Abstract

An improved peel apart photosensitive element comprises a strippable cover sheet, a photoadherent layer, and a tacky, nonphotosensitive contiguous layer receptive to colorant or particulate material, and a support. The element is useful in applications such as color proofing. Such elements are capable of producing reverse toned or colored images as well as duplicate colored images with greatly improved tonal range and image fidelity.
