摘要:
Included is an emulsion aggregation toner formulation having at least one latex and a combination of at least two waxes, wherein one wax is a synthetic wax, and another wax is a natural wax, and further including a developer containing a carrier and the just-described toner.
摘要:
A system, method and device for measuring toner performance by randomly applying a toner sample having toner particles to a substrate, and positioning the substrate such that a force may be applied to individual particles of the measuring toner. A rolling resistance or rotation of the individual particles of the measuring toner is measured. The measurements may be analyzed to determine adhesion and distribution properties of individual toner particles of the measuring toner sample.
摘要:
A toner having charge control agents which impart excellent triboelectric charging characteristics. In embodiments, the charge control agents include copolymers formed by an emulsion polymerization process.
摘要:
The present disclosure provides toners and methods for their production. In embodiments, the toner may include a core/shell configuration, with a non-crosslinked resin and a crosslinked resin in the core, with a second non-crosslinked resin in the shell, pigment/pigments and a wax possessing both branched and linear carbons.
摘要:
Disclosed are toner compositions comprised of a polymer, an optional colorant, and an UV light curable oligomer. Also disclosed are methods for producing a UV curable toner compositions, the toner compositions produced thereby, and methods of utilizing the UV curable toner compositions in various painting applications.
摘要:
A process for the preparation of toner involving (i) aggregating a colorant dispersion containing a suitable surfactant with a latex emulsion containing an anionic surfactant, a nonionic surfactant, and a water miscible chain transfer agent, or a nonionic surfactant with chain transfer characteristics to form toner sized aggregates; (ii) coalescing or fusing said aggregates; and optionally (iii) isolating, washing, and drying the resulting toner.
摘要:
Toners are described which include one or more copolymers combined with colorant particles or primary toner particles. Processes for preparing the toners are also disclosed.
摘要:
A process including: treating a mixture comprising an aqueous dispersion of toner particles and a first solution of a water soluble alkyl carboxylate metal salt with a second solution of a water soluble metal salt.
摘要:
A layered particle for use in forming toner may be formed by forming a core region; polymerizing in the presence of the core region at least one monomer feed to form at least one intermediate layer on the core region; and polymerizing in the presence of the core region with at least one intermediate layer thereon a final monomer feed. In the process, each monomer feed is different from the previous monomer feed so as to form different polymer layers.
摘要:
A process for the preparation of a latex comprising the polymerization of monomer in the presence of a chain transfer component, an initiator, a diphenyloxide disulfonate, and an optional nonionic surfactant.
