One aspect of the present invention relates to an optical fiber coating composition including a titanate or zirconate coupling agent. The composition has, when cured, a Young's modulus of greater than about 50 MPa. Another aspect of the present invention relates to a coated optical fiber including a glass fiber; and a coating located not less than about 5 microns away from an outer surface of the glass fiber, the coating being the polymerization product of a curable composition, the curable composition including a titanate or zirconate coupling agent. The coating compositions of the present invention may be used as secondary coatings and as marking inks for optical fibers. Use of titanate or zirconate coupling agents in secondary coating compositions can provide increased wet aging properties to the cured secondary coating. Use of titanate or zirconate coupling agents in ink compositions can provide increased pigment dispersion in the ink. |
