Abstract
A method is used to provide an electrically conductive article. The method includes: (i) providing a continuous polymeric web of a transparent polymeric substrate; (ii) forming a first photocurable pattern on at least a first portion on a first supporting side of the continuous polymeric web using a photocurable composition comprising metal particles; (iii) exposing the photocurable pattern to form a photocured pattern on the first portion of the first supporting side; (iv) electrolessly plating the photocured pattern with an electrically-conductive metal to form an electrically-conductive metal pattern; and (v) forming a dry outermost polymeric coating over at least part but not all of the electrically-conductive pattern, the dry polymeric coating having a dry thickness of less than 5 μm, an integrated transmittance of at least 80%, and comprising a non-crosslinked thermoplastic polymer having a glass transition temperature (Tg) that is equal to or greater than 65° C.
