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:
Toner compositions comprising toner particles including an amorphous resin, a crystalline resin and a charge control agent. The toner compositions having the charge control agent exhibit improved charge performance in the C-zone and the A-zone, and improved RH sensitivity.
摘要:
An emulsion aggregation toner composition includes toner particles including: an amorphous polyester resin; an optional crystalline resin; an optional colorant; an optional wax; an optional coagulant; and a polymeric or oligomeric hydroxy ketone photo initiator capable of initiating crosslinking of said polyester resin, wherein at least one of the amorphous polyester resin and the optional crystalline resin when present is unsaturated.
摘要:
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.

Disclosed is a toner composition comprising toner particles which comprise a resin, an optional colorant, and a polyhedral oligomeric silsesquioxane compound.
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.
