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.

High resolution superimposed images from photopolymer electrographic

Process for preparation of a correct reading image comprising

Correct-reading images from photopolymer electrographic master

Xeroprinting process involving imagewise exposing a photopolymer master, charging on a conductive support, toning with dry or liquid electrostatic toner, and transferring to another surface. Photopolymer systems comprising preferred combinations of polymeric binders, ethylenically unsaturated monomers. HABI initiators and chain transfer agents.

Xeroprinting with photopolymer master

Process for formation of a hardened, insoluble or crosslinked stencil or resist image on a substrate, e.g., having a metal surface such as copper, and modifying the substrate or image surface comprising:
