The invention relates to radiation curable compositions comprising a liquid 0/s(acyl)phosphine photo initiators of formula (I): wherein each of Ar1, Ar2 and Ar3 is independently a substituted or unsubstituted aryl group. The invention also relates to stabilized forms of liquid bis(acyl)phosphines of formula (I) and radiation curable composition comprising said stabilized photoinitiators. The radiation curable compositions are selected from the group consisting of an optical fiber coating composition and a coating composition capable of radiation cure on concrete and a coating composition capable of radiation cure on metal.

1. A stabilized liquid bis(acyl)phosphine of formula (I): wherein each of Ar1, Ar2 and Ar3 is independently selected from the group consisting of a phenyl group, a methylphenyl group, an ethylphenyl group, a dimethylphenyl group, a trialkylphenyl group, an isopropylphenyl group, a tert-butyl phenyl group, a methoxy phenyl group, a dimethoxyphenyl group, an ethoxy phenyl group, a diethoxy phenyl group, an isopropoxy phenyl group, a thiomethoxy phenyl group, a naphthyl group, a thiophenyl group and a pyridyl group; andwherein said stabilized liquid bis(acyl)phosphine is liquid at 20° C. and is stabilized as a composition comprising less than about 1.0 wt. % of water. 2. The stabilized liquid bis(acyl)phosphine of claim 1, wherein the trialkylphenyl group is a trimethylphenyl group. 3. The stabilized liquid bis(acyl)phosphine of claim 2, wherein the trimethylphenyl group is a 2,4,6-trimethylphenyl group. 4. The stabilized liquid bis(acyl)phosphine of claim 1, wherein the stabilized phosphine is stabilized liquid bis(2,4,6-trimethylbenzoyl)phenylphosphine, wherein Ar1 is a phenyl group and each of Ar2 and Ar3 is a 2,4,6-trimethylphenyl group. 5. A radiation curable composition comprising the stabilized liquid bis(acyl)phosphine of claim 1 and at least one free-radical polymerizable component. 6. The radiation curable composition of claim 5, wherein said composition is selected from the group consisting of an optical fiber coating composition and a coating composition capable of radiation cure on concrete. 7. The radiation curable composition of claim 6, wherein said composition is an optical fiber coating composition. 8. The optical fiber coating composition of claim 7, wherein the optical fiber coating composition is selected from the group consisting of a primary coating, a secondary coating, an ink coating, an up jacketing coating, a buffer coating and a matrix coating. 9. The radiation curable composition of claim 6, wherein said composition is a coating capable of radiation cure on concrete. 10. The radiation curable composition of claim 5, wherein the composition is curable by UV light generated by a conventional UV light source. 11.
