  • Patent number: 8735529
    Abstract: A curing catalyst (clathrate compound) for which the curing reaction is suppressed at low temperatures, allowing an improvement in the one-pot stability, but which can effectively cure a resin upon heat treatment. The clathrate compound includes at least an isophthalic acid compound represented by Formula (I), where R1 represents a C1 to C6 alkyl group, a C1 to C6 alkoxy group, a nitro group, or a hydroxyl group, and an imidazole compound represented by a Formula (II) where R2 represents a hydrogen atom, a C1 to C10 alkyl group, a phenyl group, a benzyl group, or a cyanoethyl group, and R3 to R5 each independently represents a hydrogen atom, a nitro group, or a halogen atom, or a C1 to C20 alkyl group, phenyl group, benzyl group, or C1 to C20 acyl group that may have a substituent.
