Ribbon assemblies and radiation-curable ink compositions for use in forming the ribbon assemblies

摘要

Provided is a ribbon assembly having the functional capability of providing break-out of ink coated or colored outer primary coated optical glass fibers from the ribbon assembly. The ink coating or colored outer primary coating is formulated from a benzophenone compound and at least about 1 wt. % of a homolytic photoinitiator to provide a level of adhesion between the ink coating or colored outer primary coating and matrix material which is less than the level of adhesion between the ink coating or colored outer primary coating and an adjacent underlying coating. Also provided are ink coating and colored outer primary coating compositions adapted to form ink coatings and colored outer primary coatings suitable for use on optical glass fibers contained in a ribbon assembly.
