Abstract
The present disclosure provides an optical waveguide formation photosensitive epoxy resin composition which contains an epoxy resin and a photo-cationic polymerization initiator, wherein the epoxy resin includes a solid epoxy resin component alone. Thus, a core layer forming material can be provided, which has higher R-to-R (roll-to-roll) adaptability and higher transparency at a wavelength of 850 nm. Therefore, a core layer for an optical waveguide can be formed as having excellent R-to-R adaptability, higher transparency and a lower loss by using the optical waveguide formation photosensitive epoxy resin composition without changing the conventional production process.
