Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the storage stability of a mixture of an acid anhydride-based curing agent, and a tertiary amine-based curing accelerator for an epoxy resin. SOLUTION: One or more kinds of hydroxybenzoic acid esters (C) represented by general formula (1) [wherein, R1O is a 2-3C oxyalkylene group; R2is a 1-12C linear or branched alkyl group or a 5-12C cycloalkyl group; and n is an integer of 0-10] of 0.1-5 pts. wt. based on the acid anhydride-based curing agent (A) for the epoxy resin of 100 pts. wt. is compounded with a mixture of the component (A) and the tertiary amine-based curing accelerator (B).
