摘要： A chemically prepared toner composition made up of a toner particle with a core having a first polymer binder, a monomer free radical polymerization formed core shell styrene acrylic latex having a liquid gel core, a pigment, a wax, and a shell formed around the core including a second polymer binder and method to make the same is disclosed. An optional borax coupling agent can be placed between the outer surface of the core and the shell to assist in the binding of the polymer found in the shell onto the surface of the toner core containing the first polymer.

摘要： The present disclosure relates to a chemically prepared toner composition including a toner particle having a core including a first polymer binder, an styrene acrylate encapsulated crystalline polyester latex, a pigment, and a shell formed around the core including a second polymer binder and method to make the same. The disclosed method of preparing the toner results in a change in the distribution of the components of the toner particle wherein the lower molecular weight resins, the pigment and the wax are located away from the surface of the toner particle and the pigment is clinging to the edge of the wax domain.

摘要： A chemically prepared toner composition according to one example embodiment includes a core including at least one polymer binder, a colorant and a release agent; a shell that is formed around the core and includes a third polymer binder; and a borax coupling agent between the core and the shell. The binder for the shell is a styrene acrylic polyester copolymer having a glass transition temperature (Tg) between 55° C. to 65° C., a melt temperature (Tm) between 100° C. to 130° C., a peak molecular weight of about 12,000 and acid value from 10-28.

摘要： A method for producing core shell toner for electrophotography according to one embodiment, includes surface treating the outer surface of a core shell toner particle with a alkoxysilane hydrocarbon or combination of different alkoxysilane hydrocarbons using a hydrolytic deposition process after the core shell toner particle is fully formed. This method results in the bonding of the alkoxysilane hydrocarbon or combination of different alkoxysilane hydrocarbons to the outer surface of the core shell toner particle. In an alternative method, the outer surface of the toner is surface treated with the alkoxysilane hydrocarbon solution and then fused to form toner particles. The alkoxysilane hydrocarbon surface treated core shell toner also can be mixed with magnetic carrier beads to form a developer mix to be used in a dual component development electrophotographic printer.

This successful alkoxysilane hydrocarbon surface treatment on the outer surface of the toner particle results in attaining a desirable charge stability in hot and humid environments and ultimately improving the quality of the toner, especially by reducing toner dusting, toner fuming and ultra-fine particles generation.

摘要： A chemically prepared multilayered toner composition, according to one example embodiment, includes a core having a first polymer binder, a second polymer binder, a colorant, and a release agent. A first layer is formed around the core wherein the first layer includes the same second polymer binder that is in the toner core. A second layer is formed on the surface of the first layer, wherein the second layer includes a third polymer binder. A borax coupling agent is between the first and second layers. In an embodiment the ratio of the second polymer in the core to second polymer in the first layer is about 50:50. The second layer can also be referred to as a shell that is formed over the toner particle having a center core, first layer and borax coupling agent. In another embodiment, the core does not contain a second polymer binder.
