Abstract

See full text

Described herein is a method for coating optical fiber where the coating has been cured by application of a source of monochromatic actinic radiation, such as a light emitting diode, wherein the coating contains a urethane(meth)acrylate oligomer; a (meth)acrylate diluent monomer; a diluent monomer having an electron donating group adjacent to the vinyl group, such as a vinyl ether monomer; and a photoinitiator. Also described are compositions which are capable of undergoing photopolymerization when coated on an optical fiber and when irradiated by a light emitting diode (LED) with improved surface cure and reduced yellowing. Also described are the coated optical fibers produced by such processes and compositions.
