ADHESIVE COMPOSITION FOR OPTICAL WAVEGUIDE, ADHESIVE FILM FOR OPTICAL WAVEGUIDE AND ADHESIVE SHEET FOR OPTICAL WAVEGUIDE EACH USING THE SAME, AND OPTICAL DEVICE USING ANY OF THEM

摘要

The present invention provides an adhesive composition for an optical waveguide which comprises (a) an epoxy resin, (b) a curing agent and (c) a high molecular compound, in which a total light transmittance and a light transmittance in a wavelength of 700 to 1600 nm in a cured matter of the adhesive composition are 80 % or more and in which a transparency is consistent with a heat resistance, an adhesive film for an optical waveguide prepared by forming the above adhesive composition into a film form, an adhesive sheet for an optical waveguide comprising the above adhesive composition and a supporting base material and an optical device produced by using them.
