ABSTRACT:
A method for producing a display capsule includes the following steps. A multichromal bead having at least two surfaces differing from each other in optical and electrical characteristics is formed. A dispersing agent on an outer surface of the multichromal bead is applied, preferably via spray coating. The multichromal bead is then encapsulated. The invention is also directed to a method for producing multichromal capsules. A multichromal bead having at least two surfaces differing from each other in optical and electrical characteristics and further includes a charge control additive. A dispersing agent is applied on an outer surface of the multichromal bead to prevent diffusion of the charge control additive from the multichromal bead. The multichromal bead is encapsulated at an encapsulation reaction temperature greater than 40° C.
