Optical waveguide and dry film for optical waveguide production |
摘要 |
The present invention provides an optical waveguide excellent in all of transparency, a bending property and heat resistance and a dry film for manufacturing an optical waveguide. A clad layer of the optical waveguide according to the present invention is formed by using a dry film containing a polymer comprising at least a (meth)acrylate monomer with an epoxy group and a (meth)acrylate monomer without an epoxy group; and cationic or anionic curing initiator. |

1. An optical waveguide comprising a core and a clad enveloping the core, wherein at least the clad is a cured product by epoxy crosslinking a polymer comprising a (meth)acrylate monomer with an epoxy group (A) which is epoxycyclohexylmethyl (meth)acrylate represented by the general formula (2): wherein R denotes hydrogen or a methyl group; glycidyl (meth)acrylate represented by the general formula (3): wherein R denotes hydrogen or a methyl group; or a mixture thereof, and a (meth)acrylate monomer without an epoxy group (B) represented by the general formula (1): wherein R denotes hydrogen or a methyl group. |
