| titleOfInvention | Process for producing optical waveguide |
| abstract | The present invention relates to a process for producing an optical waveguide, which comprises forming an undercladding layer on a surface of a substrate; forming a photosensitive resin composition layer on the undercladding layer; irradiating a surface of the photosensitive resin composition layer with ultraviolet through a photomask having a given pattern to conduct an exposure; removing an unexposed area of the photosensitive resin composition layer after the exposure by dissolving the unexposed area with a developing liquid to thereby form a core layer; and forming an overcladding layer on the core layer, in which the developing liquid is an aqueous γ-butyrolactone solution having a concentration of from 10 to 99% by weight. According to the process, it is possible to obtain an optical waveguide in which neither the core layer itself nor the interface between the core layer and the undercladding layer cracks and which has a small light loss. |
