ABSTRACT:
A method for forming an image, which comprises subjecting an image-recording material comprising a metal layer and an inorganic material layer to imagewise exposure by application of electromagnetic radiation, and then heating the exposed material to cause a thermal doping of the unexposed area of the metal layer. This method permits the formation of negative-positive type images. The product finds a wide range of valuable industrial applications, for example, as an ordinary image-recording material, laser recording material, electron beam recording material or microrecording material, and also for producing a print-wiring plate, relief metal plate for relief and lithographic printing, or a master for electrostatic printing.
