Abstract:
1. A composition comprising: an electron donor comprising an arylsulfinate salt having a anion of Formula I and a cation having at least one carbon atom and either a positively charged nitrogen atom or a positively charged phosphorus atom, said electron donor having an oxidation potential in N,N-dimethylformamide of 0.0 to +0.4 volts versus a silver/silver nitrate reference electrode, wherein Ar the cation is selected from where each R 2 is independently an unsubstituted alkyl, an alkyl substituted with a hydroxy, an unsubstituted aryl, or an aryl substituted with an ethyl, hydroxy, or combinations thereof; or a sensitizing compound capable of absorbing a wavelength of actinic radiation in the range of 250 to 1000 nanometer, the sensitizing compound comprising a dye selected from a ketone, xanthene, acridine, thiazole, thiazine, oxazine, azine, aminoketone, aromatic polycyclic hydrocarbon, p-substituted aminostyryl ketone, aminotriaryl methane, cyanine, pyridinium, or triarylmethane.
