Summary: | A unit optical fiber having excellent yellowing resistance. The unit optical fiber is constituted by forming on the periphery of a bare optical glass fiber a coating from an ultraviolet-curable resin, and is characterized in that the amount of a photoinitiator remaining unreacted in the coating material is up to 2.4*10<-3> mole equivalents per g of the coating material. The ultraviolet-curable resin is characterized in that it comprises a urethane acrylate and that the polyisocyanate ingredient for the urethane acrylate is an aromatic polyisocyanate and the aromatic polyisocyanate is tolylenediisocyanate. |
