摘要:
A process for the preparation of polymer compositions which comprises mixing a conductive component with an anionic polymeric latex containing a polymer; adding a cationic surfactant, or flocculant whereby the aggregation of the latex particles and the conductive component particles results; subsequently adding colloidal stabilizer, followed by the addition of a base to obtain a pH of from about 7 to about 12; heating above about the polymer glass transition temperature thereby enabling the severage, or breakage of the formed aggregated particles; further heating above about the polymer glass transition temperature enabling the coalescence of the polymer and conductive component particles; and optionally washing and drying the resulting coalesced product.
摘要:
A process for preparing silane metal oxides comprising reacting a metal oxide with an amine compound to form an amine metal oxide intermediate, and subsequently reacting said intermediate with a halosilane.
摘要:
A colored magnetic encapsulated toner composition comprised of a core comprised of a polymer binder, magnetic metal particles, whitener, color pigment, dye or mixtures thereof, and which core is encapsulated in a polymeric shell, and wherein the toner surface comprises an optional conductive metal oxide, or metal oxides and an optional release additive, or additives.
摘要:
Processes for producing emulsion aggregation toners are provided. In embodiments, methods of the present disclosure may be utilized to produce toners suitable for low melt applications, including use in flexible packaging applications, where low pile height is desired for low cost and flexibility. In embodiments, the EA toners may include small particles having a shell with a high amount of resin, which optimizes the charging characteristics of the toner.
摘要:
The present disclosure provides polymeric additives for use with toner particles. The polymeric additive of the present disclosure includes a copolymer possessing at least one monomer having a high carbon to oxygen ratio, a monomer having more than one vinyl group, and at least one amine-functional monomer. Toners possessing this polymeric additive exhibit excellent stability with respect to relative humidity and excellent charging characteristics.

A phase change magnetic ink including a phase change ink carrier; an optional colorant; an optional dispersant; an optional synergist; an optional antioxidant; and a carbon coated magnetic nanoparticle comprising a magnetic core and a carbon shell disposed thereover.
摘要:
A light-cyan solid ink including an ink vehicle and a colorant. The colorant includes a cyan colorant, a hue-adjusting colorant that absorbs light having a wavelength of from about 500 to about 600 nm, and an optional shade-adjusting colorant that absorbs light having a wavelength of from about 400 to about 500 nm.
摘要:
A color image forming machine is provided having a plurality of xerographic marking engines, each forming associated color separations that are combined to produce a color print image. Each marking engine includes a dual replenisher assembly having first and second reservoirs containing respective toners of different gloss levels. The reservoirs each include one or more augers separately and independently controlled for dispensing the respective toners into a developer to continuously vary the gloss level of the toner in the developer.
摘要:
The present disclosure provides carriers for use with toner compositions. In embodiments, a carrier may include a core having a polymeric coating on at least a portion thereof. The polymer coating possesses cation binding groups. Processes for coating such carriers with the polymeric coatings are also provided.
