RESIN COMPOSITION FOR OPTICAL WAVEGUIDE, DRY FILM, OPTICAL WAVEGUIDE, AND PHOTOELECTRIC COMPOSITE WIRING BOARD USING SAME |
摘要 |
Provided are a resin composition which offers both high transparency and a low linear expansion coefficient and can be used as a material for a dry film, and also a dry film obtained from this composition, an optical waveguide, and a photoelectric composite wiring board. The resin composition for an optical waveguide includes: (A) an epoxy resin constituted by a solid epoxy resin with one or less hydroxyl group in a molecule, and a liquid epoxy resin with one or less hydroxyl group in a molecule; (B) a curing agent with one or less hydroxyl group in a molecule; and (C) a nanosize silica sol, and contains no compound including two or more hydroxyl groups in a molecule as a resin component. |
