ABSTRACT:
A photosensitive element for the preparation of high quality images using an entirely dry process is provided. The photosensitive portion of this element is prepared from the anode product of an electrolysis of copper in an acid halide bath. Preferably, this material is cuprous halide. The element is then sensitized with an ascorbic acid-containing solution and given an image-wise exposure in actinic or visible light. The image is then developed by giving the element an over-all exposure to monochromatic light of about 5800 angstroms. A high quality, full dry image with good quality and shelf-life is obtained.
