Abstract: A stabilized color pigment dispersion includes a phosphated polymer, a color pigment stabilized in the phosphated polymer, and an aqueous carrier. The color pigment comprises one or more oxide color pigments and is essentially free from metallic pigments. The stabilized color pigment dispersion comprises in a range of from about 20% to about 80% of water, percentage based on the total weight of the stabilized color pigment dispersion.

Abstract: Systems and methods for handling instructions in a pre-boot execution environment are disclosed. A controlling server may connect to a pre-boot control (PBC) proxy server via a network and transmit over the network from the controlling server to the PBC proxy server instructions for a pre-boot task to be completed by a network bootstrap program (NBP) on a client system connected to the PBC proxy server. The NBP may poll the PBC proxy server to determine if any instructions for a pre-boot task to be completed are available. If instructions are available, the instructions may be transmitted from the PBC proxy server to the NBP, and the pre-boot task executed by the NBP on the client system. If instructions are not available, the NBP may sleep for a specified interval of time and repoll the PBC proxy server after the specified interval.

Abstract: This invention pertains to aqueous inkjet inks containing self-dispersing pigments and effective amounts of one or more multivalent cations, said inks having increased optical density when printed.

Abstract: A process is provided in which a pigment is oxidated with ozone in an aqueous environment in which the mixture of ozone, water and pigment is subjected to a dispersive mixing operation; and/or the pH of the mixture is maintained in a range of 6-8, whereby the pigment is self-dispersing and preferably has an acid value of less than 3 ?moles/M2. Pigments from this process and ink jet inks containing the self-dispersing pigments, are also provided.

Abstract: A method of producing self dispersible organic pigment particles stabilized by the method. The method includes modifying organic pigment particles and then contacting the surface modified particles with an aqueous vapor entrained in a carrier gas to produce the stabilized organic pigment particles. Typically the pigment particles are modified by exposing their surfaces to ozone or a plasma-activated process gas. The surface stabilizing method prevents the violent exothermic reaction, which occurs when surface modified pigment particles are exposed to ambient air. The method is accomplished in a device, which includes a reactor, means for introducing in the reactor aqueous vapor entrained in a carrier gas and an agitator assembly for deagglomerating during surface modification the pigment particles placed in the reactor.

Abstract: A method for treating the surface of substantially each deagglomerated particle of an array of easily agglomerated particles by contacting deagglomerated particles with a plasma-activated gas species and modifying the surfaces of the deagglomerated particles to aid subsequent incorporation of the particles into a matrix composition; the module for deagglomerating and dispersing the particles into the plasma-activated gas; the apparatus that comprises the deagglomeration module (322) and a reaction chamber (20) in which the particles are treated with the plasma-activated gas; the method for deagglomerating particles that may reagglomerate after plasma treatment; and a color composition containing plasma-treated pigment particles.

Abstract: A method for optimizing the processing of continuous media mills is disclosed. It has been found that using a differential pressure device to measure the pressure drop across the mill allows the on line determination of the state of media fluidization in the mill. Operation within an optimum mill base flow rate range is needed to have good fluidization of the media so that grinding can be efficient. Using differential pressure measurement allows a precise determination of the mill base flow rate range which provides full fluidization of the media and mill base flow rate control within that range.
