摘要： A method of coating a liquid or solid particulate core involves dropping or suspending the particulate core in an atmosphere and then applying a liquid coating while the particulate core is dropped or suspended, the applying of the liquid coating being done by either (a) spraying the liquid coating onto the particulate core with an ink jet or (b) moving the particulate core through a fog of the liquid coating. In a further embodiment, the method can be used for encapsulating a liquid or solid particulate core within a polymeric shell by dropping or suspending the particulate core in an atmosphere, then applying by one of the above-mentioned methods a first coating composition containing a first reactant to the particulate core while the particulate core is being dropped or suspended, and subsequently exposing the particulate core coated with the first coating composition to a second composition containing a second reactant which reacts with the first reactant, which second composition is immiscible with the first coating composition, whereby the polymeric shell is formed by interfacial polymerization. By these methods, the formation of membranes or polymer shells around a variety of particulate core materials can be done using precise amounts of coating materials, thereby reducing waste and improving efficiencies of the process.

摘要： A particulate encapsulated Gyricon element includes a Gyricon sphere encapsulated within a shell that also contains a dielectric fluid in which the Gyricon sphere is able to rotate. The shell is preferably formed around the Gyricon sphere and the dielectric fluid by interfacial condensation polymerization. Display elements such as electric paper can be readily derived by coating the encapsulated Gyricon elements upon a substrate. Display elements can thus be readily achieved without the need for an expensive elastomer binder sheet or the need to have the sheet in contact with a dielectric fluid.

摘要： A dampening fluid useful in offset ink printing applications contains water and a surfactant whose structure can be altered. The alteration in structure aids in reducing accumulation of the surfactant on the surface of an imaging member. The surfactant can be decomposed, switched between cis-trans states, or polymerizable with ink that is subsequently placed on the surface.
