Abstract:
1. An optical fiber coating composition which comprises at least one ethylenically unsaturated polymerizable compound and a liquid photoinitiator blend, wherein the liquid blend consists essentially of where the bisacylphosphine oxide photoinitiator is bis(2,4,6-trimethylbenzoyl)phenylphosphine oxide or bis(2,4,6-trimethylbenzoyl)-(2,4-bis-pentyloxyphenyl)phosphine oxide, where the monoacylphosphine oxide photeinitiator is 2,4,6-trimethylbenzoylethexyphenylphosphine oxide or 2,4,6-trimethylbenzoyldiphenylphosphine oxide and the α-hydroxy ketone photoinitator is α-hydroxycyclohexylphenyl ketone or 2-hydroxy-2-methyl-1-phenyl-1-propanone.
