ABSTRACT:
A method for forming a metal layer with a positive pattern on a plastic sheet or plate substrate which comprises printing an oil-soluble, water-insoluble ink on the substrate to provide a negative pattern, forming a metal layer on said substrate by dry metal plating, immersing the substrate in a hydrocarbon having 6-17 carbon atoms, preferably kerosene, and removing the ink layer and metal layer thereon by applying supersonic vibration to the substrate in the kerosene.
