An ultraviolet curing coating composition includes unsaturated carboxylic acid and salts thereof, a compound containing a carbonyl group, a thickener, a photoinitiator, and deionized water. The added value of a fiber attenuation coefficient of the composition is less than 0.02 dB/km. A coating internally cross-linked in a network shape is formed on the surface of an optical fiber by interaction between active groups, and the coating has a faster water absorption rate and better water blocking effect and is not easy to water loss. Under the optimal mixing of raw materials, the water absorption rate of the coating composition is maintained at 3 to 15 times and further can be controlled at 3 to 10 times, so that a water-soluble tensile coating coated on the optical fiber will not excessively squeeze the optical fiber after absorbing water to cause the attenuation of the optical fiber over the standard.
