ABSTRACT:
Non-conductive real images are formed on substrates by depositing reducible metal salt compositions thereon from an aqueous acidic solution of pH 1.5-5 containing bromide ions and exposing the coated substrates to radiant energy to reduce the metal salt to metallic nuclei and to produce a real image of metal, which is intensified and built up by electroless metal deposition. The metal salt composition can either be selectively deposited and then exposed, or uniformly deposited and then selectively exposed, to produce the real image.
