Abstract:
1. A liquid resin composition for production of an optical waveguide, the liquid resin composition comprising: (A) a (meth)acrylate polymer which is a copolymer of bisphenol-A di(meth)acrylate and a diacid anhydride, in a proportion of not less than 60 wt % based on the overall weight of the resin composition; (B) at least one liquid thiol monomer selected from a group consisting of pentaerythritol tetrakis(3-mercaptopropionate), tris[(3-mercaptopropionyloxy)ethyl]isocyanurate, trimethylolpropane tris(3-mercaptopropionate) and dipentaerythritol hexakis(3-mercaptopropionate); and (C) a photopolymerization initiator, wherein the thiol monomer (B) is present in a proportion of 1 to 10 parts by weight based on 100 parts by weight of the (meth)acrylate polymer (A).
