Provided is ribbon assembly having the functional capability of providing break-out of color coded coated glass fibers from said ribbon assembly. The monomers, oligomers and photoinitiator for forming the color 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 a colored coating that is less than a level of adhesion between the colored coating and the coated optical glass fiber to provide break-out of the color coded optical glass fiber from said ribbon assembly. Also provided are colored coating compositions adapted to form colored coatings suitable for use on optical glass fibers containing in the ribbon assembly.
