ABSTRACT:
The separable optical fiber ribbon in accordance with the present invention is an optical fiber ribbon in which a plurality of colored optical fibers arranged in parallel are coated with a collective coating resin so as to be integrated into an optical fiber ribbon, and a plurality of such optical fiber ribbons are arranged in parallel and coated with a binding resin; wherein the binding resin is obtained by curing a UV-curable resin composition satisfying the condition represented by the following expression (1):in-line-formulae description="In-line Formulae" end="lead"?1.0×10−4≦(W·N/100MW)≦4.0×10−4  (1)in-line-formulae description="In-line Formulae" end="tail"?where W is the compounding ratio [wt %] of a urethane acrylate compound contained in the resin composition, N is the number of urethane groups in one molecule of the urethane acrylate compound, and MWis the average molecular weight of the urethane acrylate compound.
