Abstract: Disclosed herein are non-aqueous, radiation curable inkjet inks exhibiting stability at high shear rate (good rheological stability), stability at high temperatures, and/or stability in inkjet print heads, especially impulse inkjet print heads. The inks have a wide process window at a variety of print speeds using an impulse inkjet print head.

Abstract: The present invention provides a radiation curable coating composition for forming a polymeric coating on a glass optical fiber, the composition comprising a mixture of: a base radiation curable liquid composition capable of forming a polymeric coating; at least one adhesion promoter selected from the group consisting of bis-silyl amines, diacrylated silane tertiary amine, acetoxy functional silanes, trifunctional isocyanurates and mixtures thereof, and 0 to about 10 percent by weight of one or more photoinitiators. The present invention also includes a coated optical fiber, a method for making an optical fiber and compositions containing adhesion promoters that do not undergo free radical reaction with base radiation curable pre-polymer of the composition.
