<p>A special epoxy resin material has been found to give a cured product having excellent ultraviolet-ray transmission. The cured product also has excellent heat resistance and moisture resistance and also high mechanical strength. This epoxy resin material therefore is very useful as a protection or support material for an ultraviolet-ray sensitive element such as EPROM., CCD, TFT, laser disk, etc. and also as an ultraviolet-ray transmissive ink, optical material or adhesive. The special epoxy resin material is featured by its chemical construction that it has a glycidyl group or glycidyl groups coupled to a nitrogen atom or nitrogen atoms of a triazine ring of an isocyanuric acid.</p> |
