    • A latent epoxy resin curing agent is provided which can be manufactured without using an amphiphilic polymer compound requiring a painful trial and error selection process, exhibits excellent solvent resistance and low-temperature fast-curing ability, and contains an imidazole-based compound as a main component. In the latent epoxy resin curing agent containing the imidazole-based compound as a main component, the adduct particles of the epoxy-based compound and the imidazole-based compound are coated with an ethyl cellulose film, and the surface thereof is crosslinked with a polyfunctional isocyanate compound. The epoxy-based compound, the imidazole-based compound, and ethyl cellulose are dissolved in a predetermined saturated hydrocarbon-based solvent under stirring and heating. Then, the epoxy-based compound and the imidazole-based compound are subjected to adduct reaction to obtain a slurry of the adduct. After the slurry was cooled, the polyfunctional isocyanate compound is added thereto to crosslink the ethyl cellulose film.

    • An aluminum chelate-based latent curing agent capable of curing a thermosetting epoxy resin under the condition of relatively low temperature in a short period of time is provided. Furthermore, a method for manufacturing the latent curing agent is provided, in which the curing conditions of the aluminum chelate-based latent curing agent can be controlled relatively easily.The aluminum chelate-based latent curing agent is prepared by reacting an aluminum chelate agent with a silsesquioxane type oxetane derivative in the presence of a water insoluble or poorly water-soluble cellulose ether, whereby latency properties are imparted thereto. This latent curing agent contains a coating layer composed of the water insoluble or poorly water-soluble cellulose ether. Preferably, the surface is treated with an isocyanate compound.

    • A latent epoxy resin curing agent is provided which exhibits excellent solvent resistance and low-temperature fast-curing ability, and contains an imidazole-based compound as a main component. In the latent epoxy resin curing agent containing the imidazole-based compound as a main component, adduct particles formed through adduct reaction of an epoxy-based compound with the particulate imidazole-based compound are coated with an ethyl cellulose film. Furthermore, the surfaces of the adduct particles may be crosslinked with a polyfunctional isocyanate compound. A mixture of the epoxy-based compound, the particulate imidazole-based compound, and ethyl cellulose in a predetermined saturated hydrocarbon-based solvent is heated under stirring. Then, the epoxy-based compound and the particulate imidazole-based compound are subjected to adduct reaction to give a slurry of the adduct. After the slurry is cooled, the latent epoxy resin curing agent is filtrated.
