Physical development of a thin reversibly activatable photoconductor element having a resinous barrier layer
Abstract
Abstract THIS INVENTION RELATES TO A PHOTOGRAPHIC IMAGING MEDIUM COMPRISING A SUBSTRATE, REVERSIBLY ACTIVATABLE PHOTOCONDUCTOR LAYER PREFERABLY HAVING A THICKNESS OF LESS THAN ABOUT 2 MICRONS, AND A WATER OR ALCOHOL SOLUBLE, TRANSPARENT BARRIER LAYER HAVING A LOW PERMEABILITY TO OXYGEN OVER SAID RADIATION ACTIVATABLE PHOTO-CONDUCTOR LAYER. THE PHOTOGRAPHIC IMAGING MEDIUM IS CHARACTERIZED BY THE BARRIER LAYER WHICH SUBSTANTIALLY PROLONGS DECAY TIME OF A LATENT IMAGE STORED IN THE PHOTOCONDUCTOR WHICH LATENT IMAGE HAS BEEN FORMED BY EXPOSURE TO A SOURCE OF ACTIVATING RADIATION. PROLONGED DECAY TIME IS BELIEVED TO BE DUE TO THE BARRIER LAYER PREVENTING MASS TRANSPORT OF OXYGEN FROM THE ATMOSPHERE TO THE PHOTOCONDUCTOR.
