A plastic optical fiber includes a plastic optical fiber body and a coloring member covering a peripheral surface of the plastic optical fiber body. The coloring member is made from a cured product of a curable composition containing an active-energy-ray-curable multifunctional acrylate and a coloring agent. The reaction percentage yield of the vinyl group of the active-energy-ray-curable multifunctional acrylate in the coloring member is 85% or more.

Plastic optical fiber

A curable resin composition, comprising a compound represented by the following general formula (1): wherein X is a functional group comprising a reactive group, and Rand Reach independently represent a hydrogen atom, or an aliphatic hydrocarbon group, aryl group or heterocyclic group that may have a substituent; and at least organometallic compound selected from the group consisting of metal alkoxides and metal chelates.
