No.:  15/231,823  (22)  Filed:  Aug. 9, 2016  A precursor article has a substrate and a photosensitive thin  film or a photosensitive thin film pattern on a supporting  side. The photosensitive thin film and each photosensitive  thin film patterns comprises a non-hydroxylic-solvent  soluble silver complex that is represented by the following  formula  (I):  Primary Examiner  - John J Figueroa  (74)  Attorney, Agent, or Firm  - J. Lanny Tucker  Koen Binnemans et al., "Structure and Mesomorphism of Silver  Alkanoates," Chem. Mater. 2004, 16. 2021-2027.  (Continued)  wherein L represents an a-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, bis 2. A photosensitizer that can either  reduce the reducible silver ion or oxidize the a-oxy car› boxylate having a reduction potential can also be present.  Such precursor articles can be irradiated with UV-visible  radiation to reduce the silver ions to provide electrically› conductive metallic silver in thin films or thin film patterns  in product articles or devices.
