ABSTRACT:
Process for preparation of multicolor images on a single negative-working photosensitive layer which comprises imagewise exposing the layer through a transparency to form tacky image areas; toning the tacky image areas with a toner which becomes swollen or solubilized upon contact with the tacky areas; buffing or rubbing the toned image areas until glossy; and repeating the exposing, toning and buffing or rubbing using a different image-bearing transparency and appropriate toner. The process is useful in preparing multicolor proofs, e.g., maps, textile and wall covering design proofs and samples, etc.
