Abstract: Radiation-curable compositions, and methods of making the same, for providing a wide variety of substrates with a durable, colored coating or colorant are disclosed. The color is at least in part provided by chromophore molecules that are covalently bonded to other components within the radiation-curable composition. A telecommunication element having a durable color identifying polymeric coating thereon is also disclosed. The telecommunication element comprises an elongated communication transmission medium, such as an optical fiber or an optical fiber ribbon, and a radiation-cured polymeric coating having an identifying color applied on at least a portion of the transmission medium.

Abstract: A radiation-curable coating composition containing an oligomeric system containing (a) individual oligomers that each contain an oligomeric backbone having chemically tethered thereto one or more radiation-curable components and (b) individual oligomers that each contain an oligomeric backbone having chemically tethered thereto one or more formulation components of a radiation-curable coating composition, wherein each individual oligomer of the group of individual oligomers (a) may be the same as or different from each individual oligomer of the group of individual oligomers (b), and each formulation component is a photoinitiator group, an adhesion promoter group, or a fullerene.
