Patent application numberDescriptionPublished
20080233509SPHERICAL SILICA CORE-SHELL PARTICLES - A process of preparing spherical nano-sized core/shell silica particles, including providing a latex polymer dispersion comprising particles of a liquid dispersible starting polymer in a dispersion liquid, adding at least one functionalized monomer to the latex polymer dispersion and polymerizing the at least one functionalized monomer on the particles, and growing an outer silicate shell on the particles through addition and reaction of at least one silane monomer.09-25-2008
20090123864Ultra Low Melt Toners Comprised of Crystalline Resins - A toner having an amorphous resin, a crystalline resin, and a colorant, wherein the crystalline resin has a melting temperature of at least 70° C. and a recrystallization point of at least 47° C. exhibits improved document offset properties and improved heat cohesion. Annealing the toner further improves the heat cohesion and morphology of the toner.05-14-2009
20090280429POLYESTER SYNTHESIS - The present disclosure provides for enzymatic polymerization to produce polyester resins suitable for use in manufacturing toners.11-12-2009
20090305159TONER COMPOSITIONS - Toner particles are provided which may, in embodiments, include a core possessing at least one polyester resin in combination with a colorant, optional wax, and optional other additives, and a shell over the core including a high molecular weight amorphous polyester resin. The high molecular weight amorphous polyester resin in the shell may prevent any crystalline polyester resin in the core from migrating to the toner surface.12-10-2009
20100055593TONER COMPOSITIONS - Toner particles are provided which may, in embodiments, include a core and a shell, one or both of which may include a polyester gel. The gel in the shell and/or core may prevent a crystalline resin in the core from migrating to the toner surface.03-04-2010
20100122642INKS INCLUDING CARBON NANOTUBES DISPERSED IN A POLYMER MATRIX - An ink having a polymer matrix including carbon nanotubes dispersed in a polymer; optionally one or more colorants; and optionally one or more waxes.05-20-2010
20100124713TONERS INCLUDING CARBON NANOTUBES DISPERSED IN A POLYMER MATRIX - A toner comprising: a polymer matrix comprising carbon nanotubes dispersed in a polymer; optionally one or more colorants; and optionally one or more waxes.05-20-2010
20100136472TONER COMPOSITIONS - Toner particles are provided which may, in embodiments, include a high molecular weight branched or cross-linked polyester to decrease image gloss and to increase toner elasticity to prevent surface additives impaction. In embodiments, the toner particles may have a core-shell configuration, with the high molecular weight polyester in the core, the shell, or both.06-03-2010
20100159376TONERS CONTAINING POLYHEDRAL OLIGOMERIC SILSESQUIOXANES - Disclosed is a toner composition comprising toner particles which comprise (a) a resin having chemically bonded thereto a polyhedral oligomeric silsesquioxane, (b) and an optional colorant.06-24-2010
