摘要:
A carrier comprised of a core and a polymer generated from a mixture of two latexes, and wherein the first latex enables a polymer with a high molecular weight, and the second latex enables a polymer with a low molecular weight, and wherein high represents a weight average molecular weight of from about 1,000,000 to about 8,000,000, and said low represents a weight average molecular weight of from about 500,000 to about 750,000.
摘要:
Toner particles include a shell and a core, wherein the shell includes charge control agent-treated spacer particles that cause protrusions from the toner particle surface.
摘要:
A toner having charge control agents which impart excellent triboelectric charging characteristics. In embodiments, the toner particles are washed with a solution containing metal ions that impart desirable charging characteristics to the toner particles.
摘要:
Disclosed is a toner composition comprising: (a) a resin; and (b) a colorant which comprises: (1) Pigment Red 269; (2) Pigment Red 185; and (3) Pigment Red 122.
摘要:
The present disclosure provides processes for reducing the particle size of latex resins and toners produced with such resins. In embodiments, a gel latex may be formed as a seed particle and then utilized to form latex resins and toner particles. In accordance with the present disclosure, one may be able to utilize materials for the production of latex resins and toners which may otherwise produce particles that are too large in the absence of the gel latex.
摘要:
A toner having a core with at least one resin and at least one colorant, and having on a surface thereof, an additive package including fluorinated polymer particles, and a method of forming toner particles having surface particles attached thereto, wherein the surface particles include fluorinated polymer particles, and the method includes aggregating a material with at least one resin and at least one colorant to produce toner particles, following aggregation, forming a mixture of the surface particles and the toner particles, and subjecting the mixture to a temperature above the glass transition temperature of the toner particles to coalesce the toner particles, whereby the surface particles become at least partially embedded within the surface of the toner particles.
摘要:
A toner includes particles of a resin, an optional colorant, a first wax and a second wax, where the toner particles are prepared by an emulsion aggregation process. Additional waxes can also be added for different properties.
摘要:
The present disclosure provides methods for incorporating a dye into latex particles via a supercritical fluid microencapsulation technique, in order to achieve improved dispersion of a colorant in the latex and an increase in color gamut.
摘要:
A process for preparing a latex includes polymerizing at least one monomer in the presence of an initiator to form a polymer emulsion; and adding an odor-scavenging bismuth compound to the formed polymer emulsion.
摘要:
A toner is described containing low melt wax and having a core and shell, which toner exhibits improved fusing performance as compared to a toner produced with a high melt wax in the core; having a core resin with a Tg equal to or lower than that of the shell resin; or both.
