Abstract
A method for providing electrically-conductive silver-containing metal in a thin film or one or more thin film patterns on a substrate. Electrically-conductive metallic silver is provided from a non-hydroxylic-solvent soluble silver complex represented by the following formula (I): (Ag+)a(L)b(P)c (I) wherein L represents an α-oxy carboxylate; P represents a 5- or 6-membered N-heteroaromatic compound; 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. The reducible silver ions in the photosensitive thin film or photosensitive thin film pattern can be photochemically converted to electrically-conductive metallic silver in the thin films or thin film patterns by irradiation with electromagnetic radiation having a wavelength within the range of at least 150 nm and up to and including 700 nm.
