Abstract: The invention provides a coating composition having: (A) 30-80 % by weight of a urethane oligomer having three types of moieties, a polyether and/or polyolefin backbone, an aromatic group having one or more alkyl substituents, and reactive termini, the three types of moieties being connected via urethane and/or urea linkages, the aromatic group being connected to a urethane and/or urea linkage via the one or more alkyl substituents; (B) 15-65 % by weight of one or more reactive diluents, each diluent being terminated with at least one end group capable of reacting with the reactive terminus of (A); optionally (C) 0-10 % by weight of at least one photoinitiator; optionally (D) 0-5 % by weight antioxidant; and optionally (E) 0-30 % by weight adhesion promotor. The invention also relates to a coating composition in which the urethane oligomer (A) has the general formula (1): R3-¢L-R2-NH-CO-O-R1!y, wherein: R1 is a reactive terminus, R2 is an aromatic group having one or more alkyl substituents, wherein the urethane (O-CO-N-) group and L are attached to the one or more alkyl substituents, R3 is an oligomer based on a polyether or polyolefin or a mixture thereof, L is a urethane and/or urea linkage, and Y is 2 or greater. The invention further provides coatings made by curing the coating compositions.

Abstract: The invention relates to a radiation-curable resin coating composition having extended shelf life and being adapted for use in forming a radiation-cured coating on an optical glass fiber for signal transmission, which when suitably cured provides reliable and consistent resistance to delamination from the optical glass fiber, said uncured coating composition comprising: a radiationcurable oligomer or monomer, and a coupling agent containing at least one functionally-effective group capable of binding to glass and which is susceptible to hydrolysis under normal shelf storage conditions for said coating composition; said coating composition having a controlled stoichiometric water content less than the stoichiometric amount of said functional groups present in said coupling agent.
