The invention relates to radiation curable compositions comprising a liquid 0/s(acyl)phosphine photo initiators of formula (Ï): 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.
