Abstract
A radiation-curable, optical fiber coating composition has enhanced color stabilization and is formulated from a composition containing at least one radiation-curable oligomer or monomer. A concentration of urethane and ether linkages in the radiation-curable composition is such that a cured optical fiber coating formed from said radiation-curable composition exhibits a .DELTA.E of about 40 or less after being exposed for 96 hours to 150.degree. C. and then for 144 hours to 180.degree. C. Also provided is a radiation-curable optical fiber coating composition which is substantially urethane-free.
