An aromatic amine compound capable of satisfactorily forming a cured product having exceptional alkali resistance by reaction with an epoxy compound; a curing agent for an epoxy compound, the curing agent including the aromatic amine compound; a curable composition including the curing agent for an epoxy compound; a cured product of the curable composition; a method for producing the cured product; and a method for producing the abovementioned aromatic amine compound. The aromatic amine compound has a structure such that a specific position in a central skeleton comprising a fused ring such as a fluorene ring is substituted with a side-chain group including two aromatic groups linked by a flexible bond such as an amide bond, at least one amino group is bonded to the end of the side-chain group, and the structure has no hydroxyl groups.
The reaction of 1,1,1-tris(hydroxymethyl)ethane (1a), 2-ethyl-2-(hydroxymethyl)-1, 3-propanediol (1b), pentaerythritol (1c), or 1,2, 6-hexanetriol (1e) with epichlorohydrin in the presence of potassium hydroxide in dimethyl sulfoxide gave the corresponding tri- or tetraglycidyl ethers 3a-c, e in high yields. This procedure was also applicable to the preparation of the phenolic polyglycidyl ethers.

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 R
1
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 R
2
represents a hydrogen atom, a C1 to C10 alkyl group, a phenyl group, a benzyl group, or a cyanoethyl group, and R
3
to R
5
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.
