POLYMER OPTICAL WAVEGUIDE AND PROCESS FOR PRODUCTION THEREOF

Document Type and Number:

WIPO Patent Application WO/2006/009173

Kind Code:

A1

Abstract:

A clad layer and a core layer are obtained by a stamper method through UV curing by using a clad material consisting of a UV-curable composition (I) which comprises a fluorinated acrylic copolymer (A) obtained by copolymerizing a fluorine-containing (meth)acrylate (a1) with a nonfluorinated mono(meth)acrylate (a2), a fluorine-containing (meth)acrylate (B), a nonfluorinated mono(meth)acrylate (C), and a poly- functional (meth)acrylate (D) and which gives a product of curing having a glass transition temperature of 60 to 150&ring C and a core material consisting of a UV-curable composition (II) which comprises the above components (A) to (D) and which gives a product of curing having a glass transition temperature of 60 to 150&ring C and a refractive index higher than that of the product of curing of the clad material.
