摘要:
Toner particles are provided which may, in embodiments, include a core and a shell. In embodiments, charge control agents may be co-emulsified with a resin utilized to form a shell. The shell may prevent a crystalline resin in the core from migrating to the toner surface. Inclusion of the charge control agent in the shell itself may provide the resulting toner particles with desirable charge characteristics and sensitivity to relative humidity.
摘要:
Environmentally friendly toner particles are provided which may, in embodiments, include a bio-based amorphous polyester resin, optionally in combination with another amorphous resin and/or a crystalline resin. Toner particles may, in embodiments, have a core-shell configuration, with the shell formed of the bio-based amorphous polyester resin, the amorphous polyester resin, the crystalline polyester resin, or combinations thereof.
摘要:
Toner particles are provided which may, in embodiments, include a high molecular weight branched or cross-linked polyester to decrease image gloss and to increase toner elasticity to prevent surface additives impaction. In embodiments, the toner particles may have a core-shell configuration, with the high molecular weight polyester in the core, the shell, or both.
摘要:
Polymer particles comprising a cross-linked polymer core and a linear non-cross-linked polymer shell may be formed by emulsion polymerization. The polymer particles may be used in forming toner.
摘要:
Pyrophoric nanoparticles and methods of producing the same are provided herein. An exemplary method of producing pyrophoric nanoparticles can include providing a first aqueous solution comprising at least one metal salt and an aliphatic polyether; providing a second solution comprising a metal hydride reducing agent; continuously combining the first and second solutions to produce nanoparticles in a liquid phase; separating the nanoparticles from the liquid phase; and drying the nanoparticles to form pyrophoric nanoparticles. The pyrophoric nanoparticles can have a diameter ranging from about 1 nm to about 50 nm.
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.
