| 430137220 | Making a liquid toner or concentrate | 6 |
| 20090155712 | CURABLE POLYESTER LATEX MADE BY PHASE INVERSION EMULSIFICATION - A process for preparing a curable polyester based emulsion is provided in embodiments, containing one or more unsaturated polyesters and one or more photoinitiators obtained by a phase inversion process, in which the particle size and particle size distribution is controlled by process parameters, such as solvent, solvent ratio, neutralization ratio of the resin and temperature. | 06-18-2009 |
| 20110236822 | METHOD OF TREATING SEASONED DEVELOPER SOLUTION - Seasoned lithographic printing plate developer solutions are treated with a hypochlorite to decompose infrared radiation-sensitive cyanine dyes that are released from lithographic elements during alkaline development. The hypochlorite is useful to decompose both suspended and soluble forms of the cyanine dyes so they can be more safely discharged to the environment in the seasoned developer solution. This treatment avoids expensive filtration equipment and incineration for handling seasoned developer solutions before they are discharged to the environment. | 09-29-2011 |
| 20110269069 | METHOD OF CHARGING TONER PARTICLES - A method of charging toner particles in a liquid toner includes mixing the toner with an acid, and mixing the toner with a base that reacts with the acid to charge the toner particles. The base is added first and the acid subsequently to charge the toner particles with a positive charge. | 11-03-2011 |
| 20130288177 | INKS FOR LIQUID ELECTROPHOTOGRAPHY - A method of manufacturing a liquid electrophotographic ink includes: mixing a first portion of a carrier fluid and a resin to form a resin mixture; heating the resin mixture until the resin has melted; cooling the resin mixture to form a resin cake, followed by pulverizing the resin cake to form a resin powder; and mix the resin powder with a pigment and a second portion of carrier fluid in a microfluidizer to form a concentrating ink containing composite particles. An alternate method of manufacturing a liquid electrophotographic ink includes: mixing a pigment with a resin powder; and microfluidizing the mixture together with a carrier fluid in a microfluidizer in a number of passes to form a concentrated ink containing composite particles. | 10-31-2013 |
| 20140199627 | METHOD AND APPARATUS FOR CONCENTRATING AN INK FOR AN ELECTROSTATIC PRINTING PROCESS - The present application relates to a method for concentrating an ink for an electrostatic printing process, wherein the method comprises the steps of:

| 20140242514 | PARTICULATE MATERIAL PRODUCTION METHOD, AND PARTICULATE MATERIAL PRODUCTION APPARATUS - A particulate material production method is provided. The particulate material production method includes ejecting a particulate material composition liquid, which includes an organic solvent and a particulate material composition including at least a resin and dissolved or dispersed in the organic solvent, from at least one nozzle to form droplets of the particulate material composition liquid in a gas phase; and solidifying the droplets of the particulate material composition liquid to prepare particles of the particulate material composition. The droplet solidifying step includes contacting the droplets with a poor solvent for the particulate material composition. | 08-28-2014 |
