  • Photocurable and antistatic resin composition for coating optical fiber
    Patent number: 7524890
    Abstract: The present invention is directed to a photocurable and antistatic resin composition for coating an optical fiber, comprising (A) a photopolymerizable urethane acrylate oligomer, (B) a reactive monomer having at least one (meth)acrylate or vinyl group, (C) a photoinitiator, and (D) an antistatic agent compatible with the oligomer and monomer components, and optionally (E) a pigment or dye. The coating of the inventive composition can increase the productivity of the optical fiber, and provide an optical fiber having a uniform coating layer.
