Abstract:
A resin composition for coating an optical fiber comprises: a base resin containing a photopolymerizable compound and a photopolymerization initiator; and hydrophobic inorganic oxide particles, wherein the photopolymerizable compound comprises urethane (meth)acrylate and aliphatic epoxy (meth)acrylate, and the content of the aliphatic epoxy (meth)acrylate is 1.0% by mass or more and 45% by mass or less based on the total amount of the photopolymerizable compound.
