Abstract: A display device includes at least one cell containing a fluid having colored particles dispersed in the fluid and at least one dot field applicator associated with the cell. The dot field applicator may be a dote electrode.

Abstract: A reimageable printing member such as a printing plate for use in flexography, includes a layer having a multiplicity of channels therein. The layer has an open side to which the multiplicity of channels are open. The reimageable printing member further includes a filed generator such as an electrode or a magnetic field generator associated with the multiplicity of channels and generating an electric and/or magnetic field. The multiplicity of channels are individually addressable, thereby permitting the field to be applied to selected ones of the multiplicity of channels so that the marking material within such selected channels can be manipulated to move out of the channel and onto an image receiving substrate brought into contact with the open side of the layer, thereby forming an image on the substrate.

Abstract: A reimageable printing member such as for use in flexography, includes a layer having a multiplicity of holes, wherein the holes include therein a dimension change material and a printing material upon the dimension change material. Thus, the holes house vertically expandable units, the top portion of which is capable of protruding out of an opening of the hole at a top surface of the layer. Each of the holes may be individually addressed to provide a stimulus that initiates a change in dimension in the dimension change material. In this manner, selected ones of the units may be made to print a corresponding portion of an image on an image receiving substrate brought into contact with the printing member.

Abstract: An emulsion polymerization process comprising polymerizing monomer in an emulsion in a reaction vessel at a first temperature to form a resin; cooling the reaction vessel to a second temperature that is above the softening point of the resin yet below the temperature required for significant depolymerization reaction to occur; and adding water to the cooled reaction vessel in an amount sufficient to effect phase inversion with mixing for a sufficient time to form an aqueous latex emulsion in the absence of a surfactant.

Abstract: A protective, switchable layer adapted for use in transient imageable documents is disclosed. The protective layer can be disposed on an underlying photochromic layer and enables writing or imaging the underlying layer. The protective layer prevents unintentional writing on the photochromic layer, such as can otherwise occur from exposure to certain wavelengths of light.

Abstract: A device composed of: (a) a first liquid crystal composition including a first liquid crystal and a first liquid crystal domain stabilizing compound, wherein the first liquid crystal composition switches between a strongly scattering state of a first plurality of smaller liquid crystal domains that strongly scatters a predetermined light and a weakly scattering state of a second plurality of larger liquid crystal domains that weakly scatters the predetermined light; and (b) a second liquid crystal composition including a second liquid crystal and a second liquid crystal domain stabilizing compound, wherein the second liquid crystal composition switches between a strongly scattering state of a first plurality of smaller liquid crystal domains that strongly scatters the predetermined light and a weakly scattering state of a second plurality of larger liquid crystal domains that weakly scatters the predetermined light, wherein the second liquid crystal composition and the first liquid crystal composition are in

Abstract: A process for forming curable powder comprises providing an aqueous dispersion of particles of curable resin and optionally particles comprising at least one curing agent; aggregating the particles optionally with the curing agent to form aggregated particles; coalescing the aggregated particles to form fused particles; and removing the fused particles from the aqueous dispersion. By this process, a curable powder is formed. The curable powder may be used in powder coating.
