ABSTRACT:
An ultraviolet-curing resin composition comprising an acrylic oligomer, tris(2-hydroxyethyl)isocyanurate triacrylate, a reactive diluent and a photopolymerization initiator, wherein the acrylic oligomer is a urethane obtained from diphenylmethane diisocyanate, a polytetramethylene glycol having a molecular weight of 650 to 1,300 and a monoacrylate having a hydroxy group, the amount of tris(2-hydroxyethyl)isocyanurate triacrylate is 1 to 100 parts by weight for 100 parts by weight of the urethane acrylate, and the reactive diluent is an acrylic monomer. A mixture of tris(2-hydroxyethyl)isocyanurate triacrylate and a terminal diacrylate having a cycloacetal group may be used in place of tris(2-hydroxyethyl)isocyanurate triacrylate. The compositions are useful as secondary cladding materials and buffer materials in optical fiber units.
