Zusammenfassung:	PURPOSE:The titled composition excellent in both curability and storage stability, comprising an epoxy resin base composition containing an epoxy resin and a polycarboxylic acid anhydride, an alkali (alkaline earth) metal and a hydroxyl group-containing compound. CONSTITUTION:An epoxy resin base composition (A) containing an epoxy resin (e.g., bisphenol A diglycidyl ether) and a polycarboxylic acid anhydride (e.g., methylcyclopentadiene/maleic anhydride adduct is mixed with 0.5X10-10X 10wt%, based on component A, alkali (alkaline earth) metal (e.g., sodium methylate), 0.05-0.5wt%, based on component A, hydroxyl group-containing compound (e.g., organic monocarboxylic acid/epoxy resin adduct) and, optionally, well-known additives, fillers, pigments, sealants, etc.
