摘要:
Toners made by the emulsion aggregation process comprising an amorphous resin and a nucleated crystalline resin. Such toners demonstrate improved charging performance in the A-zone and the C-zone, improved heat cohesion and improved resistivity.
摘要:
A toner comprising toner particles, a polymer binder, at least one colorant and clay composites distributed in the polymer binder, wherein the clay composites comprise a polymer modified clay.
摘要:
A method for making toners to include clay composites. The clay composites are incorporated into emulsion of toner and used in making toner via emulsion aggregation. Such toners may have a core and/or a shell and the clay composites may be included with the core, the shell or both.
摘要:
Environmentally friendly toner particles are provided which may include a bio-based amorphous polyester resin, optionally in combination with another amorphous resin and/or a crystalline resin. Methods for providing these toners are also provided. In embodiments, the bio-based amorphous polyester resin includes a biologically derived diol, such as 2,3-butanediol.

摘要:
A toner process comprising the aggregation and coalescence of an amorphous polyester, a crystalline polyester and a colorant, and wherein the coalescence is conducted at a temperature that is about lower than the melting point temperature of the crystalline polyester.
摘要:
Processes for producing emulsion aggregation toners are provided. In embodiments, methods of the present disclosure may be utilized to produce toners suitable for low melt applications, including use in flexible packaging applications, where low pile height is desired for low cost and flexibility. In embodiments, the EA toners may include small particles having a shell with a high amount of resin, which optimizes the charging characteristics of the toner.

摘要:
A toner having an amorphous resin, a crystalline resin, and a colorant, wherein the crystalline resin has a melting temperature of at least 70° C. and a recrystallization point of at least 47° C. exhibits improved document offset properties and improved heat cohesion. Annealing the toner further improves the heat cohesion and morphology of the toner.
