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.

[ What is claimed is:] [1.] A ribbon assembly having the functional capability of providing break-out of ink coated optical glass fibers from said ribbon assembly, said ribbon assembly comprising:a plurality of coated optical glass fibers;an ink coating on at least one of said coated optical glass fibers; anda matrix material directly bound to said ink coating and binding said plurality of coated optical fibers together, wherein said ink coating being formed from a radiation curable ink coating composition comprising:a radiation-curable carrier system containing a radiation-curable oligomer, a radiation curable monomer, and at least one photoinitiator; anda pigment dispersed in said radiation-curable carrier system, wherein said monomers, oligomers and photoinitiator are selected to provide an average percentage of reacted acrylate unsaturation which provides a level of adhesion between said matrix material and said ink coating that is less than a level of adhesion between said ink coating and said coated optical glass fiber to provide breakout of said ink coated optical glass fiber from said ribbon assembly when said ink coating composition is cured by exposure to an ultraviolet radiation dose of about 0.125 joules per square centimeter.
