Patent ID: 8686108

Claim:
An aluminum chelate latent curing agent in which an aluminum chelating agent and an arylsilane compound or a hydrolysate thereof are held in a polymer obtained by: subjecting the aluminum chelating agent, the arylsilane compound, and a polyfunctional isocyanate compound to an emulsifying treatment, and then subjecting the polyfunctional isocyanate to interfacial polymerization in the presence of a water-soluble epoxy compound, wherein: the aluminum chelating agent does not have an alkoxy group bonded to the aluminum, and the arylsilane compound is represented by the formula (A), (Ar)mSi(OR)nâ€ƒâ€ƒ(A) where, in the formula (A), m is 2 or 3, the sum of m and n is 4, Ar represents an optionally-substituted aryl group, R represents a hydrogen atom, a methyl group, or an ethyl group, and when n is 2, the two Rs may be the same or different.
