ABSTRACT:
Optical fibers are coated with a radiation-curable liquid, polyethylenically unsaturated coating composition consisting essentially of an organic polysiloxane having from 2 to 6 reactive side chains each of which carry a functional group providing one reactive site which has been reached to provide a single radiation-curable monoethylenically unsaturated side chain. There are about one such side chain for every 500 to 5,000 units of molecular weight. This provides a prime coating which has a modulus of elasticity at room temperature and at -60.degree. C. below 3000.
