Abstract
A patterned conductive article 200 includes a substrate 210 including a unitary layer 210-1 and includes a micropattern of conductive traces 220 embedded at least partially in the unitary layer. Each conductive trace extends along a longitudinal direction (y-direction) of the conductive trace and includes a conductive seed layer 230 having a top major surface 232 and an opposite bottom major surface 234 in direct contact with the unitary layer; and a unitary conductive body 240 disposed on the top major surface of the conductive seed layer. The unitary conductive body and the conductive seed layer differ in at least one of composition or crystal morphology. The unitary conductive body has lateral sidewalls 242, 244 and at least a majority of a total area of the lateral sidewalls is in direct contact with the unitary layer.
