<p>The invention relates to a radiation-curable coating, ink or matrix composition comprising: (A) a polyester (meth)acrylate oligomer comprising more than about 1 mole of diacid, (B) optionally, a reactive diluent, and (C) optionally, a photoinitiator, wherein the composition when cured and aged at 85°C and 85% Relative Humidity for 10 days is hydrolytically stable to such an extent that the coating, ink or matrix maintains mechanical integrity. The invention further relates to said compositions for use as a primary coating composition, which, after cure, has a modulus of less than about 5 MPa, for use as a secondary coating or ink composition and for use as a matrix material, which, after cure, has a modulus of at least about 5 Mpa. The invention also relates to a coated and optionally inked optical fiber and to an optical fiber ribbon comprising a coating, ink, or matrix material as described above.</p> |
