Abstract:
An imaging system wherein an imaging member comprising a supporting substrate, a layer of electrically conductive material, a layer comprising carbon, a softenable layer comprising solvent soluble softenable material contacting said layer comprising carbon, and a layer of particulate material comprising electrically photosensitive material embedded at the surface of said softenable material, is imaged in a migration imaging system wherein said member has an electrical latent image formed thereon and is first developed by contacting said member with a first solvent, and further developed by contacting with a second solvent to form an optically negative or optically positive image comprising carbon on the supporting substrate.
Abstract:
An image comprising migration material residing on a metallic conductive substrate and formed in accordance with the migration imaging process is stabilized and fixed onto the substrate by heating the substrate and the migration material to produce a chemical reaction therebetween resulting in a permanent stable image having high density and resolution.
Abstract:
A METHOD OF IMAGING WHICH COMPRISES PROVIDING AN IMAGING STRUCTURE HAVING A SUPPORT, AND AN OVERLAYER OF SOFTENABLE MATERIAL CONTAINING A PARTICULATE PHOTOSENSITIVE OVERLAYER, SELECTIVELY IMAGING A DESIRED PORTION OF SAID STRUCTURE BY FORMING A LATENT IMAGE ON SAID PORTION, DEVELOPING SAID LATENT IMAGE BY UNIFORM EXPOSURE TO A DEVELOPING AGENT, WHEREBY AN IMAGE IS FORMED BY THE SELECTIVE MIGRATION OF PHOTOSENSITIVE PARTICLES IN IMAGE CONFIGURATION, AND SELECTIVELY FORMING AT LEAST ONE ADDITIONAL LATENT IMAGE ON SAID IMAGING STRUCTURE, AND DEVELOPING SAID LATENT IMAGE BY UNIFORM EXPOSURE TO A DEVELOPING AGENT, WHEREBY AN ADDITIONAL IMAGE IS FORMED BY THE SELECTIVE MIGRATION OF PHOTOSENSITIVE PARTICLES IN IMAGE CONFIGURATION.
