Claim 2
Dependent Claim
49 words
An optical fiber comprising an optical fiber substrate selected from the group consisting of silica, glass and quartz, and a coating composition bonded to said fiber substrate, said composition comprising the cured reaction product of at least one ethylenically unsaturated monoene, an ethylenically unsaturated polyene, and a curing initiator.
Claim 3
