    摘要： An optical waveguide and a production method thereof that can provide increased production efficiency, improved workability, and/or production stability. According to non-limiting example embodiments a photopolymerizable resin composition comprising a fluorene derivative and a photoacid generator is coated over an under clad layer and then is dried, to form a resin layer having substantially no surface tack. The resin layer is exposed to light in the state of being contacted with a photo mask by a contact exposure method and then is developed, to form the resin layer into a pattern. Thereafter, the resin layer is cured to form a core layer and then an over clad layer is formed on the under clad layer in such a manner as to cover the core layer, to thereby produce an optical waveguide.

    摘要： A production method of an optical waveguide that can provide increased production efficiency and can also provide improved workability and production stability and provide an optical waveguide produced by the production method of the optical waveguide. A varnish comprising photopolymerizable resion composition comprising a fluorene derivative and a photoacid generator is coated over an under clad layer 2 and then is dried, to form a resin layer 4 having substantial no surface tack. Sequentially, the resin layer 4 is exposed to light in the state of being contacted with a photo mask 5 by a contact exposure method and then is developed, to form the resin layer 4 into a pattern. Thereafter, the resin layer 4 is cured to form a core layer 3 and then an over clad layer 6 is formed on the under clad layer 2 in such a manner as to cover the core layer 3, to thereby produce an optical waveguide. This method can allow the forming of the resin layer 4 having no surface tack, and as such can allow the use of the contact exposure to expose the resin layer to light. Hence, the number of processes and time-consuming and complicated works involved in the interposition of the spacer can be reduced, thus providing increased production efficiency.
