate mixture is then coalesced at a temperature of from about 5 to about 20° C. above the Tg of the emulsion resin to produce the resultant toner particles.

Abstract: A toner containing a mixture of a sulfopolyester resin, a colorant and an alkyl amide.
