  • Ribbon assemblies and ink coating compositions for use in forming the ribbon assemblies
    Patent number: 6130980
    Abstract: Provided is a ribbon assembly having the functional capability of providing break-out of ink coated optical glass fibers from said ribbon assembly. The monomers, oligomers and photoinitiator for forming an ink coating on the optical glass fibers contained in the ribbon assembly have been selected to provide an average percentage of reacted acrylate unsaturation which provides a level of adhesion between a matrix material and an ink coating that is less than a level of adhesion between the ink coating and the coated optical glass fiber to provide break-out of the ink coated optical glass fiber from said ribbon assembly. Also provided are ink coating compositions adapted to form ink coatings suitable for use on optical glass fibers contained in the ribbon assembly.
