  • Radiation curable colored coating composition
    Patent number: 6797740
    Abstract: The invention relates to a radiation curable colored coating composition for coloring a coated optical fiber wherein the coating, when disposed and cured to surround an optical fiber coated with an internal coating, and when said colored fiber is coated with a matrix material and assembled into an optical fiber ribbon, said colored coating has a degree of adhesion to the internal coating which is higher than the degree of adhesion to the matrix material and said optical fiber assembled into said optical fiber ribbon shows, upon aging for at least two weeks in water at 60° C., an increase in the attenuation of the transmitted signal at 1550 nm of less than 0.05 db/km with respect to the attenuation of the assembled optical fiber measured before aging. The invention also relates to said colored coating composition when used in an optical fiber ribbon.
    Type: Grant
