Abstract
A metal-clad laminate having special utility in the production of high resolution printed circuit patterns and preparation of the laminate are described. The laminate preferably comprises a resin-bonded, glass-reinforced substrate, a layer of coupling agent covering and bonded to a major surface of the substrate, a layer of ultra-thin copper adjacent the layer of coupling agent, and a composite bonding layer disposed between the copper layer and the layer of coupling agent. The composite bonding layer comprises copper alloyed with at least one non-copper metal and oxide material of the non-copper metal.
