A resin kneaded product containing at least a binder resin and a colorant ... 12/21/06 - 20060286480 - Method of producing toner, and toner Spherical-shaped liquid droplets are made by dispersing oil phase containing: a resin with an acid group, a first hydrophobic solvent effecting dissolution of the resin, a colorant, and a charge control agent which is positively charged in an aqueous dispersion medium in the presence of a base; and the liquid ... 11/09/06 - 20060251985 - Toner composition comprising polyester toner particles encapsulating a wax and method of producing same The invention pertains, in part, to a toner composition that is suitable for developing latent electrostatic images and being comprised of substantially spherical polyester particles with a volume average diameter in the range of 2-10 microns and which contain a wax component in the interior. The invention also pertains to ... 10/26/06 - 20060240354 - Toner, method of preparing the toner and apparatus for preparing the toner A toner, a method of and an apparatus for preparing a permanently-charged electret toner, including discharging a solution or dispersion including a resin and a colorant through a nozzle vibrating at a constant frequency to form a droplet; applying a direct potential to an electrode facing the nozzle to positively ... 09/21/06 - 20060210909 - Method for producing a toner, and toner The object of the present invention is to provide a method for producing a toner which includes ejecting a toner composition fluid containing a toner composition which contains a toner and a colorant, from a nozzle vibrated at a constant frequency to make the toner composition fluid into droplets, and ... 06/01/06 - 20060115764 - Methods for washing and dewatering toner Methods include washing and de-watering toner particles using a horizontal filter press. ... 06/01/06 - 20060115763 - Method and device for processing powder A powder is de-aerated in a collector and then transferred to a chamber via a valve. The chamber may then be injected with a low-pressure air stream carrying an additive for mixing with the de-aerated powder. The mixing of the powder with the air and additive stream may occur in ... 04/13/06 - 20060078817 - Toner processes and compositions thereof The invention relates to a process for the preparation of a dry toner powder from an aqueous pigment concentrate dispersion by blending at least an aqueous-based pigment concentrate dispersion and a resin compound to produce a paste; charging the paste to an extruder to generate a hot melt extrusion; dispersing ... 01/05/06 - 20060003251 - Drying process for toner particles useful in electrography The present invention relates to methods of drying and recovering toner particles from a liquid carrier. The methods are very effective to generate discrete, substantially non-agglomerated dry toner particles in a manner that preserves the particle size and particle distribution of the wet particles. The resultant dried toner particles free-flowing ... 01/05/06 - 20060003250 - Extrusion drying process for toner particles useful in electrography The present invention relates to methods of drying and recovering toner particles from a liquid carrier. The methods are very effective to generate discrete, substantially non-agglomerated dry toner particles in a manner that preserves the particle size and particle distribution of the wet particles. The resultant dried toner particles free-flowing ... 12/08/05 - 20050271969 - Method of preparing toner A method of preparing a toner includes: adding a first external additive having an average primary particle diameter of between about 30 nm and 200 nm to toner particles including a binder resin and a colorant and stirring the first external additive with the toner particles to form a first ... 11/17/05 - 20050255401 - Closed air circulation toner rounding Toner is rounded by vigorously mixing less than about 5 percent by weight of particulate silica to the total weight of a starting toner in a closed, recirculating air system. The starting toner contains at least about 4.5 percent by weight of the starting toner of a wax and additionally ... 11/03/05 - 20050244738 - Process for preparing colored toner particles A process for the preparation of colored polymeric toner particles includes: forming an organic phase by dissolving an organic polymer and, optionally, one or more additives in a water-immiscible organic solvent; forming a dispersion by combining the organic phase with an aqueous phase comprising a particulate stabilizer, a colorant, and, ... 09/15/05 - 20050202336 - Method of manufacturing a toner A method of manufacturing a toner for developing static charges in an aqueous system is provided which includes preparation step for a resin kneaded product, preparation step for the aqueous dispersion of a less water-soluble alkaline earth metal salt, preparation step for synthetic resin particles, removal step for the less ... ### FreshPatents.com Support |
