Abstract
The present invention provides a method of manufacturing an optical fiber coating with a greater adhesive strength between the primary coating layer and the colored layer as the secondary coating layer. This method prevents the colored layer from being removed together with the bundle coating layer when the bundle coating layer is removed, for example, prior to joining. A colored layer is provided on the outer circumference of the primary coating layer while keeping the surface of the primary coating layer in an unhardened state to thereby improve the adhesive strength between the primary coating layer and the colored or secondary layer.
