Abstract (en)

[origin: WO9321248A1] A liquid curable resin composition comprising a urethane (meth)acrylate obtained by the reaction of: (A) a polyether polyol compound containing, as structural units, groups represented by the following formulas: (1) -CH2CH2O-, (2) -CH2CH(R)O-, and (3) one or more groups selected from groups (a) -CH2CH2CH2CH2O-, (b), and (c) as shown above, wherein R represents an alkyl group containing two or more carbon atoms, and R<1> and R<2> are independently selected from a hydrogen atom or a methyl group; (B) a polyisocyanate compound; and (C) a (meth)acrylate compound having a hydroxy group. The composition exhibits a high curing rate, its cured material has a low Young's modulus and a high gel ratio, provides superior heat resistance and light resistance, and generates only a small amount of hydrogen gas. It is thus particularly suitable as a material for optical fiber coating.
