摘要:
A toner composition having toner particles comprising a gel latex, a high Tg latex, a wax, and a colorant. The gel latex is present in an amount of from about 3 weight percent to about 30 weight percent of the toner composition, the high Tg latex is present in an amount of from about 50 weight percent to about 95 weight percent of the toner composition, the wax is present in an amount of from about 2 weight percent to about 40 weight percent of the toner composition, and the colorant is present in an amount of from about 1 weight percent to about 25 weight percent of the toner composition.

摘要:
A method of making toner particles, including mixing at least one emulsion of at least one resin, a colorant, an optional wax, and optional additives to form a slurry; heating the slurry to form aggregated particles in the slurry; freezing aggregation of the particles by adjusting the pH; and heating the aggregated particles in the slurry to coalesce the particles into toner particles.

摘要:
The toner described herein contains toner particles containing polymer, colorant and cross-linked polymer. The cross-linked polymer is incorporated at least in the shell of the toner particles. Incorporating cross-linked polymer in the shell of the toner particles provide bumps in the surface of the toner particles. These bumps can behave as spacers. Such toner can be formed by aggregating at least polymer particles and colorant particles to form core particles; aggregating at least cross-linked polymer particles to the surface of the core particles; and coalescing the resulting particles to form toner particles.
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 toner composition that includes a resin substantially free of cross linking, a cross linked resin, a polyester resin as a crystalline polyester resin, and a colorant.

摘要:
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.
