Abstract: The present invention provides a method for forming a metal image in which a resist film is provided at an image portion and then etching processing is performed to thereby form the metal image comprising the steps of: (1) forming an image comprised of concave surface portions on a metal surface; (2) forming a resist film on the metal surface; and (3) exposing the resist film to such an extent that at the concave portions of the resist film is not made wholly soluble.

Abstract: The invention provides a flexible composite comprising a resilient structured conductive member extending between opposite surfaces of the composite and a polymeric coating on each side of the conductive member to define therewith the opposite surfaces. The conductive member comprises a plurality of tapered elements extending to opposite surfaces of the composite. The conductive member thereby provides a conductive pathway through the composite which is adapted to compress and return towards its original shape as a force is applied and decreased.
