Provided is a radiation-curable, glass optical fiber coating composition whi ch 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 % b y 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): R1 - L1 - C1 - L2 - R2, where R1 and R2, independently, each represents a radiation-curable functional group; L1 and L2, independently, each represents an alkyleneoxy chain having from about 2 to about 40 carbon atoms , wherein L1 and L2 are linked to C1 through an oxygen atom; C1 comprises a hydrocarbon having from about 5 to about 40 carbon atom s and containing at least one cyclic group.
