Abstract:
1. A process for preparing a patterned electrical conductor comprising a conductive track pattern on a support, said process comprising the steps of providing a pressure-sensitive or photosensitive element comprising exposing said pressure-sensitive or photosensitive element to pressure or sensitising radiation according to a desired conductive track pattern to form a latent image on said element; subjecting said latent image to a conventional-development step to form said developed element having an image formed by a first metal corresponding to said desired conductive track pattern, together with non-imaged areas; and electroless plating and/or electroplating said metal image with a plating of a second metal to improve the conductivity of said metal image, wherein during said electroless plating and/or electroplating step(s) said developed element is subjected to ultrasonic agitation.
