Abstract

A photosensitive element is disclosed, and a process of forming an image with it, comprising, in order, a support with an optional subbing layer (1), a metal image forming layer, a photosensitive layer, and a transparent cover sheet with an optional subbing layer (2). After exposure a delamination step is performed thereby giving rise to a positive and a negative metal image. In a most preferred embodiment the metal layer is a bismuth layer.
