摘要： A method of making a multichromal sphere includes the steps of preparing a composition of at least (1) a matrix material and (2) at least two sets of particles, each of the sets of particles having a color different from at least one of another of the sets of particles and a segregation (e.g., an electrical or magnetic) property different from at least one of another of the sets of particles, encapsulating the composition within a shell to form an encapsulated sphere, immobilizing the encapsulated sphere in a manner to restrict at least rotation of the encapsulated sphere, subjecting the immobilized encapsulated sphere to an external field associated with the segregation property different among the sets of particles, under conditions in which the sets of particles are able to migrate within the matrix material, thereby producing color segregation in the immobilized encapsulated sphere, and solidifying the matrix material while substantially maintaining the color segregation. In the multichromal spheres, each of the sets of particles is segregated within a separate segment of the solidified matrix material of the core on the basis of the different segregation property.

摘要： A dynamic reimageable document or electric paper can be formed from ordinary substrates such as paper, transparencies or fabric by printing of microencapsulated Gyricon beads onto one or more discrete surface areas of the substrate. The substrate can include both fixed print regions formed by conventional fixed ink processes and dynamic reimageable regions formed by the Gyricon beads. The Gyricon beads are preferably bichromal and of contrasting colors, such as black/white so as to be changeable to display two states by selective application of electromagnetic force to the beads. By providing bichromal beads in differing color combinations, such as red/white and black/white, a multi-colored document can be achieved in which various fields of the document, representing text, images or graphics, may be in differing colors. Moreover, operations to perform both imaging or erasure can act on the discrete reimageable regions so that the versatility of the electric paper can be enhanced. The Gyricon beads may be dispersed in a solution to form a liquid Gyricon toner that can be directly marked, such as by a jet nozzle, into a desired pattern on the substrate.
