Methods of making metal patterns on flexible substrate

A method of forming a metal pattern, the method comprising:

• providing a patterned surface, the patterned surface including one or more recessed features and one or more plateau features adjacent to the recessed features;
• coating the patterned surface with a liquid solution to at least partially fill the recessed features;
• solidifying the liquid solution to form a releasable solid layer in the recessed features;
• providing a transfer layer to adhere to the patterned surface;
• removing the transfer layer from the patterned surface to form a patterned construction on the transfer layer, the releasable solid layer being transferred from the patterned surface to the transfer layer and forming
• (a) one or more protrusive features of the patterned construction, wherein the protrusive features of the patterned construction correspond to the recessed features of the patterned surface, and
• (b) recesses which correspond to the plateau features of the patterned surface;
• providing a metal layer on the patterned construction of the transfer layer;
• and
• removing the releasable solid layer along with the metal layer thereon from the protrusive features of the patterned construction to form a metal pattern corresponding to the recesses of the patterned construction on the transfer layer.
