Abstract
Provided is a radiation-curable, glass optical fiber coating composition which when suitably cured exhibits resistance to attack from hydrocarbon gel cable filing material. The composition contains PA1 about 10 to about 90% by weight of a first radiation-curable oligomer; PA1 from 0 to about 40% by weight of a reactive diluent; PA1 from 0 to about 40% by weight of a photoinitiator; PA1 from 0 to about 10% by weight of a pigment; and PA1 about 10 to about 90% by weight of a second radiation-curable oligomer according to the following formula: EQU R.sup.1 -L.sup.1 -C.sup.1 -L.sup.2 -R.sup.2 (1) PA1 where: PA2 R.sup.1 and R.sup.2, independently, each represent a radiation-curable functional group; PA2 L.sup.1 and L.sup.2, independently, each represent an alkyleneoxy chain having from about 2 to about 40 carbon atoms, wherein L.sup.1 and L.sup.2 are linked to C.sup.1 through an oxygen atom PA2 C.sup.1 comprises a hydrocarbon having from about 5 to about 40 carbon atoms and containing at least one cyclic group.
