ABSTRACT:
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.
