deposited copper foil layer having opposing first and second sides and a thickness
of from 0.1 micron to 15 microns and the entire metal foil layer thickness having
been deposited from a copper containing alkaline electrolyte, and a release layer
effective to facilitate separation of the metal foil layer from the carrier strip
disposed between and contacting both the first side of the carrier strip and the
second side of the metal foil layer.
