Abstract:
1. A composition comprising: an arylsulfinate salt having an anion of Formula I and having a cation that contains at least one carbon atom and either a positively charged nitrogen atom or a positively charged phosphorus atom, wherein Ar 1 is a substituted phenyl, an unsubstituted or substituted C 7-30 aryl, or an unsubstituted or substituted C 3-30 heteroaryl, said substituted Ar 1 having a substituent that is an electron withdrawing group or an electron withdrawing group in combination with an electron donating group; and a triarylsulfonium salt, wherein the composition generates a radical upon exposure to actinic radiation in the wavelength range of 400 to less than 1000 nanometers and wherein the composition is free of an additional component that absorbs actinic radiation in the wavelength range of 400 to less than 1000 nanometers.
