The insulated board is first primed with an adhesion promoter and a negative mask of alkali soluble but acid resistant varnish, esp., no volak resin based is applied. The board is then placed in a bath of Ag or Pd catalyst soln. following which the mask and catalyst adhering to it are completely removed in a second bath leaving a pattern of catalyst corresponding to the desired conductor pattern.
