A curing catalyst (clathrate compound) which is inhibited from catalyzing a curing reaction at low temperatures, is effective in improving one-pack stability, and can effectively cure a resin upon heating. The clathrate compound is characterized by comprising an isophthalic acid compound represented by the formula (I): (I) [wherein R1 represents C1-6 alkyl, etc.] and an imidazole compound represented by the formula (II): (II) [wherein R2 represents hydrogen, C1-10 alkyl, etc.; and R3 to R5 each independently represents hydrogen, nitro, etc.]. |
