ABSTRACT:
A method of making an electrically conducting metal pattern on a superficially non-conducting support which comprises imagewise exposing to light a photosensitive material containing either a diazosulfide or a diazosulfonate, which produces a light reaction product which is capable of forming free silver and mercury metal from water-soluble silver and mercurous compounds. A mixture of water and at least one solvent from the group consisting of chloroform, toluene, ethylacetate, liquid alcohols and ketones is used in the treatment of the exposed photosensitive material to form a latent image.
