Abstract
A non-conductive substrate is conditioned for subsequent selective deposition of a metal thereon by providing at least one of the major surfaces of the substrate in roughened form, contacting that surface(s) with a palladium/tin catalyst, activating the catalyst by employing an alkali hydroxide solution, laminating a photosensitive composition to the major surface(s), and exposing the photosensitive composition to actinic light in a predetermined pattern and then developing to provide the predetermined pattern.
