ABSTRACT:
Process for preparation of high resolution image exposing imagewise a photopolymerizable element having a removable cover sheet and a conductive support or a temporary support which is replaced by a conductive support, stripping the cover sheet and laminating the imagewise exposed photopolymerizable layer to a second exposed photopolymerizable layer on a temporary support, removing the temporary support, charging electrostatically the exposed photopolymerizable layers, developing, e.g., liquid electrostatic developer or dry toner developer, and optionally transferring the developed image to a receptor surface, e.g., paper. The process is useful in preparing multiple copies in more than one version, e.g., logos, headlines, corrections, etc.
