Radiation Curable Composition for Fiber Optics, Fiber Optic Coating Composition and Radiation Curable Composition

摘要

stable liquid bap photoinitiator d1479 and its use in radiation curable compositions. The present invention relates to radiation curable compositions comprising liquid bis (acyl) phosphine photoinitiator of the formula (I): wherein each of ar1, R3 and ar3 is independently a group. substituted or unsubstituted aryl. The invention also relates to stabilized liquid bis (acyl) phosphine forms of formula (I) and the radiation curable composition comprising said stabilized photoinitiators. The radiation curable compositions are selected from the group consisting of a fiber optic coating composition and a concrete radiation cure coating composition and a metal radiation cure coating composition.
