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&#xb0; C. above the Tof the emulsion resin to produce the resultant toner particles.

Low melt toners and processes thereof

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.

Toner compositions and processes for making same

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.

Toner processes

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

Toner composition

A dispersion comprised of a wax and a hydrophilic polyester stabilizer.

Wax dispersions and process thereof

A toner comprised of a branched amorphous resin, a crystalline resin, and a colorant.

Toner compositions and processes thereof

A process comprising applying a toner security mark on a document generated by xerographic means, and which mark possesses white glossy characteristics, and wherein said toner is comprised of a waterborne polymer resin and a colorant, and optionally a second security mark generated by a toner comprised of a waterborne polymer resin and a UV fluorescent component.

Document security processes

An ink composition comprised of (1) a carbamate or thiourea each with a melting point of from about 60.degree. C. to about 120.degree. C. and an acoustic-loss value of from about 25 to about 80 dB/mm, (2) an alcohol compound with melting point of about 25.degree. C. to about 90.degree. C. and with an acoustic-loss value of from about 5 to about 40 dB/mm, (3) a lightfastness component, (5) an antioxidant, and (6) a colorant.

Inks

An ink composition comprised of a colorant and a phase change vehicle derived from the reaction product of a resin containing at least one furan moiety and at least one maleimide moiety, and wherein said ink possesses a viscosity of from about 1 centipoise to about 20 centipoise at a temperature of from about 100.degree. C. to about 180.degree. C.

Phase change ink compositions

An ink composition comprised of a colorant and a reversible crosslinked component vehicle obtained from the reaction product of an anhydride and an organoamine, and which ink possesses a viscosity of from about 1 centipoise to about 25 centipoise at a temperature of from about 125.degree. C. to about 185.degree. C.
