Abstract
A precursor article has a substrate and a photosensitive thin film or photosensitive thin film pattern on one or both supporting sides. A non-hydroxylic-solvent soluble silver complex is present that is represented by the following formula (I): (Ag+)a(L)b(P)c (I) wherein L represents an α-oxy carboxylate; P represents a primary alkylamine; a is 1 or 2; b is 1 or 2; and c is 1, 2, 3, or 4, provided that when a is 1, b is 1, and when a is 2, b is 2. A photosensitizer can also be present to enhance photosensitivity for conversion of reducible silver ions to electrically-conductive silver metal in a resulting product article or device. The electrically-conductive silver metal can be provided as a uniform electrically-conductive silver metal-containing thin film or layer, or as one or more electrically-conductive silver metal-containing thin film patterns.
