    摘要: Optical fiber coating compositions which comprise at least one ethylenically unsaturated polymerizable compound and a photoinitiator blend, wherein the blend comprises (a) bis(2,4,6-trimethylbenzoyl)phenylphosphine oxide and (b) 2,4,6,-trimethylbenzoylethoxyphenylphosphine oxide in an (a):(b) weight:weight ratio of between about 1:10 and about 1:8; or (c) bis(2,4,6-trimethylbenzoyl)phenylphosphine oxide, (d) 2,4,6,-trimethylbenzoylethoxyphenylphosphine oxide and (e) 2-hydroxy-2-methyl-1-phenyl-1-propanone in a (c):(d):(e) weight:weight:weight ratio between about 3:1:14 and about 4:1:16; or (f) bis(2,4,6-trimethylbenzoyl)phenylphosphine oxide and (g) 2-hydroxy-2-methyl-1-phenyl-1-propanone in a (f):(g) weight:weight ratio of between about 1:3 and about 1:5 exhibit fast photospeed, very low color and fast photobleaching. The photoinitiator blends have low volatility, high shelf life stability and high compatibility with resins and monomers. The photoinitiator blends are for example liquid and easy to use.
