The present disclosure provides polymeric composition for use with toner particles. The polymeric composition of the present disclosure includes a silicone-polyether copolymer and a polymeric additive, wherein the silicone-polyether copolymer comprising a polysiloxane unit and a polyether unit, and the polymeric additive comprising a copolymer possessing at least one monomer having a high carbon to oxygen ratio, a monomer having more than one vinyl group, and at least one amine-functional monomer. The present disclosure also provides method of making thereof.

Toner compositions and surface polymeric additives

A method of synthesizing a branched polyester resin. Particularly, the method includes an alkoxylation reaction that includes reacting a monomer bisphenol A with a cyclic alkylene carbonate.

Method of making branched polyester resin

Disclosed is a carrier suitable for use with an electrophotographic developer and an electrophotographic developer containing the carrier. In particular, the carrier is powder coated and comprises a copolymer of cyclohexylmethacrylate and dimethylaminoethylmethacrylate.

Carrier and developer

Unsaturated polyester resins and processes for making the same are disclosed herein. In particular, the process for making the resin provides resins with improved properties. The unsaturated polyester resins have substantially reduced free fumaric acid as compared to that made from conventional processes. The toner resins are used to prepare toner compositions that have improved performance.

Toner resins and processes for making the same

Amorphous polyester resins and processes for making the same are disclosed herein. In particular, the process for making the resin provides resins with improved properties. The amorphous polyester resins have substantially reduced free fumaric acid as compared to that made from conventional processes. The toner resins are used to prepare toner compositions the have improved performance.

A pigment particle coated with at least one of a resin and a charge control surface additive, wherein the pigment particle is a pearlescent or metallic pigment. The pigment adds pearlescent effects and is of a size and charge as to be used as a toner material in electrostatographic or xerographic image formation.

Resin-coated pearlescent or metallic pigment for special effect images

Pigment particles with at least one metal oxide surface additive, wherein the at least one metal oxide surface additive is a metal oxide particle covalently bonded with at least one polycondensation polymer, wherein the pigment particle is a pearlescent or metallic pigment.

Grafting functionalized pearlescent or metallic pigment onto polyester polymers for special effect images

Toner compositions include a non cross linked resin; a cross linked resin or gel; a wax; and a colorant. Processes for preparing a toner include mixing a non-cross linked resin and a cross-linked resin or gel in the presence of a wax, a colorant, and a coagulant to provide toner size aggregates; adding additional non-cross linked latex to the formed aggregates thereby providing a shell over the formed aggregates; heating the shell covered aggregates to form toner; and, optionally, isolating the toner.

Toner compositions

Disclosed herein are toner particles generated by emulsion/aggregation processes. The processes are conducted under conditions that shorten the time for coalescence and post-formation washing, thereby increasing efficiency of the processes as compared to conventional processes.

Toner processes

Toner particles comprise resin, wax and optionally colorants, and the wax is substantially excluded from the interior core of the toner particles. Processes for preparing such toner particles comprise providing an aqueous dispersion of resin particles and optionally colorants, mixing the aqueous dispersion in presence of a coagulant, aggregating to form particles, coalescing to form fused particles, and removing the fused particles from the aqueous dispersion. Wax dispersions can be added either after mixing or during aggregation, so that wax is excluded from the core of the toner particles.

Toner particles and methods of preparing the same

Carrier comprised of a mixture of a first carrier and a second carrier, and wherein the first carrier is comprised of a steel core and the second carrier is comprised of a magnetite.
