Abstract
The specification describes optical fiber coating materials and methods for making optical fiber gratings wherein the material of the optical fiber coatings comprises vinyl ether functionalized monomers, together with oligomeric or polymeric thickeners and a cationic photoinitiator. These coating materials are highly transparent to UV radiation used to write optical gratings in the optical fibers but still absorb sufficiently at other wavelengths to be cured effectively using UV radiation.
