Abstract: Disclosed is a migration imaging member comprising a first conductive layer, a layer of softenable material containing migration marking material, and a conductive overlayer on the surface of the imaging member spaced from the first conductive layer. The imaging member also contains a charge transport material either in the layer of softenable material or in a separate layer situated between the first conductive layer and the conductive overlayer. In a specific embodiment, the conductive overlayer is coated on the surface of the imaging member in separate, distinct frames separated from each other by uncoated areas of the imaging member. Also disclosed are apparatuses and processes for preparing the above imaging members and apparatuses and processes for exposing and developing the above imaging members.

Abstract: Disclosed is a printing plate precursor which comprises a base layer, a layer of photohardenable material, and a layer of softenable material containing photosensitive migration marking material. Alternatively, the precursor can comprise a base layer and a layer of softenable photohardenable material containing photosensitive migration marking material. Also disclosed are processes for preparing printing plates from the disclosed precursors.
