ABSTRACT:
Ultraviolet radiation-curable primary and secondary coating compositions for optical fibers are disclosed. The primary coatings comprise a hydrocarbon polyol-based acrylated or methacrylated aliphatic urethane oligomer; an alkyl acrylate or methacrylate monomer; a refractive index modifying monomer or oligomer; a silane adhesion promoter; and a photoinitiator. The secondary coatings comprise a polyester-based aliphatic urethane acrylate or methacrylate oligomer; an acrylated or methacrylated compound; and a photoinitiator. Also disclosed are optical fibers coated with the secondary coating alone or with the primary and secondary coatings of the invention.
