ABSTRACT:
A planar array of microcells is formed in a support. An electrostatic charge pattern is established on the support differentiating first and second interlaid sets of microcells. An electrographic imaging composition is introduced into the first set of microcells, and a second, differing imaging composition is introduced into the second set of microcells. Multicolor photographic elements, particularly dye image transfer photographic elements, can be prepared.
