PROBLEM TO BE SOLVED: To obtain a new imidazole compound capable of developing excellent curability and storage stability, useful as an epoxy resin curing agent by reacting an imidazoline compound with an isocyanate group-containing compound. SOLUTION: This imidazole compound is obtained by reacting an isocyanate group-containing compound (e.g. n-propyl isocyanate) with 1-(2-aminoethyl)-2- methulimidazole of formula I, for example, a compound of formula II. The epoxy resin curing agent is obtained by making the curing agent include the imidazoline compound as an active ingredient. The amount of the imidazoline compound as a curing agent added is preferably 0.002-50 pts.wt. based on 100 pts.wt. of an epoxy resin. Consequently the objective high-purity imidazole compound having a high molecular weight and a slight volatile content during curing is provided and an excellent epoxy resin curing agent can be expected.
