PROBLEM TO BE SOLVED: To provide an aluminum chelate-based latent curing agent capable of curing a thermosetting epoxy resin at a comparatively low temperature in a short time, and to provide a method for producing the aluminum chelate-based latent curing agent, by which method curing conditions of the aluminum chilate-based latent curing agent can be controlled comparatively easily. SOLUTION: The aluminum chelate-based latent curing agent is obtained by reacting an aluminum chelating agent with a silsesquioxane-type oxethane derivative in the presence of a water-insoluble or poorly water-soluble cellulose ether. The latent curing agent has a coating layer composed of the water-insoluble or poorly water-soluble cellulose ether. The surface of the latent curing agent is preferably treated with an isocyanate compound. COPYRIGHT: (C)2007,JPO&INPIT
