がある。The imidazole compound represented by the general formula (I) has an effect of accelerating the curing of the resin composition of the present invention, and can be used alone or in combination with another imidazole compound. Other imidazole compounds used in combination include 2-methylimidazole,
-Ethyl-4-methylimidazole, 2-phenylimidazole, 1,2-dimethylimidazole, 1-benzyl-2-methylimidazole, 2-undecylimidazole and the like. The imidazole compound represented by the general formula (I) is used in an amount of 0.005 to 10 parts by weight based on 100 parts by weight of the component (A). If the amount of the imidazole compound is less than 0.005 parts by weight, the added effect is not sufficiently exhibited, and if it exceeds 10 parts by weight, the effect is not changed. The total amount of the imidazole compound is preferably in the range of 1 to 10 parts by weight based on 100 parts by weight of the bisphenol F epoxy resin. If the total amount of the imidazole compound is too small, the curability tends to be poor. If the amount exceeds 10 parts by weight, the curing does not change, but the pot life at room temperature tends to be significantly shortened.
