<p>A process for forming microcellular imaging elements comprising a support having first and second major surfaces, a planar array of microcells 1 to 200 microns in width opening toward the first major surface, which comprises selectively introducing a first imaging composition into a first set of microcells, and a second, differing imaging composition into a second set of microcells forming an interlaid pattern with said first set of mtcrocells, characterized in that the portion of the support (100) having the microcells (102) is photoconductive, and in that an electrostatic charge pattern is established on said support differentiating said first and second sets of microcells, and a first electrographic imaging composition is introduced selectively into the first set of microcells. The support optionally has an electrically conductive layer (116). </p> |
