Open the CIPO recordAbstract From the Canadian patent
Non-conductive real images are formed on substrates by depositing reducible metal salt compositions thereon from an aqueous acidic solution of pHl.5-4 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 by selectively deposited and then exposed or uniformly deposited and then selectively exposed to produce, the real image.
