ABSTRACT:
A method of manufacturing a foil material having a metal layer on a region thereof comprises applying to a backing foil a layer of a soluble material such as a lacquer to which a hardening agent is then applied in selected regions thereof, the hardening agent reacting with the soluble material to cause it to harden. A coating of metal is then applied over the layer of soluble material and the portions of the layer of soluble material which have remained soluble are then removed, thereby also removing the portions of the layer of metal thereon and leaving the metal on the hardened portions of the layer of soluble material. The foil material made by the method is also disclosed.
