<p>Provided is a radiation-curable, glass optical fiber coating composition which when suitably cured exhibits resistance to attack from hydrocarbon gel cable filling material. The composition contains about 10 to about 90 % by weight of a first radiation-curable oligomer; from 0 to about 40 % by weight of a reactive diluent; from 0 to about 40 % by weight of a photoinitiator; from 0 to about 10 % by weight of a pigment; and about 10 to about 90 % by weight of a second radiation-curable oligomer according to the following formula (1): R?1 - L1 - C1 - L2 - R2¿, where R?1 and R2¿, independently, each represents a radiation-curable functional group; L?1 and L2¿, independently, each represents an alkyleneoxy chain having from about 2 to about 40 carbon atoms, wherein L?1 and L2¿ are linked to C1 through an oxygen atom; C1 comprises a hydrocarbon having from about 5 to about 40 carbon atoms and containing at least one cyclic group.</p> |
