Production manner of the Acid anhydride epoxy resin curing agent, the Acid anhydride epoxy resin curing agent, the epoxy resin constituent, the hardened material and the optical

摘要

This invention, production method of the acid anhydride epoxy resin cement, the acid anhydride epoxy resin cement, the epoxy resin composition, regards the hardening ones and the photosemiconductor device. Production method of the acid anhydride epoxy resin cement of this invention the blend which includes the polyvalent carboxylic acid anhydride and the polyester resin, features that the gaseous hydrogen and the process which is heated under existing of the hydrogenation catalyst are included.
