Photosensitive reducible silver ion-containing compositions

A photosensitive reducible silver ion-containing composition comprising:

• a) a non-hydroxylic-solvent soluble silver complex comprising a reducible silver ion complexed with an α-oxy carboxylate and a primary alkylamine,
• the non-hydroxylic-solvent soluble silver complex being represented by the following formula (I):
• (Ag+)a(L)b(P)c (I)
• wherein L represents the α-oxy carboxylate;
• P represents the 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;
• b) a photosensitizer that is either:
• an electron-accepting photosensitizer that upon absorption of incident electromagnetic radiation, is capable of oxidizing the α-oxy carboxylate;
• or an electron-donating photosensitizer that has an oxidation potential that is greater than the oxidation potential of the α-oxy carboxylate;
• and
• c) a solvent medium comprising at least one non-hydroxylic solvent and less than 10 weight % of water based on the total weight of all solvents in the solvent medium,
• wherein the non-hydroxylic-solvent soluble silver complex is present in an amount of at least 10 weight % and up to and including 90 weight %, based on the total weight of the photosensitive reducible silver ion-containing composition;
• and the photosensitizer is present in an amount of at least 0.5 weight % and up to and including 4 weight %, based on the total weight of the non-hydroxylic-solvent soluble silver complex.
