Compositions are provided that include an electron donor and a sensitizing compound. More specifically, the electron donor is an arylsulfinate salt. Methods of polymerization are also provided that can be used to prepare polymeric material from a photopolymerizable composition that includes ethylenically unsaturated monomers and a photoinitiator system. The photoinitiator system includes an electron donor and a sensitizing compound.

We claim: 1. An arylsulfinate salt comprising: an anion of Formula I wherein Ar1 is a substituted phenyl, an unsubstituted or substituted C7-30 aryl, or an unsubstituted or substituted C3-30 heteroaryl, said substituted Ar1 having a substituent that is an electron withdrawing group or an elect
We claim: 1. An arylsulfinate salt comprising: an anion of Formula I wherein Ar1 is a substituted phenyl, an unsubstituted or substituted C7-30 aryl, or an unsubstituted or substituted C3-30 heteroaryl, said substituted Ar1 having a substituent that is an electron withdrawing group or an electron withdrawing group in combination with an electron donating group; and a cation comprising a ring structure comprising a 4 to 12 member heterocyclic group with a positively charged nitrogen atom and at least one other heteroatom selected from nitrogen, oxygen, sulfur, or combinations thereof, said heterocyclic group being saturated or unsaturated, wherein said ring structure can be unsubstituted or substituted with a substituent selected from an alkyl, aryl, acyl, alkoxy, aryloxy, halo, mercapto, amino, hydroxy, azo, cyano, carboxy, alkoxycarbonyl, aryloxycarbonyl, or halocarbonyl group. 2. The arylsulfinate salt of claim 1, wherein said heterocyclic group is fused to a cyclic or bicyclic group that is saturated or unsaturated and that has 0 to 3 heteroatoms. 3. The arylsulfinate salt of claim 1, wherein the heterocyclic group is a heterobicyclic group. 4. The arylsulfinate salt of claim 1, wherein the heterocyclic group is selected from a pyrazolium ion, imidazolium ion, triazolium ion, isoxazolium ion, oxazolium ion, thiazolium ion, isothiazolium ion, oxadiazolium ion, oxatriazolium ion, dioxazolium ion, oxathiazolium ion, pyridazinium ion, pyrimidinium ion, pyrazinium ion, piperazinium ion, triazinium ion, oxazinium ion, oxathiazinium ion, oxadiazinium ion, or morpholinium ion. 5. The arylsulfinate salt of claim 1, wherein the heterocyclic group is selected from an indazolium ion, benzimidazolium ion, benzotriazolium ion, benzisoxazolium ion, benzoxazolium ion, benzothiazolium ion, benzisothiazolium ion, benzoxadiazolium ion, benzoxatriazolium ion, benzodioxazolium ion, benzoxathiazolium ion, purinium ion, cinnolinium ion, quinazolinium ion, benzopyrazinium ion, benzopiperazinium ion, benzotriazinium ion, benzoxazinium ion, benzoxathiazinium ion, benzoxadizinium ion, or benzomorpholinium ion. 6. The arylsulfinate salt of claim 1, wherein the Ar1 group of the arylsulfinate salt is a substituted phenyl, an unsubstituted or substituted naphthyl, or an unsubstituted or substituted anthraquinonyl, said substituted Ar1 having a substituent that is an electron withdrawing group or an electron withdrawing group in combination with an electron donating group. 7. The arylsulfinate salt of claim 1, wherein the anion of the arylsulfinate salt is a benzenesulfinate substituted with an electron withdrawing group electron selected from halo, cyano, fluoroalkyl, perfluoroalkyl, carboxy, alkoxycarbonyl, aryloxycarbonyl, halocarbonyl, formyl, carbonyl, sulfo, alkoxysulfonyl, aryloxysulfonyl, perfluoroalkylsulfonyl, alkylsulfonyl, azo, alkenyl, alkynyl, dialkylphosphonato, diarylphosphonato, aminocarbonyl, or combinations thereof. 8. The arylsulfinate salt of claim 1, wherein the arylsulfinate salt is N,N-dimethylmorpholinium 4-cyanobenzenesulfinate, 1-methyl-4-aza-1-azoniabicyclo [2.2.2]octane 4-cyanobenzenesulfinate, 3-ethyl-2-methylbenzoxazolium 4-cyanobenzenesulfinate, N-hexadecylpyridinium 4-cyanobenzenesulfinate, or combinations thereof. 9. An arylsulfinate salt comprising: an anion of Formula I wherein Ar1 is a substituted phenyl, a substituted C7-30 aryl, or an unsubstituted or substituted C3-30 heteroaryl, said substituted Ar1 having a substituent that is an electron withdrawing group or an electron withdrawing group in combination with an electron donating group, wherein the electron withdrawing group electron is selected from cyano, carboxy, alkoxycarbonyl, aryloxycarbonyl, halocarbonyl, formyl, carbonyl, sulfo, alkoxysulfonyl, aryloxysulfonyl, perfluoroalkylsulfonyl, alkylsulfonyl, azo, alkenyl, alkynyl, dialkylphosphonato, diarylphosphonato, aminocarbonyl, or combinations thereof and a cation is of Formula III where each R2 is independently an unsubstituted alkyl, an alkyl substituted with a hydroxy, an unsubstituted aryl, or an aryl substituted with an alkyl, hydroxy, or combinations thereof. 10. The arylsulfinate salt of claim 9, wherein the compound is tetraphenylphosphonium 4-cyanobenzenesulfinate. 11. The arylsulfinate salt of claim 9, wherein the Ar1 group of the arylsulfinate salt is a substituted phenyl, a substituted naphthyl, or an unsubstituted or substituted anthraquinonyl, said substituted Ar1 having a substituent that is an electron withdrawing group or an electron withdrawing group in combination with an electron donating group. 12. The arylsulfinate salt of claim 9, wherein the anion of Formula I is 4-cyanobenzenesulfinate. 13. The arylsulfinate salt of claim 9, wherein the anion of Formula I is 4-ethoxycarbonylbenzenesulfinate. 14. An arylsulfinate salt comprising: an anion of Formula I wherein Ar1 is a substituted phenyl, a substituted C7-30 aryl, or a substituted C3-30 heteroaryl, said substituted Ar1 having a substituent that is an electron withdrawing group in combination with an electron donating group, wherein the electron withdrawing group electron is selected from halo, fluoroalkyl, perfluoroalkyl, or combinations thereof and wherein the electron donating group is selected from a primary amino, secondary amino, tertiary amino, hydroxy, alkoxy, aryloxyl, or combinations thereof and a cation is of Formula III where each R2 is independently an unsubstituted alkyl, an alkyl substituted with a hydroxy, an unsubstituted aryl, or an aryl substituted with an alkyl, hydroxy, or combinations thereof.
