UV-curable, special coding inks for optical fibers

A UV-curable, special coding ink for optical fibers consists chiefly of UV- curable prepolymers, coloring materials, and a photoinitiator. The UV-curab le prepolymers are silicone epoxy benzoic (SEBA) and alicyclic hydrocarbon epoxy acrylate(ACEA). The coloring materials are disacrylate urethane acryl ate (RUA), disperse blue urethane acrylate (BUA), acridine yellow urethane acrylate(YUA), pr their mixtures. The relationships of component-property o f UV-curable, special coding inks were studied. The typical UV-curable, spe cial coding inks were used to color the optical fibers.
